Steven,

1) Do you have a tape device at that address - check with ioscan -kfnCtape?

2) Are you using a new tape?

3) Has the drive been cleaned recently?

Pete covered all grounds.

Try to keep another tape and see if it works.

mt -f /dev/rmt/0m rew

Will return a return code ($?) of Not Zero if there is no tape in the drive or the drive is not ready.

Best done before all tape backup commands within a script.

Share and Enjoy! Ian

Hi Steven,

That's your next best bet. Mediainit and see if it works.

mediainit /dev/rmt/0m

If it fails, clean the drive and try again.

Steven,

It might be a hardware problem with the drive. Do you have a support contract?

I do...but I want to exhausted all the options before I called them...with your help...

How do I check on the hardware level on what it is supposed to be?

Have you checked the basics on the tape drive? Is it powered up? Are the SCSI cables plugged in? Is it properly terminated?

Have you tried a different tape?

If all else fails, place your hardware call.
