Solaris

Hi all,
I have solaris 10 sparc running and working very well
but i have problem with external SCSI tape drive DAT 72 problem
it seems to me the tape drive is manufactured by SUN microsystems
when i ran ls -l /dev/rmt/0
it reveals the following output

Code:

bash-3.00#  mt -f /dev/rmt/0 status
/dev/rmt/0: No such file or directory

when i ran ls -l
it reveals the following output

Code:

ls -l /dev/rmt/0
lrwxrwxrwx   1 root     root          43 Sep 20  2006 /dev/rmt/0 -> ../../devices/pci@8,600000/scsi@1,1/st@3,0:

it seems to me everything is okay
SCSI cable is connected properly to Tape device and to server as well
the tape has SCSI termination dongle as well and connected properly to Tape device as well
any ideas would be a great assist
Thanks in advance

A tape drive as with any SCSI device has to be set to a bus address that is not the same as any other device on the same SCSI bus, I hope someone else can confirm that tape device are usually set to target address 3 or 4. While down at OBP's ok prompt you should see the tape drive listed when you run a:
ok> probe-scsi-all
once you can see it listed there then do a reconfiguration boot:
ok> boot -r
to get Solaris to "see" the tape drive, and as you have already suggested running:
# mt -f /dev/rmt/0 status
or
# mt -f /dev/rmt/1 status
is a good test for the tape once running Solaris.

thanks
okay i will try your hint and post here again

thanks Tony for your quick helpful replies
sorry for inconvenience
the instance number for external tape is 1 not 0

it works now very fine

Code:

bash-3.00# mt -f /dev/rmt/1 status
HP DAT-72 tape drive:
   sense key(0x6)= Unit Attention   residual= 0   retries= 0
   file no= 0   block no= 0
bash-3.00#
