Message
Description
Recommended Action
Accelerator status: Dirty data
detected has reached limit.
Cache still enabled, but writes
no longer being posted.
Number of cache lines
containing dirty data that
cannot be flushed (written) to
the drives has reached a
preset limit. The cache is still
enabled, but writes are no
longer being posted. This
problem usually occurs when
there is a problem with the
drive or drives.
Resolve the problem with the
drive or drives. The controller
can then write the dirty data to
the drives. Posted-writes
operations are restored.
Accelerator status: Dirty data
detected. Unable to write dirty
data to drives
At least one cache line
contains dirty data that the
controller has been unable to
flush (write) to the drives. This
problem usually occurs when
there is a problem with the
drive or drives.
Resolve the problem with the
drive or drives. The controller
can then write the dirty data to
the drives.
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 error checking and
correcting (ECC) errors
detected during use of the
memory associated with that
cache line.
Consider replacing the cache.
If cache replacement is not
done, the remaining cache
lines generally 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. Therefore, the cache has
been shut down.
Try reseating the cache to the
controller. If that does not
work, replace the cache.
Accelerator status: Obsolete
data detected
During reset initialization,
obsolete data was found in the
cache due to the drives being
moved and written to by
another controller.
Normal operation should
continue. The controller either
writes the data to the drives or
discards the data completely.
