I had a client that was trying to connect a CX700 to their AIX TSM system. What they say is that the SANDISCOVER was causing problems and IBM suggested they disable it in the DSMSERV.OPT. Been working ever since. I wasn't involved in the issue, this is just what they told me they found out. But you might want to give it a try.

We use EMC storage (DMX and Clariion) for all our TSM disk based storage (db, log, disk storage pools, file device pools). It just works - really well. Is your storage online and available before you start TSM? Are you using filesystems or logical volumes? Are you using PowerPath, or some other mpio driver? What OS are you using for for your TSM server (we use AIX)?

Environment: TSM sever using purely for IBM Commonstore for SAP archiving. TSM database & log files on EMC Clarion Storage - mirrored across LUN' on EMC. 2TB of disk pools spread across 4 X 500GB LUN's on EMC storage. My question: Is there a way a can tell TSM not to "VARY-ON" my disk pool volumes during startup so that I can vary-on them manually once TSM is up? I think that TSM is trying so hard to vary-on these volumes that the EMC path timeout. Has anyone experienced something similar?
