Indication
When this LED is lit, it indicates that the
controller has successfully started or restarted.
When this LED is lit, it indicates that there is
data in the cache that has not been written to a
disk or synchronized to the redundant controller
cache.
Note: Do not remove a functioning RAID
controller if the cache-dirty LED is lit.
When this LED is lit, it indicates that the XScale
memory has failed. This is based on one of the
following conditions:
v Cannot read the DIMM configuration data
v Nonrecoverable ECC failure
When this LED is off, it indicates that the XScale
memory is operating normally.
