For the adapter to which the new tape drive is attached, you need to determine what SCSI IDs

are already used.

2.

Determine the SCSI IDs of existing devices attached to the SCSI controller:
For all adapters:

# d mesg | egrep ".*xxx.* target" | sort | u niq

where xxx = the type of adapter (esp, glm, fas, qus or isp), as appropriate.
For example, for an ESP-based adapter:

# d mesg | egrep ".*esp.* target" | sort | u niq

This produces a list similar to:

sd0 at esp0: ta rget 0 lu n 0 sd6 a t esp0: t arget 6 l un 0

This indicates that SCSI IDs 0 and 6 are used for existing devices. SCSI ID 7 is generally used for

the adapter itself. Here, you would choose a SCSI ID from 1 to 5 for the new tape drive.

Configuring the device files

Determine the device file by typing:

# l s -l /dev/rm t/*m | gr ep "st@X"

where X is the SCSI ID. Identify the line for the tape drive. For example, if the drive was at SCSI ID 2,

look for the line containing “st@2,0”. This might be as follows (but on a single line):

lrwxrwx rwx 1 ro ot root 6 3 Mar 1 0 0:00 /dev /rmt/0m
../../d evices/s bus@1f,0/ espdma@e, 8400000/e sp@e, 880 0000/st@2 ,0:m

Here you could use /dev/rmt/0m (shown underlined above) as the device file.
For optimal performance, ensure that you have the following minimum patch number:

Upgrading to the minimum patch level will ensure that the necessary support for officially supported

drives is included in the driver. You can view your existing patch level using the command

“uname -a”. To access Solaris patch upgrades, you need to set up an Online Account with Sun.
