Re: Jaguar tape paths

Bob,

A guy from adsm-l has suggested the use of tapeutil in this form: tapeutil
-f /dev/rmt0 path. It works like a charm. Just in case anyone else runs into
it.

Thanks,
sbzx

What version of the OS is your customer using?

Have you used the 'lspath' command, so see what weights have been assigned
to the pri and alt paths?

You might also ask this question on the adsm-l list, as there are many
users
of AIX and 3592 tape tech there. They will probably ask the same
question,
so be prepared to describe your customers environment in your note.

cheers,
