What happens and how to recover
I/O operations fail along the path through the failed cable. If the
host has two Fibre Channel adapters connected to a dual-
controller module disk array, the array can be accessed through
the operational path if primary and alternate paths have been
configured in LVM. If so, LVM switches automatically and
transparently to the alternate path. The authorized service
provider hot-swaps the failed cable.
