Check to see that Collocation is not enabled for that STg pool, if
collocation is set for 'yes' then during migration when the data from
another client is set to migrate to your stgpool it will need to mount
another tape to keep that data together .

Subject: stgpool migration starts 2nd scratch tape?



Hmm.  Why would ADSM start a 2nd tape (during a normal stgpool
migration) when the (first) tape it's been writing to is still
present and enabled?  In the following log, we first write to D0012 a
couple of times, then dismount it, and then _remount_ it (in the other
drive), but also mount a new scratch volume (D0013) and decide to write to
that.

Is there some parameter I should be setting?  I'd expected everything to
write on one tape (only 17GB of data, and we've got 35GB DLT tapes).  D0012
is now 41% full, still R/W access, and in the "filling" state.

Thanks.
