Determining the SCSI ID
Before you configure your system to support your Ultrium drive, you need to determine which
SCSI ID to use. IDs must be unique for each device attached to the SCSI bus. To list the existing
devices, use the following command:
% lsdev -C |grep SCSI
This will produce output that looks similar to:
scsi0 Available 00-00-0S Standard SCSI I/O Controller
hdisk0 Available 10-60-00-0,0 16 Bit LVD SCSI Disk Drive
rmt1 Defined 00-00-0S-2,0 Other SCSI Tape Drive
The SCSI ID is in the series 00-00-0S-X,0, where X is the SCSI ID. Review the list of existing
SCSI IDs and choose an available ID to assign to the new tape drive.
Configuring the Device Files
To install an HP Ultrium drive on an IBM workstation you will need to create the appropriate
device files for the drive.
NOTE: Do not choose the smit option of “4mm2gb” as the Tape Device Type. This is reserved
for Connor drives. If you use it with HP drives, you will get the error “
Device to be
configured does not match the physical device at the specified connection
location”.
To change to variable block mode, use the following procedure:
1.
If you are using a graphics terminal running X-Windows, then at a Windows terminal, type:
smit tape
If you are using a non-graphics terminal, at the command line type:
% smit -C tape
2. If no device has been configured at this address before, select “add a tape drive” to set
up the address. From the pop-up window, select “
ost” or “Other SCSI tape drive” as the
tape drive you wish to change and choose connection addresses as appropriate.
