Ok, I've looked over some more info and some comments that I've got.

        We are running  (1) 3494 library with (2) 3590-B1A drives attached
to an IBM Netfinity 7000 M10 server running WinNT4 SP5, TSM version 3.7.3.
        I'm thinking of having the CE convert both drives to the E1A version
on the same day. When he gets done then I would do the following:

        1. UPDATE DEVCLASS 3590CLASS FORMAT=DRIVE
        2. DELETE DRIVE IBM3494A MT0.0.0.2
<-----FOR THE FIRST DRIVE
        3. DELETE DRIVE IBM3494A MT0.0.0.3
<-----FOR THE SECOND DRIVE
        4. DEFINE DRIVE IBM3494A MT0.0.0.2 DEVICE=MT0.0.0.2    <-----FIRST
DRIVE
        5. DEFINE DRIVE IBM3494A MT0.0.0.3 DEVICE=MT0.0.0.3    <-----SECOND
DRIVE
        6. Run a SQL script to get a list of tapes in the library that would
need to be made readonly: select volume_name from volumes where
stgpool_name='TAPEPOOL'
        7. Do an UPDATE VOLUME XXXXX ACCESS=READONLY for each tape on the
list.

        If I understand this process correctly, as the tape reclamations are
done on the tapepool tapes they will move from a readonly status to a
readwrite status and then become usable with the greater capacity. Also, as
the copypool tapes come back from offsite they will also then be usable with
the greater capacity.

        Am I at least close on my thinking??
