One way to get multi-restore to work is to collocate on filesystems in the tape pool. If one collocates to the node then the problem that your discussed happens. This is a designation of the pool so all nodes going to this tape pool will be collocated by filesspace and that can eat a lot of tapes. Another way is to logically break up your server into say four nodes. Each node has a domain/excludes/includes that limits it to certain set of filesystems. As long as the pool that they are going to is collocated by node, they can go to the same tape pool. Now during restores there is no contention for the same tape.

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?
