I have a recent set up, TSM 6.3.4.300 on AIX 7.1, LTO5s and I too
always thought that the atape driver did load balancing. However I
for each tape drive?

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
Hello Wanda,
As TSM allocates drives in order, you have to distribute drive between the HBAs
in a round robin way (with 4 hba : drive 1 on hba 1, drive 2 on hba... drive 5
on hba 1 and so on). I prefer doing this at VTL level using mapping policy (i.e
access groups on Data Domain).
