Re: ERROR ----- /dev/nrmt0h:No such device or address

Please post output of:

# mt -f /dev/nrmt0h status
# scu show edt
# ls /dev/*rmt*
# file /dev/nrmt0h

Is it internal or external tape drive?
Jumpers are used to set SCSI address and some other parameters (SCSI parity and so on).
Wrong jumper settings can cause the problem

Re: ERROR ----- /dev/nrmt0h:No such device or address

Tape is stuck inside , even pressingf eject doesnot throw it out
Is there any forced operation for this...

output of file /dev/nrmt0h is
character special (9/32771) SCSI#2 SDT-9000
tape#19 (SCSI ID 0)( SCSI LUN #0) offline

ls /dev/*rmt* lists all the devices

I hav chaged some 4-5 tape drives but same kind of problem

wht could be the cause

When you have stuck tapes inside, sometimes pressing the eject button by about 10 seconds, will force the eject, otherwise power off the tape device (if external).

You should call for hardware maintenance.

may I assume, it is external? Some tapes have an emergency switch, which can be pushed after the case has been removed. But other than that it is maintenance as said.
