tar error message

Fordie — Fri, 25 Jan 2008 10:25:08 GMT

All,
I have finished completing a backup to tape and I now wish to check the contents on it.
Using the command 'tar tvf /dev/rmt0m' I receive the following error;
'Tar: blocksize = 2
directory checksum error'.
Any help greatly appreciated

This is an Ignite tape, right?

Use

# mt -f /dev/rmt/?mn rew
# mt -f /dev/rmt/?mn fsf 1
# tar -tvf /dev/rmt/?mn

What is your platform ?
For Itanium, you need fsf 22
For PA-RISC, there is the /opt/ignite/bin/copy_boot_tape command to check the usability of an ignite tape.

Another option:

/opt/ignite/bin/check_tape_recovery

see

man check_tape_recovery

for details.
