Failing component Continue after failure? What happens and how to recover Disk module Yes SP Yes Provides the same features as the basic configuration but with better performance and higher availability. Applications continue running. System Administrator or service provider replaces module. With HP-UX 10.x, if one SP fails, ownership of the failed SP's LUNs can transfer automatically to the remaining operational SP. If a primary and an alternate path have been configured in LVM, LVM can switch automatically to the alternate path (LVM applies to HP-UX 10.x and later). These operations are transparent to the user. Fan failure Yes within fan pack Power supply Yes Applications continue running. System Administrator or service provider replaces module. If a redundant power supply module is present, applications continue running; otherwise, the disk array fails. Service provider replaces power supply and System Administrator restarts the operating system, if necessary. SCSI-2 adapter/ No* cable If the adapter/cable fails, I/O operations to array disk units fail. Authorized service provider replaces adapter or cable and System Administrator restarts operating system and applications. Configuration, HP 9000 Series 700 3-9
