David,

It is physically in the library...i can see it.  Also i can do an audit
vol on the tape on either side of it, and they mount fine.

Yep, it's there...

Status is R/W, one write error.  TSM had marked it R/O after the write
error, but after it passed a R/O audit vol, i updated it to R/W (to see if
it caught another write error).   This is how it all started with this
particular "problem" tape.

The first error was "An I/O error occurred while accessing drive TAPE1
                          (/dev/rmt1) for QRYINQUIRY operation"

This is a new one on me.....so the write failed, and TSM marked it R/O.

I let audit library run again for about 45 minutes, and it just sat
there, doing nothing....

I tried with checklabel=no and got the same "Volume in use error".

AIX diag reports no problems, but there is some TAPE_ERR4 messages in the
error log when the write failed.  I'm checking these out now...but other
than this one volume, TSM seems to be running fine.

Thanks a lot for the tips!  If ya'll can think of anything else i might
try i'd really appreciate it...

later!
