Check the write protect tab on the tape.

Thats what it was last time I got this message.

Hi:

You need to specify a no-rewind tape device (e.g. 0mn). Ignite write a bootable LIF file and then the actual 'pax' ('tar'-like) archive of files.

Regards!

The error is just what it says. The tape device you specified is not a no-rewind device. You must specify /dev/rmt/0mn (the n on the end of the device name indicates that it is a no-rewind device) in you make_tape_recovery command.

You must do this becuase make_tape_recovery creates a boot area at the beginning of the tape, the puts the pax archive of your data after the boot area. If you don't have a no-rewind device, and make_tape_recovery didn't error out, your tape would be useless. It would create the bootable area at the beginning of the tape, then rewind and create the pax archive and overwrite the boot area.

Hello!

You should specified a no-rewind tape device
that the make_tape_recovery will work
and create tapa that will work in the end.
