Hi Rick,
1. EMC storage is Clariion CX700 and is online and available.
2. Using file systems which is mounted and available when starting up
the server.
3. I'm using Powerpath with one HBA seeing both SP's on EMC.
4. OS is AIX 5.3.
This is the current output of powermt display dev=all:

I think we need some more info.
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)?

Hello,
I have an interesting issue where when trying to startup TSM, the EMC
storage path's change status to dead.
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?
