                  information  for  all  IDA  controllers in the system is
                  displayed on the screen and the menu is not seen; return
                  to  step  2.   In addition, all information is logged in
                  the file /usr/bin/compaq/diags/ida/ida_file.

         Menu Options
            The following provides information on each of the menu
            options:

            Identify Controller

            Use this option to identify the configuration of the IDA
            controllers.  It displays the following information:

             Sense Drive Monitor & Performance Threshold Violation Status

             This option is used  to  return  the  drive  threshold  status
             information for each drive attached to the controller.

                         Sense Drive THreshold Violation Status: /dev/***

             If  the  drive  threshold(s)  has(have)  been  exceeded,   the
             following messages will be displayed:

                         Drive threshold(s) has(have) been exceeded for device:
                         /dev/***, slot number: *
                         drive: *

             The controller has detected drive(s) that exceeded one or more
             factory  preset  thresholds for performance degradation.  Many
             Compaq  high-performance   drive   array   hard   drives   are
             ``stamped'' by the drive manufacturer with minimum performance
             characteristics.  As a result of normal  wear  and  tear,  the
             performance  of  a  hard  drive may gradually deteriorate.  If
             certain thresholds are exceeded, the drive may not perform  to
             specified  levels,  and  may  be  subject  to hardware failure
             sometime in the future.  Drives that exceed  these  thresholds
             are  considered ``failed,'' although true catastrophic failure
             has not yet occurred.

             If the drive threshold(s) has(have)  not  been  exceeded,  the
             following messages will be displayed:

                         Drive threshold(s) has(have) not been exceeded for device:

            Possible status messages are:

            Enabled
                  Posted write operations  are  currently  configured  and
                  enabled.

            Temporarily Disabled
                  The  posted  write  operations  have  been   temporarily
                  disabled.   See  the Disable Code field to determine the
                  reason.

            Permanently Disabled
                  The  posted  write  operations  have  been   permanently
                  disabled.   See  the Disable Code field to determine the
                  reason.

            Posted Writes Drive Bit Map
                  Each bit in this map corresponds to a respective logical
                  drive  number.   When  a  bit  is set to 0, posted write
                  operations are enabled for that logical drive.  A  value
                  of 1 indicates that posted write operations are disabled
                  for that logical drive.  Logical  drives  that  are  not
                  configured have a value of zero.

            Posted Writes Logical Drive ID(s)
                  The  logical  drive  ID(s)  that   have   posted   write

                  Kbytes of available Array Accelerator  memory  that  has
                  been reserved for the read cache.  Since read caching is
                  not supported, expect a value of zero here.

            Kbytes for Posted Write Memory
                  Kbytes of available Array Accelerator  memory  that  has
                  been  reserved  for posted write operations.  Since data

                   for  posted  write  operations  is  saved  in  duplicate
                   (mirrored), the maximum amount of posted write data that
                   can be stored here is actually no greater than  half  of
                   the value of this field.

             Disable Flag
                   A value of 1 indicates that configuration data does  not
                   exist  for  the  daughter board.  A value of 0 indicates
                   the presence of configuration data.

             Disable Code
                   The  value  of  this  field  should  be  referenced   to
                   determine  the  reason that posted write operations were
                   either temporarily or permanently disabled.   The  value
                   of  this  field  is  only  meaningful  if  posted  write
                   operations  are  either   temporarily   or   permanently
                   disabled.  Possible Disable Code messages are:

             Bad Configuration
                   The Array Accelerator seems to have been configured  for
                   a different IDA controller.  The configuration signature
                   in the posted write memory does not match the one stored
                   in the configuration data stored on the drives.

             Low Battery Power
                   Posted write operations have been disabled because  less
                   than 75% of the battery packs (currently 4 total battery
                   packs) are at the sufficient voltage level.

            No Resources Available
                  The  controller  does  not  currently  have   sufficient
                  resources to perform posted write operations.

            Board Not Connected
                  Array Accelerator is not attached to the controller.

            Bad Mirror Data
                  Data was found at reset  initialization  in  the  posted
                  write  memory,  however,  the  mirror  data compare test
                  failed resulting in the data being  marked  as  invalid.
                  Data loss could possibly occur.

            Read Failure
                  Soft errors occurred when trying to read the  same  data
                  from  both  sides  of  the mirrored posted write memory.
                  Data was lost.

            Write Failure
                  Data could not be written to the posted write memory  in
                  duplicate because of parity errors.  Data was not lost.

            Config. Command Issued
                  A BMIC set configuration  command  was  issued.   Posted
                  write operations remain disabled until a BMIC set posted
                  write command is issued once again.

            Accept Media Exchange

            This option is for the  Compaq  SMART  SCSI  Array  Controller
            only.   In  a  No  Fault Tolerance (RAID 0) configuration, the
            Accept Media Exchange command causes the SMART  Controller  to
            set the state of the logical drive to OK after a logical drive
            has failed and the failed physical drives have  been  replaced
            through hot-plug exchanges.

       ida_menu(1M)                                            ida_menu(1M)


             After you have replaced the drives through a hot-plug exchange
             a  "Failed" Status will be returned before you select option 2
             of the IDA Diagnostic Menu.  After this command is issued, the
             "Failed"  status  is  cleared.  If you select the Accept Media
             Exchange command when the logical drive is  not  in  a  failed
             state or has not been exchanged, the command terminates with a
             fatal error.

             When you use this command, the system checks to  determine  if
             the   media   exchange  feature  is  supported  on  the  drive
             controller.  If the media exchange feature is  not  supported,
             the system displays the following message:

                         The "Accept media exchange cmd" is not supported for device: /dev/***
                         Press <Enter> to continue

             When this command  is  issued,  the  system  also   checks  to
             determine  if  more  than one logical drive is configured.  If
             the IDA controller has more than 1 logical drive,  the  system
             displays the following message:

                         Accept Media Exchange: /dev/***
                         Enter logical drive number:

             If you don't know which logical drive has failed, use option 2
             of  the  IDA Diagnostics Menus (Identify Logical Drive Status)
             to find the logical drive that has a "Failed"  status.   Next,
             the system displays the following message:

                         Accept Media Exchange cmd completed.
                         Press <Enter> to continue

             If the logical drive you specified does  not have  a  "Failed"
             status, the system displays the following message:

                         ioctl: Can't accept media exchange for device: /dev/***

             Read Error Log

             This option is used to return logs of previous errors for  all
             drives  in the controller.  This function is only supported on
             SMART Controllers.  The following  information  is  displayed.
             For  complete  descriptions  of this information, refer to the
