If you wanted to setup (from scratch) a DASD performance monitor (for RAID)
and you weren't allowed anything but RMF and MXGSAS, what SMF records would
you keep and why?
-- snip --
MVS System Management Facilities (SA22-7630) is a good place to start.
I would choose not only the RAID relevant records, but also Channel, Ficon
Link, .. records in order to see the whole picture.
Here is my short list.
SMF 73 Channel path activity
SMF 74 - 5 Cache Subsystem
- 7 Ficon director
- 8 ESS link status
SMF 78 - 3 I/O queuing activity
SMF 79 - Monitor II records (in case you want this kind of a snap shot).
