Dave, The crypto-stuff is lots of fun.
I am going to ask you some questions... the answers will help you "lay-out" your system. 1. Are you going to have any crypto co-processors online to TEST? 2. Are you going to share any crypto co-processors between TEST and PROD? 3. Is the lpar CF1 a coupling facility? Co-processors, useage domains and control domains are very different things. In your case you have 4 co-processors (aka 2 CEC2C features). Each co-processor has domains 0 - 15. An lpar can have "control" over multiple domains (i.e. administration.. this becomes very important with Trusted Key Entry Workstations). A domain on a co-processor cannot be shared with multiple lpars. You might ... - take 1 co-processor and assign (aka ONLINE) it to TEST. Useage Domain 0, control domain 0. - take 3 co-processors and assign (aka ONLINE) them to PROD. Useage Domain 1, control domain 1,0. (I am assuming that CF1 is a coupling facility and will not need a co-processor) -Rob Schramm This e-mail transmission contains information that is confidential and may be privileged.
