NAME
       cisc - Ciprico VME SCSI bus adapter

SYNOPSIS
       cisc([vmebus,][def]) or
       cisc@devicecode([vmebus,]adapaddr[,adapid])

DESCRIPTION
       The cisc adapter allows an AViiON server to access a Small Computer
       System Interface (SCSI) device. The adapter links a host's VME bus to
       a SCSI bus.  The adapter is available with either a single-ended or a
       differential SCSI bus interface.

       To set up this interface, or access a SCSI device via the interface,
       you use the cisc adapter ID in a device driver statement: see st(7)
       and sd(7).

       The first format accepts all default values. The second format
       specifies all values:

        def         is a hexadecimal number (range 0-F), selecting a default
                    device code and VME address for the adapter. Null equals
                    0.

        devicecode is the hexadecimal device code of the adapter preceded
                    by the @ character.

        vmebus     The device name of the parent VME bus to which the cisc
                    controller is attached, such as vme(0) or vme(1).  If
                    this parameter is omitted, a parent bus of vme(0) is
                    assumed, and all subsequent parameters move up one
                    position.  Thus, cisc(3) is equivalent to
                    cisc(vme(0),3).

        adapaddr   is the adapter's hexadecimal VME address.

        adapid     is the adapter's SCSI ID (range 0-7, recommended 6 or
                    7). Omit to accept the default ID 7.

       A cisc adapter having a firmware revision of 11 or greater attempts
       to use the SCSI synchronous data transfer protocol, by negotiating a
       synchronous offset with each device on the the SCSI bus.  If this
       negotiation fails, or if the firmware revision level is less than 11,
       the asynchronous mode is used.

EXAMPLES
       The following statement in a DG/UX configuration file configures a
       SCSI disk with default values, and creates short and long names for
       the disk in /dev/pdsk and /dev/rpdsk:

            sd(cisc(0),*)

       The following statement configures a SCSI tape drive, specifying
       device code 28, VME host address fffff300, adapter SCSI ID 7, tape

       drive SCSI ID 4, and tape unit number 0:

            st(cisc@28(fffff300,7),4,0)

       The statement creates short and long device names for the tape drive
       in /dev/rmt.

       Short device names (0,1,2, and so on) are created arbitrarily
       depending on the sequence of configuration statements in the DG/UX
       system file.
