                                OpenVMS VAX Version 5.5-2H4 Release Notes


              This chapter contains general OpenVMS VAX Version 5.5-
              2H4 release notes plus specific release notes about the
              StorageWorks RAID Array 110 Subsystem with SCSI-2 tagged
              command queuing (TCQ) and DEC LAN device driver support.

        1.1 General Release Notes

              This section provides guidelines for installing and
              updating your system, correcting problems, modifying system
              parameters, and using the DUP Driver Utility on VAX 4000
              series systems.

        1.1.1 Guidelines for Installing and Updating

              The following sections provide information about the
              distribution media and guidelines for updating to or
              installing the OpenVMS VAX Version 5.5-2H4 operating

    OpenVMS VAX Version 5.5-2H4 Release Notes
    1.1 General Release Notes


    1.1.1.2 When to Update

          You can update directly to Version 5.5-2H4 of the OpenVMS
          VAX operating system only if your VAX computer is running
          Version V5.5-2 of the OpenVMS VAX operating system. (You
          cannot update from any other version of the operating
          system, including Version A5.5-2.)

          If you are adding a new VAX computer (including VAX 4000
          Model 100A, 500A, 600A, 700A, and MicroVAX 3100 Model 90
          systems) to an existing cluster, you can update directly to
          Version 5.5-2H4 of the OpenVMS VAX operating system if you
          perform the update on the Version V5.5-2 boot node in the
          cluster.

                                                1.1 General Release Notes


                ________________________ Note ________________________

                When deciding whether to update your system, note the
                following:

                o  The update procedure does not initialize the system
                   disk; that is, it leaves layered products and user
                   files intact.

                o  You can apply the update on a system running only
                   OpenVMS VAX Version V5.5-2.

                   If your system is running any version of OpenVMS
                   VAX (including Version A5.5-2) prior to Version
                   V5.5-2, you must upgrade to Version V5.5-2 before
                   applying this update. (See the VMS Version 5.5
                   Upgrade and Installation Manual for a description
                   of the upgrade procedure.)

                o  You cannot upgrade to Version 5.5-2H4 of the
                   OpenVMS VAX operating system. You must update your
                   system or perform a full installation.

                ______________________________________________________

        1.1.1.3 How to Update

              To update your system to Version 5.5-2H4 of the OpenVMS
              VAX operating system, follow the procedures described in
              Chapter 2.

        1.1.1.4 When to Install

              You must perform a complete installation (rather than
              an update) if your system meets one of the following
              conditions:

              o  Your VAX computer is new, including VAX 4000 Model 100A,
                 500A, 600A, 700A, and MicroVAX 3100 Model 90 systems.
                 (However, if you are adding one of these new systems
                 to an existing cluster, you do not need to perform an
                 installation if you update the Version V5.5-2 boot node
                 in that cluster.)

              o  Your VAX computer has never had any version of the
                 OpenVMS VAX operating system running on it.

              o  Your VAX computer is running the OpenVMS VAX operating
                 system and you want to destroy the contents of the
                 system disk (both VMS and user files).

    1.1 General Release Notes


    1.1.1.5 How to Install

          To install the OpenVMS VAX Version 5.5-2H4 operating
          system, do the following:

          1. Review the the release notes in this chapter.

          2. Review the VMS Version 5.5 Release Notes and the VMS
             Version 5.5-2 Release Notes for information relevant to
             your specific computer and to installation procedures in
             general.

          3. Begin the installation with the VMS Version 5.5 Upgrade
             and Installation Manual and then refer (when instructed
             to do so) to the VMS upgrade and installation supplement
             for your VAX computer to perform specific operations.

             ________________________ Note ________________________

             As you use the VMS Version 5.5 Upgrade and
             Installation Manual to perform the installation, note
             the following supplemental information:

             o  When you boot from the InfoServer, enter ISL_SVAX_
                U2H4055 when the installation procedure prompts you
                for the file name that contains the initial system
                load (ISL) boot program.

             o  When you create the new system disk, specify
                VMS2H4055.B as the save-set name when you enter
                the backup command that transfers the save set from
                your source drive to your target drive.

             ______________________________________________________

    1.1.2 Nonmatching File Identifiers

          During the update procedure (step 9 in Section 2.3), the
          procedure checks the file identifiers of the files being
          replaced by the installation of the OpenVMS VAX Version
          5.5-2H4 operating system.

          The procedure assumes that the update is being installed
          on an OpenVMS VAX Version V5.5-2 system. However, if
          your Digital Customer Support Center supplied you with
          a remedial kit after the release of the OpenVMS VAX
          Version V5.5-2 operating system, that remedial kit might
          have updated one of the files that will be replaced by
          the OpenVMS VAX Version 5.5-2H4 update. In such a case,

                                                1.1 General Release Notes


              the file supplied by the remedial kit might have a file
              identifier that is different from the file supplied by the
              OpenVMS VAX Version V5.5-2 release.

              If the Version 5.5-2H4 update procedure encounters a file
              that has an identifier that does not match and you choose
              to continue with the update, the procedure will replace
              the file, possibly overwriting the function supplied by
              the remedial kit. Therefore, if you are not sure whether
              you should replace the identified file, answer NO when the
              update procedure prompts you to continue the update. Then
              contact your local Digital Representative about the file in
              question. (No changes to the system disk will occur if you
              exit from the update in this manner.)

        1.1.3 INVEXCPTN SYSGEN Crash Following SCSI Bus Reset

              It is possible for a SCSI bus reset to create a condition
              that will cause the system to crash with an INVEXCPTN when
              you execute the SYSGEN command AUTOCONFIGURE ALL or run
              SYS$UPDATE:AUTOGEN.COM. This condition affects VAXstation
              4000 series systems equipped with the PMAZ adapter, which
              supports the TURBOchannel to SCSI option (PKB, PKC, and PKR
              port drivers). The condition might also occur on systems
              that do not have a PMAZ adapter. (See Table 1-1.)

              Before you execute the SYSGEN command AUTOCONFIGURE ALL or
              run SYS$UPDATE:AUTOGEN.COM, Digital recommends that you do
              the following:

              1. Check for SCSI port device errors by entering the
                 following command:

                 $ SHOW DEVICE PK

              2. If the display lists errors for either the PKA0 or PKB0
                 port devices, create an error log file containing errors
                 that occurred since you last booted the system, by doing
                 the following:

                 a. Enter the SHOW SYSTEM command and note the value in
                    the Uptime field. For example:

    OpenVMS VAX Version 5.5-2H4 Release Notes
    1.1 General Release Notes


    $ SHOW SYSTEM

  .
  .
  .

             b. Enter the following command (including the value of
                the Uptime field with the /SINCE qualifier) to create
                an error log file named ERRORS.TMP:

              $ ANALYZE/ERROR_LOG/INCLUDE=PK/SINCE="-3-05:03:09"/OUT=ERRORS.TMP

          3. If the error log file logs a SCSI bus reset (indicated
             by the string "BUS RESET INITIATED" or "BUS RESET
             DETECTED"), do not execute the SYSGEN AUTOCONFIGURE
             ALL command or run SYS$UPDATE:AUTOGEN.COM. Instead, do
             the following:

             a. Shut down the system.

             b. Reboot.

             c. Allow the system to run for 24 hours to obtain new
                feedback information.

             d. Contact your Digital Representative.

    1.1.4 Possible INCONSTATE Crash Due to Insufficient LRPCOUNT

          If a system has been configured with no feedback
          information, the value of the system parameter LRPCOUNT
          (the number of preallocated large request packets) might
          be set too low. This low setting could cause the system to
          crash with an INCONSTATE error when you execute the SYSGEN
          command AUTOCONFIGURE ALL or run the SYS$UPDATE:AUTOGEN.COM
          procedure.

          Digital recommends, therefore, that after you install a new
          software product or add a new device, you run the system
          under a normal load for at least 24 hours before running
          SYS$UPDATE:AUTOGEN.COM. This will allow the system to build
          up enough feedback information for the operating system to
          accurately determine new values for all system parameters,
          including LRPCOUNT.

                                OpenVMS VAX Version 5.5-2H4 Release Notes
                                                1.1 General Release Notes


              If you cannot run the system for 24 hours before running
              SYS$UPDATE:AUTOGEN.COM, or if you must execute the SYSGEN
              command AUTOCONFIGURE ALL, Digital recommends that you
              enter the DCL command SHOW MEMORY before performing either
              operation. If there are at least 5 LRPs available, you
              can then run SYS$UPDATE:AUTOGEN.COM or execute the SYSGEN
              command AUTOCONFIGURE ALL. If there are less than 5 LRPs
              available, reboot the system using a larger value for the
              system parameter, LRPCOUNT.

              You can avoid this situation by making sure the system is
              configured with more LRPs than would otherwise be necessary
              if based solely on the system's hardware configuration.
              You can accomplish this by increasing the value of the
              LRPCOUNT parameter by 5 in the SYS$SYSTEM:MODPARAMS.DAT
              file. The following example shows how to add this parameter
              to SYS$SYSTEM:MODPARAMS.DAT:

              .
              .
              .
              VAXCLUSTER=0
              SCSNODE=""
              WINDOW_SYSTEM=1
              WSMAX=18000
              SPTREQ=10000
              VIRTUALPAGECNT=50000
              PROCSECTCNT=48
              ADD_LRPCOUNT=5

        1.1.5 Incorrect Image Backups from an RF73 Disk

              When performing an image backup from an RF73 disk (or a
              disk with a cluster size of 4 blocks ) to an RF74 disk
              (or a disk with a cluster size of 7 blocks ), the Backup
              utility does not check the file size when it is allocating
              space for the file being copied. As such, if the file has
              an allocation greater than the value of the CLUSTER_SIZE
              attribute established during initialization, the Backup
              utility will allocate one more cluster size number of
              blocks to the allocation size even though the actual file
              size is less than the cluster size. For example, during an
              image backup, a file that uses 6 blocks and is allocated
              8 blocks (which displays as 6/8 on the screen if you enter
              a DIRECTORY/SIZE=ALL command) shows an increase in its

                            OpenVMS VAX Version 5.5-2H4 Release Notes 1-7




























































    OpenVMS VAX Version 5.5-2H4 Release Notes
    1.1 General Release Notes


          allocation size to 14, instead of 7, after it is copied to
          the target disk.

          As a result of this problem, the following files are copied
          to the image system disk with a blocks used/allocation size
          of 6/14 blocks:

             SYS$COMMON:[SYS$LDR]LIDRIVER.EXE
             SYS$COMMON:[SYS$LDR]LPDRIVER.EXE

          This incorrect allocation size causes standalone BACKUP to
          fail on the booted image system disk.

          To correct this problem, recopy the two previously listed
          files to the same directory after the image backup, by
          using the following command (which also specifies the
          correct allocation size):

      $ COPY/ALLOCATION=7 SYS$COMMON:[SYS$LDR]LIDRIVER.EXE SYS$COMMON:[SYS$LDR]
      $ COPY/ALLOCATION=7 SYS$COMMON:[SYS$LDR]LPDRIVER.EXE SYS$COMMON:[SYS$LDR]

    1.1.6 Using the DUP Driver Utility

          The following notes supplement the information contained in
          your VAX installation supplement:

          o  For certain VAX 4000 series systems with embedded DSSI
             buses, you can specify a DSSI bus number from 0 to 3
             (rather than only 0 or 1).

          o  After you start the DUP Driver Utility, you can change
             the DSSI node name by entering the following command
             at the PARAMS> prompt (instead of SET NODE NAME). For
             example:

             PARAMS> SET NODE <BARNEY>

    1.2 StorageWorks RAID Array 110 Subsystem and TCQ Release Notes

          This section includes release information for the
          StorageWorks RAID Array 110 Subsystem and tagged command
          queuing (TCQ).

          The StorageWorks RAID Array 110 Subsystem is an
          implementation of RAID (Redundant Array of Independent
          Disks) that can be configured with no single point of
          failure. Tagged command queuing (TCQ) allows multiple IO's
          to be outstanding to a given device. (For more information

              about tagged command queuing, refer to the ANSI SCSI-2
              X3T9.2 specification.)

              Support for TCQ is available in the DK driver plus the
              port drivers listed in Table 1-1 (which lists queuing
              support that is available for specific VAX systems and
              port drivers).

    _________________________________________________________________

             ________________________ Notes ________________________

             Note the following about TCQ support and specific VAX
             computers:

             o  VAXstation 3100 series computers (Models 10,
                20, 30, 40, 38, 48, and 76) do not support TCQ.
                However, if the TCQ kit is installed on one
                of these systems, existing SCSI devices will
                still work on the PKN port driver (with a native
                adapter).

             o  VAXstation 3520 and VAXstation 3540 computers
                do not support TCQ. However, if the TCQ kit is
                installed on one of these systems, existing SCSI
                devices will still work on the PKS port driver
                (with a native adapter).

             o  VAX 4000 series computers other than the VAX 4000
                Model 100, do not support TCQ. However, if the TCQ
                kit is installed on one of these systems, existing
                SCSI devices will still work on the PKI port driver
                (with a KZQSA adapter).

             ______________________________________________________

          The following sections contain additional release
          information about the StorageWorks RAID Array 110 Subsystem
          and TCQ support.

    1.2.1 Order of Installation

          The operating system and other components must be installed
          in the following order.

          For an Update

          1. Version V5.5-2 of the OpenVMS VAX operating system (if
             you are not already running this version)

          2. OpenVMS VAX Version 5.5-2H4 update

          3. RAID Utilities (if you purchased that product)

          4. Any new versions of layered products containing SCSI
             class drivers

          1.2 StorageWorks RAID Array 110 Subsystem and TCQ Release Notes


              For an Installation

              1. OpenVMS VAX Version 5.5-2H4 remastered kit

              2. RAID Utilities (if you purchased that product)

              3. Any new versions of layered products containing SCSI
                 class drivers

        1.2.2 Avoiding Multiple Versions of Device Drivers

              Device drivers normally reside in a directory identified
              by the system logical name SYS$LOADABLE_IMAGES, from which
              the drivers are loaded when the system is booted. Note,
              however, that this logical name translates to a two-element
              list of directories that are searched in the following
              order:

              1. SYS$SPECIFIC:[SYS$LDR]

              2. SYS$COMMON:[SYS$LDR]

              The OpenVMS installation procedures always place drivers
              in the SYS$COMMON:[SYS$LDR] directory, which is the
              directory searched after the SYS$SPECIFIC:[SYS$LDR]
              directory. Therefore, if you (or another privileged
              user) have copied a different version of a driver to the
              SYS$SPECIFIC:[SYS$LDR] directory (the directory searched
              first), that version of the driver will continue to be
              used instead of the new version that is copied to the
              SYS$COMMON:[SYS$LDR] directory during the installation.

              To avoid this problem, check the SYS$SPECIFIC:[SYS$LDR]
              directory before you install a new device driver to make
              sure there is not another version of that driver. If there
              is, delete or rename that file before installing the new
              version.

        1.2.3 Third-Party Driver Restrictions

              Third-party drivers are commonly used to support devices
              other than disks and tapes (such as scanners). If you are
              not sure whether or not your system contains any third-
              party SCSI devices, contact your system manager.

                           OpenVMS VAX Version 5.5-2H4 Release Notes 1-11






    OpenVMS VAX Version 5.5-2H4 Release Notes
    1.2 StorageWorks RAID Array 110 Subsystem and TCQ Release Notes


          If you do use third-party drivers, note the following:

          o  If you plan to use the DEC SCSI TCQ Driver Kit for
             OpenVMS VAX Version 1.0 product in conjunction with
             a third-party product using SCSI class drivers or a
             Digital Layered Product with SCSI class drivers (or
             both), you must obtain a version of that product that is
             compatible with DEC SCSI TCQ Driver Kit for OpenVMS VAX
             Version 1.0. (Contact your local Digital Representative
             to see if the appropriate version of the product is
             available.)

          o  Due to the changes in the driver data structures, any
             third-party SCSI drivers will require recompilation
             against this kit. If you connect existing third-party
             SCSI devices without first recompiling them, your system
             will display the status of those devices as "Offline".

    1.2.4 Specifying Logical Unit Numbers

          When specifying a logical unit number (LUN), note the
          following:

          o  The LUN is an encoded three-bit identifier for a
             physical or virtual device, in the range of 0-7 and
             should not be confused with the SCSI-ID. For example, a
             device name of DKA100 identified as follows:

             -  DK is the device code of the boot device.

             -  A is the boot device controller designation.

             -  1 is the SCSI ID value.

             -  0 (which follows the SCSI ID value of 1) is a
                placeholder value that is always zero.

             -  0 (the last value in the device name) is the LUN.

          o  Booting an OpenVMS VAX system from other than logical
             unit 0 (LUN0) is not supported. Boot devices are
             required to be at logical unit 0. Other logical units
             (LUN1-LUN7) can be used as data storage devices.

          o  Digital strongly recommends that you retain a LUN of
             0 on the StorageWorks RAID Array 110 Subsystem device
             because the console expects to see a LUN 0 for all its
             disk devices. If a device does not have a LUN 0, it
             will not be identified and sized after you enter the

                 be designated "Offline" by the OpenVMS VAX operating
                 system.

                 See the DEC RAID OpenVMS VAX Utility Release Notes and
                 Installation Guide for a description of how to re-create
                 LUN 0.

        1.2.5 Booting Not Supported for TURBOchannel Devices

              VAX workstations running the OpenVMS VAX operating
              system do not provide support for system booting from
              a TURBOchannel device. You cannot, therefore, boot from
              a StorageWorks RAID Array 110 Subsystem connected to a
              TURBOchannel-SCSI adapter.

        1.2.6 SHOW DEVICE Does Not Display Capacity

              On some VAX systems, the capacity of the StorageWorks RAID
              Array 110 Subsystem is not displayed after you enter the
              following console command:

              >>> SHOW DEVICE

              Instead the capacity displays as "...". (This is due to
              the current settings for spin up time in the EEPROM of the
              StorageWorks RAID Array 110 Subsystem.)

              If you reenter the SHOW DEVICE command, the correct
              capacity will be displayed. This will be corrected in an
              update to the DEC RAID OpenVMS VAX Utility Kit.

        1.2.7 Mounting a Disk in a Host-Based Shadow Set

              To mount a disk in the StorageWorks RAID Array 110
              Subsystem in a Host-Based Shadow set, you must use the
              /OVERRIDE=NO_FORCED_UNIT qualifier with the MOUNT command.

              The StorageWorks RAID Array 110 Subsystem does not support
              the READ/WRITE LONG SCSI commands which are necessary for
              implementing the FORCED ERROR function in SCSI. Without
              FORCED ERROR, you must override that check by the shadowing
              driver.

    1.3 DEC LAN Device Driver Release Notes

          This section describes the release information for the
          DEC LAN Device Driver support contained in the OpenVMS VAX
          Version 5.5-2H4 operating system.

          This release provides support for the DEC FDDIcontroller
          /Q-bus and DEC FDDIcontroller/TURBOchannel controllers.
          The QIO interface to these devices is the same as that
          described for the DEC FDDIcontroller 400 (DEMFA) in Chapter
          6 of the VMS I/O User's Reference Manual: Part II; however,
          the DEC FDDIcontroller/Q-bus device type is DT$_FQ_DEFQA
          (58 decimal) and the DEC FDDIcontroller/TURBOchannel device
          type is DT$_FC_DEFTA (57 decimal).

          The following sections contain additional information about
          DEC LAN device driver support.

    1.3.1 DEC FDDIcontroller/Q-bus Controller

          The FQDRIVER supports the DEC FDDIcontroller/Q-bus (DEFQA).
          Its device name is FQcu, where c represents the controller
          and u represents the unit number (for example, FQA0).

          Using DECnet-VAX for OpenVMS with the Controller

          To use DECnet-VAX for OpenVMS with the DEC FDDIcontroller
          /Q-bus on the OpenVMS VAX Version 5.5-2H4 operating system,
          you must define a logical once per system boot procedure
          before invoking NETCONFIG.COM or STARTNET.COM command
          procedures. Use the following DCL command to define the
          required logical:

          $ DEFINE/SYSTEM FXc0 FQc0

          In this command, c represents the controller (for example,
          FQA0). Note that this logical is required only when using
          DECnet-VAX for OpenVMS on the OpenVMS VAX Version 5.5-2H4
          operating system.

          The NCP LINE and CIRCUIT name for the Q-bus controller is
          as follows:

          MFA-<controller number>

          (For example, MFA-0 for FQAn.)

              Using DECnet/OSI for OpenVMS with the Controller

              To use DECnet/OSI for OpenVMS with the DEC FDDIcontroller
              /Q-bus on the OpenVMS VAX Version 5.5-2H4 operating system,
              you must define a logical in SYS$MANAGER:SYCONFIG.COM
              before invoking NET$CONFIGURE.COM or NET$STARTUP.COM
              command procedures. Use the following DCL command to define
              the required logical:

              $ DEFINE/SYSTEM FXc0 FQc0

              In this command, c represents the controller (for example,
              FQA0). Note that this logical is required only when using
              DECnet/OSI on the OpenVMS VAX Version 5.5-2H4 operating
              system.

              Defining the logical in SYS$MANAGER:SYCONFIG.COM makes the
              definition permanent.

        1.3.2 DEC FDDIcontroller/TURBOchannel Controller

              The FCDRIVER supports the DEC FDDIcontroller/TURBOchannel.
              Its device name is FCcu where c is the controller and u is
              the unit number (for example, FCA0).

              The NCP LINE and CIRCUIT name for the DEFTA controller is
              as follows:

              FZA-<controller number>

              (For example, FZA-0 for FCAn.)

              This chapter describes how to prepare your system for an
              update, how to use the update procedure, and how to perform
              postupdate tasks.

                ________________________ Note ________________________

                Before you update your system, be sure you have
                reviewed the update and installation guidelines in
                Section 1.1.1.

                ______________________________________________________

        2.1 Preparing Your System

              Before you install the kit, perform the following tasks:

              1. Make sure that your system is running OpenVMS VAX
                 Version V5.5-2.

              2. Using OpenVMS VAX Version V5.5-2 standalone BACKUP, make
                 an image backup copy of the system disk.

                 A system failure at a critical point in the update
                 procedure might corrupt the contents of the system disk.
                 Therefore, it is important that you back up the system
                 disk at this time so that you always have a working
                 copy.

                 For more information about backing up your system disk,
                 see the upgrade and installation supplement for your VAX
                 computer.

              3. Prepare the system disk. Make sure that you have at
                 least 26,000 blocks of free space on the system disk for
                 the update.

                              Updating to OpenVMS VAX Version 5.5-2H4 2-1






    Updating to OpenVMS VAX Version 5.5-2H4
    2.1 Preparing Your System


          4. Make sure your system has a high enough quota for
             the size of the system working set (the value of the
             SYSMWCNT parameter). The system requires a minimum quota
             of 1900.

             To determine the value of the SYSMWCNT parameter, enter
             the following command:

             $ WRITE SYS$OUTPUT F$GETSYI("SYSMWCNT")

             If the number returned is less than 1900, modify
             the system parameter SYSMWCNT. For example,
             if you must increase SYSMWCNT by 200 to reach
             a quota of 1900, add the following line to
             SYS$SPECIFIC:[SYSEXE]MODPARAMS.DAT:

             MIN_SYSMWCNT = 200 + current-value

          5. Make sure your system has enough free global pages to
             install the update kit. The system requires a minimum of
             30,000 free global pages.

             To determine the number of free global pages, enter the
             following command:

             $ WRITE SYS$OUTPUT F$GETSYI("FREE_GBLPAGES")

             If the number returned is less than 30,000, modify
             the system parameter GBLPAGES. For example,
             if you must increase GBLPAGES by 64 to reach
             30,000 global pages, add the following line to
             SYS$SPECIFIC:[SYSEXE]MODPARAMS.DAT:

             MIN_GBLPAGES = 64 + current-value

          6. Change the values of the system parameters you modified
             by running the AUTOGEN.COM procedure as follows:

             $ @SYS$UPDATE:AUTOGEN GETDATA REBOOT

             For complete information about using AUTOGEN, see the
             OpenVMS System Manager's Manual.

          7. To make sure that the SYSTEM account has sufficient
             quotas and limits, use the OpenVMS Authorize utility as
             follows:

             a. Enter the following commands:

                    $ SET DEFAULT SYS$SYSTEM
                    $ RUN AUTHORIZE
                    UAF> SHOW SYSTEM

                 b. Compare the SYSTEM account's limits and quotas to the
                    following minimum required values:

                    _____________________________________________________
                    Quota_Name______________________Minimum_Values_______

                    Open file quota (FILLM)                100

                    Buffered I/O limit (BIOLM)              18

                    Direct I/O limit (DIOLM)                18

                    AST limit (ASTLM)                       24

                    Enqueue quota (ENQLM)                  200

                    Buffered byte quota count            32768
                    (BYTLM)
                    ______________________________________________

                 c. If necessary, adjust the limits and quotas until they
                    are equal to or greater than the required values. You
                    can change each value by entering a command in the
                    following format:

                    UAF> MODIFY SYSTEM/limit=new_value

                    For example:

                    UAF> MODIFY SYSTEM/DIOLM=18

                 d. Exit the OpenVMS Authorize utility by entering the
                    following command:

                    UAF> EXIT

                 e. If you adjust any of the SYSTEM account's parameter
                    or quota values, log out and log in again so that the
                    new values take effect.

              8. Once you are logged in to the SYSTEM account, make sure
                 that you are the only user by completing the following
                 steps:
                 a. Enter the following command to notify current users
                    that they must log out:

                 $ REPLY/ALL/BELL/SHUTDOWN "Log out for Version 5.5-2H4 update."

             b. Enter the following command to prevent nonprivileged
                users from logging in:

                $ SET LOGINS/INTERACTIVE=0

          9. If you want to shut down the DECnet software on your
             system, enter the following commands and then go to
             Section 2.2:

             $ RUN SYS$SYSTEM:NCP
             NCP> SET EXECUTOR STATE OFF
             NCP> EXIT

    2.2 Matching Update Procedures to System Configurations

          Different system configurations require slightly different
          update procedures. The following list indicates the
          possible system configurations and the section to which
          you should refer:

          o  VAXcluster environment (not including mixed-version
             VAXclusters): Section 2.2.1

          o  Mixed-version VAXclusters: Section 2.2.1. In mixed-
             version VAXclusters, only reapply the update to other
             system disks that are running Version V5.5-2.

          o  Mixed-architecture VAXclusters: Section 2.2.1. In mixed-
             architecture VAXclusters, only reapply the update to
             other system disks for OpenVMS VAX systems running
             Version V5.5-2.

          o  Local area VAXclusters with one boot server and two
             system disks: Section 2.2.2

          o  Standalone system: Section 2.3

    2.2.1 Updating VAXcluster Environments

          Use the following procedure to update all VAXcluster
          environments that do not contain mixed versions of the
          operating system.

             ________________________ Note ________________________

             After completing this procedure, all the systems in
             your VAXcluster environment will be running the same

                ______________________________________________________

              1. Make sure that you have prepared your system for the
                 update as described in Section 2.1.

              2. Log in to the SYSTEM account on a node that uses the
                 system disk you are updating.

              3. Shut down all other nodes in the cluster that boot from
                 the system disk.

              4. Apply the update according to the instructions in
                 Section 2.3.

              5. If your VAXcluster environment uses several system
                 disks, repeat steps 1 through 4 in this section for
                 each system disk in the VAXcluster environment.

              When the update is complete, perform the postinstallation
              instructions in Section 2.4.

        2.2.2 Updating a Local Area VAXcluster System with One Boot
              Server and Two System Disks

              To update a local area VAXcluster system with one boot
              server and two system disks, perform the following steps:

              1. Make sure that you have prepared your system for the
                 update as described in Section 2.1.

              2. Log in to the SYSTEM account on the boot server.

              3. Shut down all other nodes in the cluster that boot from
                 the first system disk.

              4. Apply the update to the first system disk, according to
                 the instructions in Section 2.3.

              5. To update the second disk, perform the following steps:

                 a. Log in to the SYSTEM account on a satellite node that
                    boots from the second system disk.

                 b. Shut down all other nodes in the cluster that boot
                    from the second system disk.
                 c. Apply the update to the second system disk, according
                    to the instructions in Section 2.3.

          When the update is complete, perform the postinstallation
          instructions in Section 2.4.

    2.3 Applying the OpenVMS VAX Version 5.5-2H4 Update

          To update the OpenVMS VAX Version V5.5-2 operating system,
          complete the following steps:

          1. Place the OpenVMS VAX distribution media in the drive.

          2. Start the VMSINSTAL command procedure by entering the
             following command:

             $ @SYS$UPDATE:VMSINSTAL VMSU2H4055 MUA0: OPTIONS N

             Where MUA0 is the device name of the source drive that
             holds the OpenVMS VAX distribution media. The OPTIONS
             N portion of the command indicates that you want to
             display the release notes option menu.

             The following example shows the command line you would
             enter if your distribution media (VMS2H4) is loaded on
             a TK50 tape cartridge drive on controller A, with unit
             number 0:

             $ @SYS$UPDATE:VMSINSTAL VMS2H4 MUA0: OPTIONS N

             If you are updating from the InfoServer, the command is
             similar to the following:

             $ @SYS$UPDATE:VMSINSTAL VMSU2H4055 DAD1: OPTIONS N

          3. As the update procedure begins, VMSINSTAL displays
             messages similar to the following:

                     VAX/VMS Software Product Installation Procedure V5.5

             It is 8-JUL-1993 at 13:30.

             Enter a question mark (?) at any time for help.

             * Are you satisfied with the backup of your system disk [YES]?

             If you backed up the system disk, press the Return key
             and go to step 4.

             If you have not yet backed up the system disk, do the
             following:

             a. Enter NO and press the Return key. VMSINSTAL returns
                to DCL level to permit you to perform the backup.

             b. Back up the system disk.

                 c. When the backup is complete, restart the update
                    procedure at step 1 in this section.

              4. The procedure displays the following message (in the
                 example, MUA0 is the name of the source drive):

                 Please mount the first volume of the set on MUA0:
                 * Are you ready?

                 Make sure the distribution media is in the correct
                 drive, and enter YES.

              5. VMSINSTAL continues with the following display:

                 %MOUNT-I-MOUNTED, VMSU2H4 mounted on MUA0:
                 The following products will be processed:

                 %VMSINSTAL-I-RESTORE, Restoring product save set A...

              6. With OPTIONS N selected, the procedure then displays the
                 following message:

             Release notes included with this kit are always copied to SYS$HELP.

             Additional Release Notes Options:

          7. The procedure displays the following messages:

    %VMSINSTAL-I-RELMOVED, Product's release notes have been moved to SYS$HELP.
    * Do you want to purge files replaced by this installation  [YES]?

    * Do you have any SCSI Class Drivers not supplied with the OpenVMS
    *       VAX operating system installed (eg: DEC IEZ11) [YES]?

    As part of this product's postinstallation procedure, all SCSI Class Drivers
    not supplied as part of the OpenVMS operating system will need to be
    re-compiled against the new SYS$LIBRARY:LIB.MLB before they can be loaded.

    If you have any SCSI Class drives installed, you may want
    to contact your vendor to obtain a version of the driver
    that is compatible with this kit before proceeding with
    this installation.

    * Do you want to continue [NO]?

          8. If you continue with the installation, the procedure
             displays the following messages:

                To complete the installation of this product, you should reboot
                the system. If it is not convenient to reboot at this time, then
                enter NO to the following question.

                 If you enter NO, the installation procedure will terminate.

       * Will you allow a system shutdown after this product is installed [YES]?
       * How many minutes for system shutdown [0]:
       * Do you want to do an automatic system reboot [YES]?

           Completion of this update requires a system reboot.  This
           procedure will automatically shut down the node being updated.  Any
           other VAXcluster nodes using this system disk should be shut down
           before the installation.

           Please ignore any messages you see at the end of the installation
           from INSTALL concerning the failure to REPLACE an entry. The
           "global page table full" messages accompanying the INSTALL messages
           should be ignored as well.  These messages do not affect the
           installation, and conditions causing them will be corrected on
           reboot.

             * Press RETURN to continue:

              9. After you respond to the questions about shutting down
                 and rebooting the system, the procedure continues with a
                 display similar to the following:

                                       ***********  NOTE **********

        The installation will now check the file identification for the files
        being replaced.  If the identification does not match the OpenVMS
        VAX V5.5-2 identification values expected by this installation,
        there will be additional questions before the installation can continue.

                 * Press RETURN to continue:

                     Now checking the file identification.

        During this phase, if the procedure finds files (library
        or image) with file identifiers that do not match,
        the system displays additional messages. In the the
        following example, the procedure finds that the image
        file PKCDRIVER.EXE has a file identifier that does not
        match:

        The image identifier for PKCDRIVER.EXE supplied with OpenVMS VAX V5.5-2
        is X-9A5.  The image identifier for PKCDRIVER.EXE on the current system
        disk is X-13.   If the update continues PKCDRIVER.EXE will be replaced
        on your system.

        * Do you want to continue the update: [NO]?

        If you are satisfied the file identifier is correct for
        the file listed in the message, enter YES and press the
        Return key. Otherwise, enter NO, press the Return key,
        and contact your local Digital Representative. (See the
        release note in Section 1.1.2.)

              10.Next, the procedure displays the following messages:

                    No more questions will be asked ...

                    Now applying the updates ...

                        (If reapplying the update, ignore any ECOSET messages,
                        and the subsequent NOFILE messages.  These are normal
                        and simply mean that the fix has already been applied.)

                     A list of these updates will be placed in file
                     SYS$UPDATE:VMSU2H4055.TXT at installation completion.

                                    2.4 Tasks to Perform After the Update


        2.4 Tasks to Perform After the Update

              After you apply an update to your system, Digital
              recommends that you perform the following tasks:

              o  After the update is complete, set the correct date and
                 time, as follows:

                 -  Use the following command to set the time in a
                    nonclustered node:

                    $ SET TIME = 13-JUL-1992:11:22:00

                 -  Use the following commands to set the time in a
                    VAXcluster:

                    $ RUN SYS$SYSTEM:SYSMAN
                    SYSMAN> SET ENVIRONMENT/CLUSTER
                    SYSMAN> SET PROFILE/PRIVILEGE=(LOG_IO,SYSLCK)
                    SYSMAN> CONFIGURATION SET TIME 13-JUL-1992:11:22:00
                    SYSMAN> EXIT

                 Refer to your system management manuals for more
                 information about how the operating system maintains
                 the date and time and how to adjust those settings (for
                 example, to allow for daylight-saving time).

              o  If you want a listing of the images replaced by this
                 update, you can print the following file:

                 $ PRINT SYS$UPDATE:VMS$SPECIAL_VMSU2H4055.DAT

              o  Display the free block count on the system disk by
                 entering the following command:

                 $ SHOW DEVICE SYS$SYSDEVICE:

              o  After you have rebooted the updated system disk and any
                 nodes that use the updated system disk (otherwise, do
                 not perform this next procedure until you have done so),
                 use the VMSU2H4055-PURGE.COM command procedure to purge
                 files that the update procedure could not purge. For
                 example, to purge files produced by the update, enter
                 the following command:

                 $ @SYS$UPDATE:VMSU2H4055-PURGE

                 You can use the OpenVMS VAX Analyze/Disk_Structure
                 Utility to determine whether the update procedure purged
                 files completely.
