Thanks for confirming my own research on the subject. Regards,

Mary Anne Differences b/w running native LPAR and running as a z/VM guest In a single system: The only issue I’m aware of is some strangeness with your performance monitors. In a SYSPLEX: --A new CFRM policy is required, specifying SIMDEV for the coupling facility: CF NAME(CFCC1 TYPE(SIMDEV) MFG(IBM) PLANT(EN) SEQUENCE(0000000CFCC1) PARTITION(0) CPCID(00) DUMPSPACE(2000) Type Number (TYPE) - SIMDEV specifies that this is a z/VM simulated message device type. Manufacturer (MFG) - IBM® indicates IBM as the manufacturer. Plant (PLANT) - EN indicates Endicott as the manufacturing plant. Sequence # (SEQUENCE) - The 12-byte field will contain the CF Service Machine user ID right justified. Pad all leading unused characters with EBCDIC zeros. For example, if a CF Service Machine of CFCC1 is specified, SEQUENCE is 0000000CFCC1. Your DR provider may have a different CF name. --A different CLOCKxx member may be needed specifying SIMETRID: TIMEZONE W.04.00.00 ETRMODE YES ETRDELTA 10 ETRZONE YES SIMETRID 00 --Possible CFSizing needed: If you are on a processor that has a lower level of CF Code, you may need to resize your structures. For example, if your DR provider has a z10 (CFLEVEL 16) and you are running on a z9 (CFLEVEL 15), you may need to increase the storage size of the CF. >It's been many, many years since we've run our sysplex under zVM.
