What is the device file for your backups? You probably don't have a /dev/rmt/c2t3d0BEST.

<<

may be your point the wrong tape device file

ioscan -fnC tape --> output needed to make suggestion

See /var/sam/log/br_log for details --> can also post this information

>>>tape 1 0/1/1/0.2.0 stape NO_HW DEVICE TANDBERGTS800 <<

Problem could be NO_HW DEVICE found

# insf -e (install device files)

# ioscan -fnC tape (ioscan again the tape)

Thanks,

what do you specfiy your tape path for make_tape_recovery ..?

Thanks,
Johnson

Re: unable to take backup

Md. Farhan A Azam — Fri, 12 Dec 2008 05:58:22 GMT

Hi,
IGNITE through /dev/rmt/0mn

Re: unable to take backup

Md. Farhan A Azam — Fri, 12 Dec 2008 06:03:50 GMT

Hi,

IGNITE command was

#make_tape_recovery -Av

bydefault its taken /dev/rmt/0mn

Re: unable to take backup

Johnson Punniyalingam — Fri, 12 Dec 2008 06:08:54 GMT

ok , make sense,

so while choosing you backup device via sam under the Scanning system hardware for backup devices... are you choosing /dev/rmt/0mn ..?

0/1/1/0.3.0 which is pointing to /dev/rmt/0mn

Thanks,
Johnson

Re: unable to take backup

Md. Farhan A Azam — Fri, 12 Dec 2008 06:26:04 GMT

Hi,

I tried with with both /dev/rmt/0mn & /dev/rmt/c2t3d0BEST, but getting same error every time.

try with below options.

1. Try Uninstall drivers and again install it.

2. Install latest patch of STAP and karnel.

3. Try With HP LTO-3 to take backup

Assalam-Alai-Kum Farhan,

Before jumping to any conclusion plz cross verify the basic things like:

1-Check the write protected button over the tape that might be preventing the tapedrive to write anything over the tape.

2- Use insf -eH h/wpath (sometimes it is beneficial to make device specialfiles using the H/W of the specific device instead for all the devices.

3-mt -f /dev/rmt/0mn stat (check status of the tape whether it is ok or not)

4- If it is external tape drive then plz check for Port Terminator is connected properly.Sometimes it also causes problem.

And at last but not least please try out with command line instead of using the SAM.

#fbackup -f /dev/rmt/0mn -v -u0g -I indexfile

I have used this command once for testing whether this command is able to take the backup of multiple partition or not,we got success at that time.And since we used this command thru command line.
But we are usually taking backups using DataProtector.
