RE: P7 to P9 test migration/recovery using BRMS - noticing significant tape seeking, unloading, loading during the recovery

Jim,

1) This was a "temp solution".
I only selected the restore items from the same volume which were in sequence.
Restore streamed with no rewind, etc.
I repeated this process for each volume listed in the recovery.

2) Fiber Switch is zoned that all LPARs see all drives, no movement of SAS adapter.
We updated the zoning to include the new P9 SAS adapters.
So all P7 LPARS and P9 LPARS are seeing all four drives in the library.

Paul

Paul:

You indicated you solved the issue you were raising? How exactly did you do
that?

Are those drives Fibre connected or SAS? Since we know you do not use VIOS,
are these drives zoned into all the partitions (assuming Fibre) or do you
move the SAS adapter between partitions?

If you do a WRKMLBSTS on the P9 does the library show up with multiple
drives or just a single drive?
