Description
Extended status identifies unit number. This message is
logged once for each CRU in a LUN at the completion of a
Bind operation.
Extended status identifies unit number. This message is
logged once for each CRU in a LUN at the completion of an
Unbind.
Extended status identifies fuse number. This message is
logged once at the completion of each powerup for any bad
fuse detected by the SP.
Extended status identifies SCSI bus number. This message is
logged once at the completion of each powerup for any SCSI
bus which the SP detects as having an insufficient
"TERMPWR" voltage level. This event code is only used by
SPs that do not themselves source termpower into the bus
(for example, Telmo).
The given FRU's current physical position in the disk array
chassis does not match its expected position (which is set at
the time the FRU is bound into a LUN).
The SP started dumping the storage system cache data to the
cache vault disks.
The SP finished dumping the storage system cache to the
cache vault disks.
The SP is in the process of enabling the cache for use on host
data.
Storage-system caching was disabled by the disk array or
system operator. The disk array disables caching if the BBU is
not fully charged or an SP, cache vault disk or fan fails; see
error 0x908.
After an AC power failure, the disk array dumped the cache to
the vault and turned off power to the BBU (to minimize drain
on the BBU).
The disk array is allowed to shut down the BBU in order to test
it.
BBU shutdown testing is disabled on this disk array.
The BBU is beginning a shutdown test cycle.
In preparation for its weekly BBU test cycle, the disk array
dumped its cache data. This message is followed by a 0x663
message.
