Determining the SCSI ID
Before you configure your system to support an HP Ultrium drive, you need to determine which
SCSI ID to use. IDs must be unique for each device on attached to the SCSI bus.
1. Use the
modinfo
command to identify SCSI controller drivers installed on the system:
% modinfo | grep "HBA Driver"
This will produce output similar to the following:
106 780a0000 102b3 50 1 glm (GLM SCSI HBA Driver)
110 780b4000 1272c 228 1 qus (isp10160 HBA Driver)
For the adapter to which the new tape drive is attached, you will need to determine what
SCSI IDs are already used.
2. Determine the SCSI IDs of the existing devices attached to the SCSI controller:
For all adapters:
% dmesg | egrep ".*xxx.*target" | sort | uniq
where
xxx
= the type of adapter (
esp
,
glm
,
fas
,
qus
or
isp
), as appropriate.
For example, for an ESP-based adapter:
% dmesg | egrep ".*esp.*target" | sort | uniq
This produces a list similar to:
sd0 at esp0: target 0 lun 0 sd6 at esp0: target 6 lun 0
This indicates that SCSI IDs 0 and 6 are used for existing devices. SCSI ID 7 is generally
used for the adapter itself. In this situation, you would use a SCSI ID from 1 to 5 for the new
tape drive.
