Table 9 Single-System Distance Topology Error Recovery (cont'd) Failing Continue component after failure What happens and how to recover 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 dualcontroller 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 dualcontroller 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. 114 Topologies for HP-UX
