- One point is that you gain virtually nothing by 6 volume groups. You can put the six LUNs in a single VG, no performance difference I believe.
- Have you tuned the queue_depth of the LUNs based on AMS documentation. Check it by "lsattr -El hdiskX" Here is my question from the group: Which one performs better? a- One big TSM volume on a 2TB LUN b- More than one TSM volumes on a 2TB LUN Thanks
