It's been many a year since we moved to duplexing, by which I mean 'system managed duplexing'. Assuming that you are at an appropriate hardware and CF code level, you don't define duplex capability. It's just there. . There is no 'hardware definition' for duplexing. Duplexing is defined in the CFRM policy for structures that are to be duplexed. If the active policy specifies duplexing for any structure, then that structure is duplexed to the CF named in the policy. Once enabled in a policy, duplexing can be turned off or on via the OS command SETXCF
So to answer OP's question, How can I tell?, look at the policy definition(s). Also D XCF,STR for any or all structures. . .
