We have 2 different tape drives for Onsite (Backup type pool) and
Offsite (Copypool type pool) Storage pools so we have to do manual
reclamation of our Onsite pool every week. To accomplish this I created
a TMPPOOL (Backup type pool) pointed at the drive used for the Offsite
Pool. I then use move data  to move volumes from the Onsite pool to the
TMPPOOL. This causes the Onsite Pool tapes to be scratched. Then I move
the TMPPOOL volumes back to the Onsite pool.

        Subject:        MOVE DATA Questions

        Hello all,

                I have some questions regarding MOVE DATA commands.

        Imagine I have 3 tape volumes.

        B       60% full.
        C       10% full.
        D       0%  full. (Any scratch)



        Is it possible to movedata from B to D then C to D and end up
with B & C at 0% and D at 70% thereby emulating space reclamation?


        OR


        Does ADSM always ask for a new scratch tape when a move data is
performed so I will end up with

        (Assuming movedata for b is done THEN movedata for C)

        B       0%  full
        C       0%  full
        D       60% full
        E       10% full



        Basically, Is it possible to do any kind of space reclaim using
on or offsite move data cammonds?



        I dont think so, but a colleague of mine does. If the argument
settles in my favour I'll buy you a virtual pint!
