Interrogate a make_tape_recovery tape

[Kirk Reindl]

Hi:

Does anyone know of a way to easily interrogate a make_tape_recovery tape using a make_tape_recovery command/switch.

I'd prefer not using using tar plus if I remember tar only shows file listings. I know I can look at the /var/opt/ignite logs, but I what if I didn't have the log.
I was hoping there was something similar to the frecover command
/etc/frecover -V /tmp/index -f /dev/rmt/0m

Thanks,
Kikr

Do you have enough space in any of the filesystem ? - If yes, you can try somethign like this

# ioscan -fnkC tape

# mt -t /dev/rmt/0mn rew

# dd if=/dev/rmt/0mn of=/fs/LIF bs=1024k count=8

# dd if=/dev/rmt/0mn of=/fs/test.tar bs=1024k

This will create two files in /fs directory

LIF = is the lif volume of the boot tape

test.tar = is the tar archive of the system from the recovery tape

If both the above dd commands complete without any IO errors, you can safely assume your recovery tape is good.

Other way would be to use tar not just to list the files but also you can try and restore from tar. by default files are stored using the relative path. So you can just cd to any directory that has some free space and try restoring random files using tar.
