If you do have z/VM then, as I said, you can make Dynamic I/O changes either via HCD or Dynamic I/O commands and that includes adding LPARs. For Dynamic I/O commands, adding an LPAR is done by: CP DEFINE LPAR USER04 MIF 4 and you have a new LPAR. In fact, I did this for a customer a few months ago. You then add the new LPAR to the access and candidate lists for the existing channels, e.g. CP MODIFY CHPID A0 ADD INIT USER04 ACC USER04 give the LPAR access to the devices themselves, e.g. for most device types: CP MODIFY IODEVICE A100-A01F UNITADD 0 CU A000 ADD PART USER04 and so on. OSAs are a slight pain and a MODIFY IODEVICE doesn't make them available to new LPARs so (after doing a switchover to a backup OSA), you have to take the channel/devices offline from current LPARs then delete and redefine them: CP DELETE IODEVICE E000-E03F UNITADD 0 CU E000 CP DEFINE IODEVICE E000-E03F UNITADD 0 CU E000 PART X Y Z USER04 then bring them back again. It's a bit fiddly but all works fine. It needs care but then making I/O changes to a running CEC is something to be careful about anyway. If you use z/VM HCD then it does all that fiddly stuff for you (and doesn't have that restriction about dynamic OSA changes, as far as I know) but HCD does require that you use the Windows HCM application to manage your IODF.
