Hi all,

Having some problems getting a good make_tape_recovery.

Here is the command line:

/opt/ignite/bin/make_tape_recovery -a /dev/rmt/0mn -x inc_cross=/ > ${FILE}

Here is the error:

I/O error
ERROR: /usr/bin/dd if=/var/tmp/uxinstlf.recovery of=/dev/rmt/0mn bs=2k failed
to write LIF onto tape.
ERROR: Failed to generate LIF on tape .

Any ideas?

TIA

Shalom Chrisl,

Bad tape is likely. Could be dirty heads in the tape drive. Could be both.

Could also be the tape drive.

Suggestions:
1) Clean the tape drive using proper procedures.
2) try a different tape.
3) Do a full hardware check and see if the drive is troublesome.

Steven,

It's an external C6364A drive. Do you have an suggestions on how to do hardware diags on it?


I've cleaned the heads and swapped out several tapes.

TIA

Can you write to the tape with tar?

[Ludovic Derlyn]

try with device /dev/rmt/0m

[Pete Randall]

NO!

The make_tape_recovery command requires the no-rewind device: /dev/rmt/0mn.

Sorry about the multi-part answer.

To diagnose your drive, try using the cstm command (man cstm for details). I would guess that the most likely cause is a bad tape or a dirty drive, as Steve pointed out.

"Here is the error:

I/O error"

This could be a bad tape drive (most likely).

Do you have error messages in syslog.log?

Can you write with other tools onto the tape (tar)?

You can use LTT assessment test to test your drive:

Thanks all. The device ate a tape, so I consider the device broken and replaced it. make_tape_recovery now works fine.
