Topology and Array Planning Table 11 High Availability, Distance, and Capacity Topology Error Recovery Failing Continue component after failure What happens and how to recover Disk module Yes Applications continue to run on all supported RAID levels (RAID1, 0/1, and 5). The system administrator or service provider hotswaps the failed disk module. Controller modules No on path to Ownership of the failed controller module's LUNs can transfer failed controller automatically to the remaining operational controller module if module; primary and alternate paths have been configured in LVM. If so, Yes on alternate LVM switches automatically and transparently to the alternate path through path. The system administrator or service provider hot-swaps the second failed controller module. controller module Fan module Yes Applications continue to run. The system administrator or service provider hot-swaps the fan module. Power supply Yes modules Applications continue to run when one power supply module fails. The system administrator or service provider hot-swaps the failed power supply module. HP Fibre Channel-AL Hub No on path to I/O operations fail along the path to the failed HP Fibre Channel- failed hub; AL Hub. I/O operations can transfer automatically to the other Yes on alternate pair of cascaded path to other HP Fibre Channel-AL Hubs if primary and alternate paths have pair of hubs been configured in LVM. If so, LVM switches automatically and transparently to the alternate path. The authorized service provider hot-swaps the failed HP Fibre Channel-AL Hub. 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. Topologies for HP-UX 123
