Configuring The Device Files - HP 330834-B21 - StorageWorks Ultrium 460 Tape Library Drive Module Technical Reference Manual

Configuring the Device Files

30 Sun Systems, Solaris (SunOS 5.x)
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.
Determine the device file by typing:
% ls -l /dev/rmt/*m | grep "st@X"
where is the SCSI ID. Identify the line for the tape drive. For example, if the
X
drive was at SCSI ID 2, look for the line containing "
as follows (but on a single line):
lrwxrwxrwx 1 root root 63 Mar 1 00:00 /dev/rmt/0m
../../devices/sbus@1f,0/espdma@e,8400000/esp@e,
8800000/st@2,0:m
Here you could use
/dev/rmt/0m
file.
Only if necessary, make the following file modifications to enhance
performance:
