Message Description Recommended Action
Accelerator
status: Excessive
ECC errors
detected in at
least one cache
line. As a result,
at least one
cache line is no
longer in use.
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.
Replace the cache. If cache replacement is not
done, the remaining cache lines should continue
to operate properly.
Accelerator
status: Excessive
ECC errors
detected in
multiple cache
lines. As a result,
the cache is no
longer in use.
The number of cache lines
experiencing excessive error
checking and correcting (ECC) errors
has reached a preset limit. The cache
has been shut down.
First, try reseating the cache to the controller. If
that doesn’t work, replace the cache.
Accelerator
status: Obsolete
data detected.
During reset initialization, obsolete
data was found in cache. This was
due to drives being moved and
written to by another controller.
Normal operations should continue. The
controller will either write data to the drives or
discard the data completely.
Accelerator
status: Obsolete
data was
discarded.
During reset initialization, obsolete
data was found in cache and was
discarded (not written to drives).
Normal operations should continue.
Accelerator
status: Obsolete
data was flushed
(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.
If newer data was overwritten, you may need to
restore newer data; otherwise, normal
operations should continue.
Accelerator
status:
Permanently
disabled
Array accelerator board has been
permanently disabled. It remains
disabled until it is reinitialized using
the Array Configuration Utility (ACU).
Check the Disable Code field. Run ACU to
reinitialize the array accelerator board.
Accelerator
status: Possible
data loss in
cache
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.
There is no way to determine if dirty or bad data
was in the cache and is now lost.
Accelerator
status:
Temporarily
disabled
Array accelerator board has been
temporarily disabled.
Check the Disable Code field.
Accelerator
status:
Unrecognized
status
A status was returned from the array
accelerator board that ADU does not
recognize.
Obtain the latest version of ADU.
