Nancy,

I have had the problem 2x this year and I rebooted the 3494 tape library
and the problem went away.  I could not see any "unavailable" or "reado" .
After the reboot of the 3494 tape library I was able to complete
reclamations, migrations, and checkins on the scratch tapes.  Still haven't
figured what causes this.

Thank You,

Nancy,

It's possibly that it is not those tapes that are inaccessable but
rather the tape that holds the same data in the primary pool.  Assuming
these are copypool tapes, if you try to move data or space reclaim and
tsm thinks they are not in the library, it will try to use the
corresponding primary pool tapes.  If they are unavailable for some
reason, you will get this error.  I reccommned running a "q vol
access=unavailable" and reasearch any tapes that might show up in that
query.

I have 3 tape volumes that I cannot access. Anything that accesses the
tape (including Space Reclamation & Move Data) get  errors (different
for
each command) that include "xxxx terminated for volume 999999 -
storage
media inaccessible."

I can't figure out why! It doesn't seem to matter whether the volumes
are
checked into the library or not. (If not, I should get a mount
request.)
Here is the result from a "q vol 99999 f=d" for one of them.

Thanks for any ideas. (TSM server is 4.1.0.0 running on AIX with a
3575
tape library.)
