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.
