Ahh, OK.
Q VOL does NOT show tapes that are used for DB Backups (or Backup Sets) -
so DONT rely on Q VOL telling you every volume that TSM is using.
Q VOL will tell you what tapes are being used by TSM to store Backups and
Archives (by the BA client and the API client). It will also tell you what
You should backup your storage pool with directory information (its a
primary pool), to a secondary storage pool and send that offsite for your
disaster recovery! (But its not absolutely required for DR - you can
restore your files without the DIRMC information).
If the primary ever gets destroyed
The ITSM Administrators Guide is explicit that you should not use AIX
mirroring on Raw Logical Volumes which are used for Log or Database.
Something gets overlaid and it won't work.
However, this still leaves open the question if it is OK to use AIX
mirroring on Raw Logical volumes which are used
As I understand it, the gripper is most often used when there is a request load a tape
into a drive which already has a tape in it (or maybe an unload pending).
The sequence is load new tape into gripper 1, move to drive, remove tape into gripper
2, load drive from gripper 1, put away gripper 2.
I have been doing rawlv AIX mirroring for disk storage pools since ADSM was
delivered for AIX. I have *never* had a problem, and when properly laid out,
get outstanding performance as well.

If the data "was only on the disk", I would say your disaster recovery
preparation needs serious fix!
The idea is that you backup the whole storage pool *hierarchy* to a copy
pool. For example hierarchy DISKPOOL -> TAPEPOOL must be backed up with
1. ba stg diskpool copypool
2. ba stg tapepool copyp
When you say no tape backup produced, I am going to infer that you mean no
tapes are being produced for offsite storage. If this isn't happening, you
MAY have run out of scratch tapes. The following select will display
storage pools that are close to their limit of tapes:
select stgpools.stgpool
