from some unknown reasons. (This event rarely happens. Please contact
AMCC 3ware technical support if this event occurs.)
0042 Primary DCB read error occurred
This message will be sent when the controller finds an error while reading the
primary copy of the Disk Configuration Block (DCB). The back-up copy of
the DCB will be read if this error occurs. If a valid DCB is found, the primary
DCB is re-written to rectify the errors found.
If this error occurs, we recommend verifying the unit. See “Starting a Verify
Manually” on page 153.
0043 Backup DCB read error detected
This message will be sent when the controller sees a latent error in the backup
Disk Configuration Block (DCB). A scrubbing activity will be started to
repair any sector errors on getting this error. An effort is made to read the
backup DCB even when the primary DCB is successfully read. When an error
occurs here, this is a latent error that needs to be addressed before any future
errors so this DCB is re-written with the primary copy to rectify the errors
found.
If this error occurs, we recommend verifying the unit. See “Starting a Verify
Manually” on page 153.
0044 Battery voltage is normal
The Battery Backup Unit measures and evaluates the battery pack voltage on
a continuous basis. If the voltage falls outside the acceptable range then
comes back within the acceptable range, this message will be posted to the
host.
0045 Battery voltage is low
The Battery Backup Unit measures and evaluates the battery pack voltage on
a continuous basis. If the voltage is below the warning threshold, this message
will be posted. When this event happens, the Battery Backup Unit is still able
to backup the 3ware RAID controller, but you should replace the battery.
0046 Battery voltage is high
The Battery Backup Unit measures and evaluates the battery pack voltage on
a continuous basis. If the voltage is above a warning threshold, this message
will be posted. When this event happens, the Battery backup Unit is still able
to backup the 3ware RAID controller but you should replace the battery.
