NAME
       sd - access a SCSI disk drive

SYNOPSIS
       /dev/rpdsk|pdsk/sd (adapname@devicecode (adapaddr[,adapid]),
                         deviceid[, d])

DESCRIPTION
       The sd device driver accesses a Small Computer Systems Interface
       (SCSI) disk drive. The currently supported models on your AViiON
       system are:

       The sd device driver accesses devices via special file nodes in /dev,
       as explained below:

       pdsk|rpdsk     is pdsk for block-special device nodes in /dev/pdsk,
                      or rpdsk for character-special device nodes in
                      /dev/rpdsk

       adapname      is the name of the SCSI adapter; currently supported
                      adapters are cisc, insc, ncsc, dgsc, and hada

       @devicecode   is the adapter's hexadecimal device code, preceded by
                      the @ character

       adapaddr      is the adapter's hexidecimal address

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

       deviceid      is the disk drive's SCSI ID (range 0-7)

       d              is the disk drive's logical unit number (range 0-7 on
                      drives and 0-1F on disk arrays). Omit to accept the
                      default unit number 0.

       The sd interface provides no bad block remapping.

EXAMPLES
       The following statement accesses a character-special SCSI disk:

       /dev/rpdsk/sd(cisc@28(fffff200),1,0)

       The disk drive uses SCSI adapter cisc; the adapter's device code is
       28; the adapter's address is fffff200; the adapter's SCSI ID, not
       specified, is the default ID 7; the disk drive's SCSI ID is 1; and
       the disk unit number is 0.

       The following statement does the same as the above, except that it
       specifies a SCSI adapter ID of 6:

       /dev/rpdsk/sd(cisc@28(fffff200,6),1,0)


FILES
       /dev/pdsk/*
       /dev/rpdsk/*
