In order to have multi session "simultaneous" restore from tape pool
then you must have this data in a pool that has collocation by filespace.
If you have a big enough disk pool such that if you did a restore
before migration had moved the data, then a multi session restore
would use the disk pool and be multi session.

Hello all,
        I am trying to work in a multi session backup and be able to use a
multi session restore.  What I have found is that with the
maxresourceutilization set to 8 that my 350GB 8 processor AIX client is
using only 4 data sessions and 4 control sessions.   The data all goes to
the disk pool and then the migration will use only 1 tape drive for this
data.  I then assume a multi session restore is not going to work.

1)      how can I get this backup to use more sessions for data transfer?
2)      Am I correct in believing that the multi-session restore is out
because of the actions of the migration process?  MUST this go direct to
tape to have multi session backup and RESTORE?

Thanks in advance,
Matt
