Wanda, We start backups in earnest at 10pm. At that time, all of our 206 virtual drives are busy. So we don't worry about balancing across HBAs. They all have I/O on them.

TSM 7.1.1 on AIX So I have a customer putting in a VTL, which will have 96 virtual drives. Those virtual drives will be spread across 4 HBA's. What sort of strategies to people use to keep TSM from starting a BACKUP stgpool process and picking 4 virtual drives all on the same HBA? Is it dependent on the order you do your DEFINE DRIVE commands? Better to set up multiple virtual libraries? Any suggestions appreciated.
