I have a Storgedge 6130 Array connected to a Fiber Switch then to the Array from a Sunfire V890. In Common Array Manager All Volumes are hosted on the A adapter and when i select it to change it to the B Adapter it Fails. Any ideas why this may be happening?. If possible I would like to have certain Volumes on the Separate Controller  for redundancy,or is it only possible to use the A Adapter, What are the requirments needed to have both controllers hosting different volumes

Hi
Very strange, as long as your fiber switch, OS mpixo is enabled and volume mapping is correctly, It should auto switch between A and B controller if one of the controller failed.

try verify both path is online by using
e.g:
# luxadm display /dev/rdsk/c6t60060E80144283000001428300000219d0s2

result should be look like; both must be online.

  /dev/rdsk/c6t60060E80144283000001428300000219d0s2
  /devices/scsi_vhci/ssd@g60060e80144283000001428300000219:c,raw
   Controller           /devices/pci@1d,700000/SUNW,qlc@1/fp@0,0
    Device Address              50060e8014428304,21
    Host controller port WWN    210000e08b89a5fc
    Class                       primary
    State                       ONLINE
   Controller   /devices/pci@1e,600000/SUNW,qlc@3/fp@0,0
      /pci@1e,600000/SUNW,qlc@3/fp@0,0/disk

Seem like no problem with the configuration.
Are you using 2 x 2 port FC card or 2 x 1 ports FC card?
have you test with power off the A controller to test B controller whether can online automatically?

I got system with similiar to your configuration also but it work fine. one online and other is standby.
When I power off active controller it will go to standby controller automatically.
