Failing component Disk module Continue after failure? What happens and how to recover Yes (9.04) Yes (10.x) Applications continue running. System Administrator or service provider replaces module. Provides the same features as the basic configuration, but with better performance and higher availability. Applications can continue to run after the failure of a single disk module. SP *No (9.04) HP-UX 9.04 Yes (10.x) If one SP fails, the System Administrator must reassign ownership of the failed SP's LUNs to the operational SP by using Grid Manager. Also, the path to the operational SP must be used and can be changed by using LVM. Once these changes have been made, access to all LUNs on the array is possible. Fan pack Power supply Yes (9.04) Yes (10.x) Yes (9.04) Yes (10.x) SCSI-2 adapter/ *No (9.04) cable *No (10.x) 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 switches automatically to the alternate path. These operations are transparent to the user. Applications continue running. System Administrator or service provider replaces module. If a redundant power supply module is present, applications continue running; otherwise, disk array fails. Service provider replaces power supply. The System Administrator restarts the operating system if necessary. If the SCSI-2 adapter fails, no I/O operations are possible between the host and the array. Authorized service provider replaces adapter or cable and System Administrator restarts operating system and applications. If the SCSI-2 adapter fails, no I/O operations are possible between the host and the array. 4-8
