I have HA-pair of FAS3140 controllers connected to 3 stacks. Four DS14-MK4-FC shelves (stack 1), three DS14-MK2-AT shelves (stack 2) and one DS4246 shelf (stack 3). I'm trying to gather controller to shelves cabling information and I'm stuck with a couple of questions:
1. "storage show shelf " shows only stack 1 and stack 3. "environ shelf" shows all 3 stacks. Why is stack 2 missing from "storage show shelf" output?
2. In multipathing configurations both controllers have access to a stack from two loops. But it's unclear if controller is connected to the first shelf IN port or the last shelf OUT port. I can extract FC port to IOM (A or B) cabling info from the "storage show shelf" output. But how do I now which module port (IN or OUT) FC port is connected to? Config Advisor isn't helpful here, because it doesn't show even the FC port to IOM mapping.
IOM is SAS and it is possible to reliably track.

Does it show IN/OUT IOM ports mapping?
