Thanks for pointing that out, Ray. The point I was trying to make was that there is no SCSI/FCP performance data that is put into the CP monitor data stream, where the usual z/VM performance tools can get at it.

There is certainly is architected performance data for SCSI. Check out log select, log sense, 7.2.14 Statistics and Performance log pages, 7.2.15 Cache Memory Statistics log page, etc in SPC-4. sg_logs should retrieve this data, but I'm not sure if the all of the scsi tools work on linux on z.
