make_tape_recovery error

[Jeff Hagstrom]

ERROR: This is not a no rewind device file.
ERROR: Check tape device failed.
CMD: make_tape_recovery -a /dev/rmt/1m -I -v -x inc_entire=vg00

What do the error messages mean?

It means just what it says. You didn't use the no-rewind tape device file.

Instead of /dev/rmt/1m use /dev/rmt/1mn

That will allow make_tape_recovery to work.

Hi Jeff,

use the no rewind device
/dev/rmt/1mn
for make_tape_recovery.

That's it. Else your command's fine.

Rgds,
Jeff

make_tape_recovery -a /dev/rmt/1mn -I -v -x inc_entire=vg00

Note the n in /dev/rmt/1mn

Hi,

Just FYI - The reason make_tape_recovery needs a no rewind tape device is that ignite creates the tape in a couple of stages.
First it creates the mini system and install program (the ability to boot, run the install program and some other neat features), then it generates a pax archive of your file system.

If it were to use the 1m device file, it would copy the mini system to tape, then rewind itself and write the pax archive right over the top of the mini system, thus making the tape unbootable and for all intents and purposes not usable as a bootable recovery.

HTH,
Kel
