determining the SCSI id
Before you configure your system to support your new HP Surestore Ultrium drive,
you need to determine what SCSI ID to use. The SCSI ID must be unique for each
device attached to the SCSI bus. To list the existing devices, use the following
command:
% hinv -v | grep SCSI
This will produce output similar to the following:
Integral SCSI controller 0: Version WD33C93B, revision D
Disk drive: unit 1 in SCSI controller 0
In this, “unit X” indicates the SCSI ID. Review the list of existing SCSI IDs and
choose an available ID to assign to your new tape drive.
configuring the device files
To install the HP Surestore drive on a Silicon Graphics system running IRIX, you will
need to modify the kernel configuration file.
If you want
tar
to default to short block transfers, change the
512*512
in your
tpsc
or
scsi
HP entry to
128*512
(128-kilobyte blocks) or, better still,
64*512
(64-
kilobyte blocks).
1
Open the kernel configuration file
/var/sysgen/master.d/scsi
, for IRIX 6.2 and
later, with a text editor.
2
Find the following entry in the kernel configuration file and copy it to a new location in
the file where you can edit it as appropriate for your tape drive:
For IRIX 6.2:

Recompile the kernel by running
autoconfig
and then reboot the system. When you
reboot, the device files for the Ultrium drive will be created automatically.
The following device files will be created in
/dev/rmt
:
tps0d3
tps0d3c
tps0d3cnr
tps0d3cnrns
tps0d3cnrnsv
tps0d3cnrs
tps0d3cnrsv
tps0d3cnrv
tps0d3cns
tps0d3cnsv
tps0d3cs
tps0d3csv
tps0d3cv
tps0d3nr
tps0d3nrns
tps0d3nrnsv
tps0d3nrs
tps0d3nrsv
tps0d3nrv
tps0d3ns
tps0d3nsv
tps0d3s
tps0d3sv
tps0d3v
tps0d3stat
These device file names can be interpreted as follows:
Device Name Function
c
Compression
nr
No rewind on close
v
Device supports variable block sizes
ns
Device does not byte-swap
s
Device does byte-swap
stat
Allows the device to be used when one of the other device
files specifying the same physical device is already opened
For example, the device file
tps0d3
indicates a device on controller card 0 at SCSI ID 3,
and the device file
tps0d3nrv
indicates a device on controller card 0 at SCSI ID 3 that
does not rewind on close and supports variable block sizes.
Once the device files have been created, you should confirm that your new tape drive is
working properly. See
Verifying Installation
.
