Determining the SCSI ID
Before you configure your system to support a DDS-format drives, 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.
For FAS or ESP devices:
% modinfo | grep "SCSI"
This will produce output similar to the following:
104 78032000 12660 33 1 glm (glm SCSI HBA Driver)
This indicates that there a GLM-based SCSI controller on the system. 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, or isp), as appropriate.
For example, for an ESP-based adapter:
% dmesg | egrep ".*glm.*target" | sort | uniq
This produces a list similar to:
sd6 at glm0: target 6 lun 0
This indicates that SCSI ID 6 is used for an existing device. 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.
Driver configuration
NOTE:
Drives should then work well with Solaris without modifications to the kernel, and you are recommended
to try this.
Only if necessary, make the following file modifications to enhance performance:
