We are in the process of bringing DR back in-house and have a new
z15-T02 in our new facility (our current "home" machine is a z14-ZR1).
I want to be able to manage both processors from a single IODF. I'd
like to have the same CHPIDs, CUs, and Device addresses both at home and
in our DR machine. I have the new processor defined in our current
IODF and have used the CHPID mapping tool to map the PCHIDs to CHPIDs.
I have tested adding devices with the same address to both processors
and that seems to work (as long as I define the CUs to both processors
first. I tested adding a range of 16 tape drives).
My questions are this:
1. Is this something we even want to do (same IODF, same device addresses)?
2. What's the best way to move the IODF at home to the DR machine?
3. Are there any gotchas we need to watch out for?
4. We have IBM DS8886s and are using Metro Global Mirror Multi-Target
w/Practice. Any concerns here?
5. Am I crazy for even entertaining this idea?
6. Any alternatives I need to consider?
