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.
