NOTE: Only SCSI drives are supported on Solaris.

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
For FAS or ESP devices:
% modinfo | grep "HBA Driver"
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
For example, for an GLM-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 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:
1. In the file
/kernel/drv/st.conf
