HP High Availability FC Disk Array 30/FC User Guide - Page 135

Failing component Continue after failure? What happens and how to recover Disk module Yes Provides the same features as the basic configuration but with better performance and higher availability. With RAID of any level supported by MPE/iX, applications continue running. System Administrator or service provider replaces module. SP Yes If one SP fails, the System Administrator can access the LUNs owned by the failed SP by accessing the remaining operational SP with the other host. If a host adapter fails, the System Administrator can access the LUNs in the array with the other host adapter. The System Administrator must change the path and SP ownership of the LUNs for the failed SP or failed host adapter by using SYSGEN and ioconfig, respectively. There is no automatic transfer of LUN ownership or path for this configuration type. Fan failure Yes within fan pack Power supply Yes SCSI-2 adapter/ No* cable 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 and System Administrator restarts the operating system, if necessary. I/O operations fail to all physical disk units configured on SP attached to a failed SCSI-2 adapter/cable. System Administrator can transfer control to the other SP by changing host(s) and array configurations. 5-12
