imagine 2 Controller in HA-mode, each Controller has an SAS adapter card with two ports and a connection to both IOM12s of a disk shelf. The disks of the shelf are owned by controller 1. If SAS adapter card in controller 1 fails, controller 1 can not see the shelf and disks anymore. Do the SVMs failover to controller 2?
I know its best practice to use 2 adapter cards per controller to remove the adapter card single-point-of-failure, but I want to know what would happen?
