Introduction
Before you install your tape drive log on to the HP web site, www.hp.com, and download the latest
hardware enablement patch bundle for your operating system. This ensures that you will have the
correct device driver for your tape drive.
Determining the SCSI ID
Before you configure your system to support an HP Ultrium drive, determine what SCSI ID to use. The
ID must be unique for each device attached to the SCSI bus. To list existing devices, use the
following command:
% /sbin/ioscan -f
The output should look similar to the following:
Class I H/W Path Driver S/W State H/W Type Description
=================================================================================
bc 0 root CLAIMED BUS_NEXUS
bc 1 8 bc CLAIMED BUS_NEXUS Pseudo Bus Converter
ba 0 8/0 GSCtoPCI CLAIMED BUS_NEXUS GSCtoPCI Bridge
ext_bus 1 8/0/2/0 c720 CLAIMED INTERFACE SCSI C895 Ultra2 Wide LVD
target 0 8/0/2/0.7 tgt CLAIMED DEVICE
ctl 1 8/0/2/0.7.0 sctl CLAIMED DEVICE Initiator
lan 0 8/0/20/0 btlan3 CLAIMED INTERFACE PCI(10110019) -- Built-in #1
ba 1 8/16 bus_adapter CLAIMED BUS_NEXUS Core I/O Adapter
tty 0 8/16/4 asio0 CLAIMED INTERFACE Built-in RS-232C
ext_bus 2 8/16/5 c720 CLAIMED INTERFACE Built-in SCSI
target 1 8/16/5.5 tgt CLAIMED DEVICE
disk 0 8/16/5.5.0 sdisk CLAIMED DEVICE SEAGATE ST34573N
target 2 8/16/5.7 tgt CLAIMED DEVICE
ctl 2 8/16/5.7.0 sctl CLAIMED DEVICE Initiator
processor 0 62 processor CLAIMED PROCESSOR Processor
memory 0 63 memory CLAIMED MEMORY Memory
After you have installed the new tape drive, you can check it has been attached successfully. From a
shell window (
hpterm/xterm), execute ioscan to display the list of attached devices.
For an HP Ultrium drive, execute the following:
% /sbin/ioscan -f | grep "Ultrium"
The new lines should look similar to the following for a Generation 1 drive, where the 4 in the I
field represents the instance of the SCSI tape driver, not the SCSI ID:
tape 4 2/0/1.5.0 stape CLAIMED DEVICE HP Ultrium 1-SCSI
or, for a Generation 2 drive:
tape 4 2/0/1.5.0 stape CLAIMED DEVICE HP Ultrium 2-SCSI
