Re: upgrade path from 3590E to 3592

        The 3590 and 3592 tapes can coexist in the same frames and
slots. They can all be intermixed.

        The 3590 and 3592 DRIVES cannot coexist in the same frame, so
you must upgrade one whole frame at a time. On our 4 libraries, we
always upgraded the L22 first, as we could then put 4 3592 drives into
the place where the 2 3590 drives were before (so we gain 2 extra drives
to move the data to the new media), but I don't believe that it has to
be done first.

I posted the following message a couple of months ago and a lot of you
helped me out.  Looks like we will have the funding for converting one
D12 to D22 with two 3592 drives this fiscal year.  However, management
wants to purchase only 100 3592 tapes this year.  My question is:

Can 3590 and 3592 tapes coexist in the same D22?  A D22 has 335 slots.
I want to fill it with 100 3592 tapes and 235 3590 tapes.  Is this
config supported?  The 3494 is very full.  I can use every single slot.

Also, can we convert the L12 before the D12?  The two 3590 drives in the
L12 are the oldest and the most problematic.  I want to get rid of them
first.

Thanks,
Eliza
