MSA 2212fc: Wrong cabeling?



I'm new to fibre channel and have a small problem. My SAN is a MSA 2212fc. This is my cabling:


Controller A Port 0 -> SW-FC-1 -> Three ESX-Servers, each Port 0 (vmhba2)

Controller B Port 0 -> SW-FC-2 -> Three ESX-Servers, each Port 1 (vmhba3)


The ESX-Servers see the LUN only on vmhba2. On vmhba3 they see only an "enclosure". If I disconnect controller A the LUN get lost. I think controller B should provide access to the LUN?


Is this a configuration problem or is it necessary to add a seconds connection for each controller:


Controller A Port 1 -> SW-FC-2

Controller B Port 1 -> SW-FC-1

Usually you connect each controller to both SANs.

But you should also check the presentation settings, if each LUN os presented to each port.

Hope this helps!

The LUN is presented to all ports.

Currently I've only enough cable to connect one port of each controller and I thought it should be enough to connect one port of each controller.

The required cables are orderd ;)
