Hi thank you for your reply.

Please see my replies below.

I assume this is an exit code for success..

> *) Are you using a tape library?
Yes in sequential/stacker mode. Currently ufsdump spans tapes with "L" option.
> *) Do your tapes have bar codes (and your library a bar code reader)?
Yes but not necessary, we have rotating tape sets.

Library with enough tapes for the week. We send them offsite on Monday
after one week of backups, full + differential.

No need for manual intervention with ufsdump as it automatically spans tapes.
> *) What has the operator to do after changing the tape/magazine?
nothing
> *) Can you control your tape library via mtx (or something similar)?
yes, I have experinented with MTX but since ufsdump spans naturally,
it's not needed.
> *) Do you want to interpret SMART results?
not necessarily.

If by this time I cannot write my own script I will take up selling AVON.. : D
I really just need the syntax to make it work and I can run with it.
