From: William Rosette [mailto:[EMAIL PROTECTED]] > Does any TSM gurus have any suggestions for our AIX admin [donning my advocacy armor] I still don't see any reason to create redundancy for the disk storage pool. Unless you're not using a tape library, there's no reason for it. The disk pool should get flushed to a more stable medium, and that flush should take place fairly soon after the client backups to disk finish. Why waste gobs of disk on something that's going to flushed clear every day? As far the db and log are concerned, just create volume copies with TSM and make sure the copies are on disks that are on separate disks. That's really all there is to it. -- Mark Stapleton ([EMAIL PROTECTED])
