We are a monoplex z/OS system and will be moving to a new data center late this
year. When we move, we will get a new CPU (z9 now) and replace our Shark
(2105-800) with something else. Ideally, the desire is to keep our existing
system running while testing the new system and do a quick cutover using
non-disruptive move software to move DASD volumes from old unit to new.
Now we're thinking, how are we going to move that data? They think we would be
down too long to dump and restore (3592). Likewise on physically moving the
Shark plus it could be risky. So I ask you big, bad, concurrent copying,
GDPSers out there...
What are our options for quickly moving about 400 3390-3 and a few 3390-9, or
replicating our current volumes to a new unit located a few miles away?
I would appreciate any advice or pointers to things I should check out. We will
probably have some help from our Business Partner but we need to start thinking
things out now.
The cheapest and potentially the most secure method:
1. Connect both DASD boxes to the host.
2. Use SMS + DSS (or FDR) - DISNEW existing volumes and COPY existing
datasets.
3. For DB2 use REORG with DISNEW.
4. For system, pages, etc. plan an 1/2-3/4 hour outage.
5. It does not impact I/O (can be done so).
Advantages:
1. It requires no add-on tool. Means it's free.
2. It allows both dasd boxes to be all the time replicated (mirrored).
3. It can be tested and measured as long as you need, no constraints on
time, no service windows for testing.
Disadvantage:
1. It does not manage few system disks, so it require short service window.
