Re: cannot dismount tape

 
Check the actlog- there looks to be no scratch tapes! Or a problem mounting 
volumes in the library.

Thanks Richard.

                               conds).           


There´re no sessions requesting that tape and if I excecute query request:

ANR8346I QUERY REQUEST: No requests are outstanding.


I´ve 2 drives, and that situation had happens with 2 drives and many tapes 
since many days ago. When I restart the sever the problem disappeared for a few 
days and happens again.

There´s another test that I can make?

Thanks again

Marcelo.

Marcelo -

Use Query PRocess and Query SEssion Format=Detailed to see if the tape/drive is 
actually in use, and Query Request to see if an associated tape is needed.

A situation which goes on for days, as you have encountered, is abnormal, and 
may indicate that a tape mount is actually not completing, and that can be due 
to a drive defect or even a tape already in the drive (stuck there, after a 
previous dismount failed).
Inspect the drive for problems. Depending upon your drive type, a Reset or 
power cycle may clear its condition. But thereafter keep an eye on the drive 
for further problems, where a technician would have to work on it.
