HP A3550A - High Availability Disk Arrays Model 20 Storage Enclosure User Manual page 311

Event code Description
0x924 Host Vault Disks Scrambled. The SP found the vault disks containing the cache
image to be in different order than when the cache image was dumped to disk.
This means the disks were swapped at power down. The disks must be restored
to their original order before the SP can load the cache image.

Event code Description
0xA02 Failed SCSI bus. An internal SCSI bus has failed. The CRU number displayed
corresponds to the bus number (A0 means bus A, B0 means bus B, and so on).
The failure resulted from a bad cable or cable connection, bad terminator, bad
SCSI chip on an SP or a bad device.
0xA05 NOVRAM Uninitialized. The non-volatile memory on the SP is uninitialized. No
host I/O can occur.
0xA06 Chassis Shutdown. An overtemperature situation could not be corrected. All
drives in the chassis will be shut down. The problem must be corrected before
powering up again.
0xA07 Drive Failure. The disk drive has failed and can no longer be accessed.
0xA08 Data Base Sync Error. The SP cannot determine the correct logical configuration
of all units in this disk array. Some units may be unusable.
0xA09 Drive too Small. A replacement drive has been inserted and does not have
adequate capacity for a rebuild operation to begin.
0xA11 Peer Controller Removed. This SP's peer controller is no longer responding to
queries from this SP following a period of time where the peer was known
present.
0xA12 Cache Memory Hard Error. The disk array detected a hard error in SP memory
in a disk array with non-mirrored caching. This error does not apply to a disk
array with two SPs.
0xA13 CRU Type Unsupported. This type of disk CRU is not supported by the current
SP software. The disk cannot be bound or used for host I/O.
