Hi,
do you know what software was used to write the tape (dd, fbackup,tar..)?
You can load the tape into a tapedrive and then try SAM to do an recover.
Alternatives are dd (man dd) or pax.

Hi Vu,

On HP-UX, the backup can be done on several ways. With basic HP-UX commands (eg. tar, fbackup, dd, cpio) OR by backup software management (dataprotector, netbackup, legato).

So tt's a good way to ask from the person who gave you that tape, about what's the method that he/she use to backup the data into the tape. That's the easy one and safely.

To make it safe, make sure the tape only for read only. And here is the command to check the content of the tape (eg. the tape device file : /dev/rmt/0m) :

- with tar command :
# tar tvf /dev/rmt/0m

- with fbackup/frecover command :
# frecover -rNv -f /dev/rmt/0m

- with cpio command :
# cpio -ictv < /dev/rmt/0m

And if the backup from make_tape_recovery command, here is to check the content :

Skip over the first image with mt command
# mt -f /dev/rmt/0mn rew
# mt -f /dev/rmt/0mn fsf 1

Verify the contents of the tar image:
# tar tvf /dev/rmt/0m

Hope this information can help you.

Cheers,
AW

Hi QVU ,

If it is in tar format ,You can check that with ,

# tar -tvf /dev/rmt/0mn

where /dev/rmt/0mn is the device name , can be found from ioscan -fnC tape,

Raj.
