Description
At least one line in the cache is no
longer in use due to excessive ECC
errors detected during use of the
memory associated with that cache
line.
During reset initialization, obsolete
data was found in cache. Due to
drives being moved and written to by
another controller.
During reset initialization obsolete
data was found in cache and was
discarded (not written to drives).
During reset initialization obsolete
data was found in cache. Obsolete
data was written to the drives, but
newer data may have been
overwritten.
Array accelerator board has been
permanently disabled. It remains
disabled until it is reinitialized using
the Array Configuration Utility (ACU).
Possible data loss detected during
power up due to all batteries being
below sufficient voltage level and no
presence of identification signatures
on the array accelerator board.
Array accelerator board has been
temporarily disabled.
A status returned from the array
accelerator board that the ADU does
not recognize.
Valid data was found in posted write
memory at reinitialization. Data will
be flushed to disk.
Catastrophic problem with array
accelerator board. Refer to other
messages on Diagnostics screen for
exact meaning of this message.
Recommended Action
Replacement of cache should be considered. If
cache replacement is not done, remaining
cache lines should continue to operate properly.
Normal operations should continue. The
controller either writes data to the drives or
discards the data completely.
Normal operations should continue.
If newer data was overwritten, you may need to
restore newer data; otherwise, normal
operations should continue.
Check the Disable Code field. Run Array
Configuration Utility (ACU) to reinitialize the
array accelerator board.
There is no way to determine if dirty or bad data
was in the cache and is now lost.
Check the Disable Code field.
Obtain the latest version of the ADU.
Not an error or data loss condition. No action
required.
Replace the array accelerator board.
