-- snip -- Not having any problems with base and aliases definitions in CSS0 but I'm trying to put the aliases in CSS1 (z9 BC). Haven't used CSS1 before. When I defined CSS1 in HCD, it seems to want unique LPARs and ChpIds in CSS1, which is not ideal. I did an experiment with a controller/devices in HCD and HCD let me specify CSS1 for a home for the experimental 'aliases' that I defined but it wouldn't let me make a PROD IODF, msgCBDG199I. -- snip --
Jack, I'm not sure what you're trying to do, so I'll just give a little background info. The z9 BC supports 2 Channel Subsystems (CSS0 and CSS1). The EC supports 4. A logical LPAR is associated with one CSS. A Channel Subsystem may have 2 Subchannel Sets (Multiple Subchannels). Currently, Subchannel Set 1 is restricted to only Alias addresses. So, if you are trying to define a new CSS, then you do indeed need a unique LPAR (but you can span Chpids). But, if you are tryining to move your DASD alias addresses from SS0 to SS1, you don't need to define another CSS.
