Problem in Internal tape Drive of Netra 20

hi everybody,

I am getting a problem with internal tape drive.

My Netra 20 Server having Solaris 8 in it is online and is busy, and I am unable to shutdown. When I tried to take a backup in tape, error message displayed

"No such Devices or Address"

I went to /dev/rmt directory and deleted everything then ran devfsadm but still get same error.

Can any one of you answer how can I debug what is the problem in tape without shutting down the system, nor taking it to OBP.

Here, is the work I had done.

uid=0(root) gid=1(other)

<a href="mailto:root&#64;scp1" target="_blank">root@scp1</a> # devfsadm

<a href="mailto:root&#64;scp1" target="_blank">root@scp1</a> # mt stat

/dev/rmt/0n: No such device or address

<a href="mailto:root&#64;scp1" target="_blank">root@scp1</a> # exit

Thanking you

Your backup driver can have another target number. Have u check the files under /dev/rmt

first of all delete all the files under /dev/rmt then run devfsadm -vC

and check the files under /dev/rmt.

ls -l /dev/rmt/*

there if u see files such as 1n, 1, 1cbn this means that your backup drivers target 5 and u can access it as mt -f /dev/rmt/1n status.

hope this will solve your problem.

if u can not see any files check the cable.

Orkut:

This original post was eight months ago and they've never returned to any of the Sun-hosted forums, not hardware nor software.The system has probably been repaired.

I don't think your guess that tape drive 0 is target 4 and drive 1 is target 5 would always be true.

Perhaps others can jump in here, but I was always under the impression that tape drive 0 was the first one configured to a system, no matter what the path, drive 1 would be the second tape device, no matter what the path, and so on.

There could be circumstances whereby there is an internal DAT drive on its controller's target 4 then later there is an external tape unipak on its own target 4, etc, etc, etc.

I guess all I'm saying is that the investigation should follow device paths and not the contents of the /dev/rmt folder.
