We maintain 3 processors and a CF across 2 datacenters in the same IODF. If you want to be able to see a complete view of all of your devices and connections across all of your raised floor it’s the only way to do so I believe. It also allows us to maintain our DR configuration in sync with everything else.
Jerry Whitteridge Manager Mainframe Systems & HP Non-Stop Albertsons Companies -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Michael Babcock Sent: Friday, July 10, 2020 11:20 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: EXTERNAL EMAIL: Two Processors and One IODF 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? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ________________________________ Warning: All e-mail sent to this address will be received by the corporate e-mail system, and is subject to archival and review by someone other than the recipient.
