What happens and how to recover
I/O operations fail along the path through the failed adapter. If the
host has two Fibre Channel adapters connected to a dual-
controller module disk array, the array can be accessed through
the path to the operational adapter and controller module 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 replaces the failed adapter
and the system administrator restarts the operating system and
applications.
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.
