What kind of drive are they emulating? Are they emulating IBM drives with Atape driver? My understanding (I've been trusting this for years) will auto load balance across hba's.

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).
