Mauro,

Thank you for your reply.  I am still having problems executing the command
you suggested:

adsm> q vol access=unavailable

Volume Name               Storage      Device      Estimated    Pct   Volume
                          Pool Name    Class Name   Capacity   Util   Status
                                                        (MB)

                           OL

adsm> update volume dbi458 access=destroyed wherestg=dr_tape_pool

      dltclass
ANR2116E UPDATE VOLUME: Access mode for volume DBI458 cannot be changed to
"destroyed" - volume does not belong to a primary storage pool.
ANR2212I UPDATE VOLUME: No volumes updated.

I am sure I am missing something here.  Any clues ?

Thanks
