If it's 1 filespace, then just one restore session no matter how
much data. Well, let me modify that. If you have filespace say
/test and then have say ten folders under it such that you have
/test/dir1, /test/dir2, etc. then you can do multiple restore sessions
with each specifying a separate one of these, I believe. Haven't tried
it but should work. However there will most likely be times where
several sessions are waiting on same tape.

Hello,
I'm not sure i understand that feature, therefore the following question:
1 Filespace with 100 GByte active data spread over 10 tapes and 10
tapedrives available.
Can you restore this filespace from all 10 tapes at the same time or should
the tapes belong to different filespaces?
Kind Regards
Stefan Holzwarth

Betreff: Re: Multi session backup restore question
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
