Hi Bill, I can confirm that the 74.7 record will indeed report data in mixed environments. Activity as well as buffer overruns and errors for all ports on the director are reported. Similarly, if your Disk Subsystem supports the records, the 74.5 and 74.8 RAID Rank and Link statistics can report on both CKD and FC/FB (Open) data.
These are highly accurate records with minimal overhead.
