It does not apply to a disk array with two SPs. This disk module has reported a media defect that could not be cleared by the SP. The SP encountered multiple errors while attempting to load the cache image from disk. This message can indicate multiple drive failures. The SP found inconsistencies in the cache image on the disk. This can indicate a failure or abort of the cache dump. The SP successfully read the control portion of the cache image on disk, but found the data portion to be incomplete. This means that a failure or abort occurred during the cache dump. Probably any LUNs with write-cached pages are inaccessible and must be rebound. To identify such a LUN, read message 0x90A in this table. The SP found the vault disks containing the cache image to be in a different order than when the cache image was dumped to disk. This means the disks were swapped at power down. The disk modules must be restored to their original order before the SP can load the cache image. This SP, which is operating in nonmirrored caching mode, has too low a PROM revision level. Write caching cannot be enabled. A RAID-3 LUN cannot be enabled because SP memory allocated for RAID-3 processing is not available. This can happen if the disk array is powered up after SP memory has been removed, or when ownership of the LUN is transferred to a peer SP that does not have enough memory. No RAID-3 LUNs can be enabled because SP memory allocated for RAID-3 processing is not available. This can happen if the disk array is powered up after SP memory has been removed, or when the ownership of the LUN is transferred to a peer SP that does not have enough memory. The front end Fibre Channel interface failed or is inoperable. A command failed for the reason explained in the extended status word. Unsolicited Event Log 6-47
