It seems its taking longer for our drives to mount/dismount tapes.
We just migrated our (5 instance in one LPAR TSM env) on AIX 5.3.TL9 from a p590 to a p560. We kept the same OS. We are attached via fiber channel to a 3494 (yes we zoned correctly one zone for tape drives and one for disk-DS8000). I don't remember what the rule of thumb is for the HBA/TAPEDRIVE RATIO. The AIX sysadmin said we each tape drive was dual pathed from the 3494 to the switch and p560. Any ideas on how to troubleshoot as this sounds like a SAN/HBA/ZONE problem rather than a TSM problem? Thank you, Bob Molerio
