Any and all replys are appreciated.
The good news is that z/VM is far better at this sort of thing than z/OS and you don't need to re-IPL. Since They are not requiring a POR, they must be using HCD to also dynamically change the CEC I/O configuration. When HCD changes the active I/O configuration of the z/VM LPAR, CP will be told about any added or deleted devices. Added devices will the varied online automatically. When you re-IPL z/VM, those devices will be there and CP will sense them at IPL. When you POR the box, the updated IOCDS is activated and those device are still there. All you have to do is ATTACH the devices (if you want) wherever you need them and update SYSTEM CONFIG and/or USER DIRECT to account for them on the next IPL. Bottom line: A miracle occurs in Step 2.
