Hi Again,

This particular tape drive is working fine when attached to another server.
I have tried rmsf and then insf also but no use.

Any ideas as to what shall I do?

Thanx in advance....

Hi RKK,

I hope it is an external tape drive.As it works fine with another m/c means drive is OK.

1. Check the Cable, try changing the SCSI ID, if possible.

2. Run ioscan -fn & insf -e

3. if doesnot work, remove the drive and do ioscan,check status, reattach the device rmeove/recreate deivce files..also check with lssf to ensure that it is Ok.

4. For mostly it looks like the SCSI Terminator that is attached with the device is defective/not present.Pls Check the SCSI Terminatior by swapping from the working one.

HI

try to run this

#mt -t /dev/rmt/2m

and if you want to rewind the tape, use

#mt -t /dev/rmt/2mnb

Hi All,

Now that somehow the ignite is started (tape being detected), its NOT getting completed (HANGED in between). Its showing "SLEEP" in "top" command.
Below is the o/p and all files except one has 600 permission. Its not like this in other servers.

Are you really sure it hangs?

Next messages should be

"* Creation of system archive complete."

It takes some time ... 30min is not too much.

Hi All,

Torsten, it is completed, but can I rely on today's backup????
Whats those errors above?
And why is these file have 600 permission only bcoz everywhere else the permission is 644.
:(
