I have found out that you hear different things from different TSM people about the same situation. But I know from experience that you must place your DB volumes on seperate filesystems on seperate physical volumes if possible for performance. Also, your 1GB volumes won't be to bad because they will fill up quick and once full, they won't get hit anymore. If you want to consolidate, then start reducing the database and releasing space. That the released space and make larger filesystems for a new Database volume. Do that until you are satisified.

We have been working with IBM ATS support about poor performance issues with our TSM config, and they say that our problem is because we have all 37 volumes in one AIX logical volume/filesystem. They have had us create 32 new AIX logical volumes/filesystems (don't need 37 because our db is not very full after running CLEANUP BACKUPGROUPS), each with a 1GB TSM DBvol inside, all of which are on separate ESS loops. They said the smaller DB volumes are better! Argghh!! -----Original Message----- From: Robert L.

Create the new DB's and extend the DB and then delete the old DB's. The data will migrate over to the new extended space. Any reason you had 37 1GB volumes for your DB's. IBM told me not to really go over 10 volumes on your DB and to be sure they aren't on the same drive if you can help it. I would suggest that if you could, create 5 8GB new volumes for a total of 40GB and move the DB over to the new 8GB partitions.

If I define the new dbvolumes on the new disks, do I then just extend the db, and then do a del dbvol on the old ones? Does the delete make the data migrate over? Do I have to do a reduce db for any reason before I do the delete dbvol? Can I do the delete with the server up and running?
