Description
A background check on the correctness of parity information
has begun on the physical unit of which this drive is a
member.
A background checkpoint verification of the accuracy and
completeness of the parity check data in a RAID-5, RAID-3,
RAID-1 or RAID-1/0 LUN has been completed.
The fans were disabled because the fan pack door was
opened. The disk array shuts down if the fans are not
operational within two minutes.
The fans were enabled after the fan pack door was closed.
The disk array has detected that a fan pack has been installed
or replaced.
The disk array has detected that a VSC has been installed or
replaced.
The disk array has detected that an AC Box has been
installed.
The disk array has detected an increase in a fan's speed,
perhaps because the temperature rose or another fan failed.
The disk array has detected that the fan speed has returned to
normal.
The SP has detected an inconsistency in the sector based
check codes. An 0x800 code with more explicit information
usually follows this code, for example, 0x852 Hard Read
Checksum Error.
The Battery Backup Unit in this disk array is recharging.
The Battery Backup Unit in this disk array is enabled for use.
The disk array has enabled the on-board cache. Caching
operations will occur as defined for the caching environment.
A background rebuild operation has aborted prior to
completing the entire disk.
A background verify operation has been terminated due to an
abnormal event, such as the failure of one of the disks in the
LUN.
This SP has just detected its peer SP, following a period of
time in which the peer was not present in the chassis.
This SP has been informed by its peer SP that the peer has
completed its power-up initialization sequence.
