contents of recovery file

[John de Villiers]

How would i read the contents of a recovery file ? I tried to tar -tvf it, but i just get a directory checksum error. Same goes for when i try to read it off the tape.

The reason i want to read it is to try to figure out why one of the ignite tapes didnt work during our recent drp testing.

Hi John,

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

# mt -f /dev/rmt/0mn fsf 1

# tar tvf /dev/rmt/0m >> /tmp/list

John,

Could post a bit more info about your hpux version and ignite version ?

Itanium ?

The archive file is gzipped by default.
You must unzip it:

(
cd /var/opt/ignite/recovery/archives/daytona1

gzip -d | tar tvf - 2>&1

) | head

Notice the "-" on the tar -- it specifies STDIN.


OTOH
An ignite boot tape has a boot_lif in front of the archive. You must bypass that before you can get to the archive:

(
export T=/dev/rmt/0m

mt -f ${T} rew
mt -t ${T}n fsf 1

tar tvf ${T} 2>&1

) | head

The "n" on the mt...fsf keeps the tape from rewinding and it stays positioned past the boot_lif, just at the beginning of the tar archive.

Hmmm.
I misread your orig post a little.
When I saw that is was a file, I assumed a 'make_net_recovery'.

A 'make_net_recovery' archive is gzipped by default.

'make_tape_recovery' archive is *not* compressed and must go directly to a tape device.

If you *did* the 'mt fsf 1', be sure that you used the "n" on the tape device name.

>contents of a recovery file
How did you get the archive to disk??
If you got it from the tape, then, again, be sure that you used the "n" on the 'mt fsf 1' .
