HP A3550A - High Availability Disk Arrays Model 20 Storage Enclosure User Manual page 310

Event code Description
0x908 Hardware Fault - Cache disabling. Some hardware condition has caused the SP
to disable the cache. The problem might be:
– BBU is not ready (not present and fully charged)
– One or more vault disks is missing or being rebuilt
– Fan fault occurred, or
– SP failed
0x909 Cache Dump Failed. A fault caused the disk array to try to dump the vault. The
cache dump failed because two or more vault disks are missing or have failed.
0x90A Assign Fails - Cache Dirty Unit. The SP cannot assign this unit, because it is
marked as having cached data outstanding, and the SP has no access to the
data.
0x90B Controller Cannot Initialize Cache. Some hardware or software failure occurred
when the SP attempted to initialize a new cache image.
0x90C Cache Image Exceeds Memory Size. This SP is incapable of loading the saved
cache data image due to insufficient cache memory size.
0x90D BBU Removed. The BBU in this disk array has been removed.
0x90E BBU Disabled. The BBU in this disk array has failed its internal selftest.
0x90F Cache Recovered With Errors. A non-mirrored cache recovery failed to recover
the cache pages for some, but not all, cached LUNs. It does not apply to a disk
array with two SPs.
0x910 Cache Recovery Failed. A non-mirrored cache failed to recover information for
all cached LUNs. It does not apply to a disk array with two SPs.
0x920 Hard Media Error. This disk has reported a media defect with could not be
cleared by the SP.
0x921 Host Vault Load Failed. The SP encountered multiple errors while attempting to
load the cache image from disk. This message may indicate multiple drive
failures.
0x922 Host Vault Load Inconsistent. The SP found inconsistencies in the card image
on the disk. This may indicate a failure or abort of the cache dump.
0x923 Host Vault Load Failed Bitmap Ok. 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
LUN with write-cached pages will be inaccessible and must be rebound. To
identify such a LUN, read message 0x90A in this table.
