     Actually if you simply do a "query content vol_ser" you will only =
see
     the active files left on the tape...

Hi,

we lost three 3590 tapes due to "ANR8359E Media fault detected ...". Th=
e
tapes always belonged to storage pools, which we do not back up. So all=
 I
did was to delete the volumes (DISCARDDATA=3DYES), informed the affecte=
d
users and urged them to do an incremental.

These things happened when we were on V.2. I did not see any possibilit=
y
to determine, whether the affected backups were active or not. So I
decided to not worry about it. (What else could I do, if I were able to=

identify the inactive copies?)

An interesting question is, whether the SQL interface of V.3 allows us
to identify inactive copies on a storage pool volume. A quick look at
the SQL table layout does not give me any clue :-(
Maybe the DEACTIVATE_DATE in the BACKUPS table gives the wanted
information, but how do I get the connection from an entry in the
CONTENTS table to the corresponding entry in the BACKUPS table? Any ide=
as?
