Hi,

After attaching your tape drive did you check your log messages in which device it was assign.

are you sure it is /dev/st0

or you can check with st1, st2 like....

Check your log files

Hi Syad

Try to check

#dmesg |grep tape

tapedevice like st0, st1 like this

After that
#
#tar -cfv /dev/tapedevice /filepath

To check the List the names of all the files in the archive

#tar -tvf /dev/tapedevice >/tmp/backup_list.txt

#tar -tvf /dev/tapedevice

Tape drive is automatically mount

Hi Guys,

Thanks for the prompt reply..I checked the logs and found no relevent info regarding the tape drive on dmesg and messages.log

Also tried to check other device file name...but the output is the same..

[root@chtosapp output]# mt -f /dev/st0 status
/dev/st0: No such device or address
[root@chtosapp output]# mt -f /dev/st1 status
/dev/st1: No such file or directory
[root@chtosapp output]# mt -f /dev/st2 status
/dev/st2: No such file or directory
[root@chtosapp output]#

Any other ideas?

Regards

Hi,

die Tape driver show up in
# lsmod | grep st

maybe you need to (re-) load the driver:

# rmmod st
# modprobe st
then have a look at dmesg and /proc/scsi/scsi

Hi,
In HP-UX we are chaging in kernel following:

stape = static

There may be some changes in linux...
