Assign disks to ControllerB , 270c

Gents,

  We have a NetApp 270c with 14 143GB disks, all visible to ControllerA.

  I would like to setup ControllerB's root volume, and proceed with my tasks.

  I have unassigned 7 disks from ControllerA, and can verify some disks are not owned by ControllerA.
  When booting ControllerB, and going into special boot mode, I am not able to go any further, as it does not see these disks.

  When going into maintenance mode on ControllerB, I am not able to see the disks either. 

What am I missing?

Thanks!

On controller B maintenance mode, do you see the 7 disks when you type "disk show -n" ?  If you see them then run "disk assign all".. if not more troubleshooting... do you see any other disks with "disk show -v" ?

Check the cabling. The disk shelves (unless really old) should be auto-terminating.

Are both controllers connected to the external disk shelves in the same way? Remember controller A is the opposite way round as it's upside down. Both controllers need connecting to the disk shelves, one to each shelf module (controller A to module A, controller B to module B). You can do HA cabling also if you have enough cables by returning the loop to the opposite controller.
