HP Surestore Disk Array 12h and FC60 - Manual (Page 114)

114 Topologies for HP-UX
Fibre
Channel I/O
adapter No on path to
failed adapter;
Yes if array has
dual controller
modules and
alternate paths
have been
configured 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.
Fibre
Channel
cable No on path to
failed cable;
Yes if array has
dual controller
modules and
alternate paths
have been
configured 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.
