After upgrading, did you delete the drives from ADSM and redefine them?
If not, those drives and the volumes written on them are still B-type from
the ADSM server point of view. Those volumes are refused to be mounted
on 3590E drives (and vice versa), as long as their access is READWRITE.
When I was in that situation, having a mixture of 3590B and 3590E drives
(from the ADSM server point of view, not in reality), I did the
following:
- redefined the drives,
- set access of affected volumes to READONLY,
- MOVE DATA,
- set access to READWRITE again.
I did not have to relabel the volumes.
