HP Servers Troubleshooting Guide
Description
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.
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.
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.
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.
During reset initialization,
obsolete data was found in the
cache due to the drives being
moved and written to by
another controller.

Recommended Action
Resolve the problem with the
drive or drives. The controller
can then write the dirty data to
the drives. Posted-writes
operations are restored.
Resolve the problem with the
drive or drives. The controller
can then write the dirty data to
the drives.
Consider replacing the cache.
If cache replacement is not
done, the remaining cache
lines generally continue to
operate properly.
Try reseating the cache to the
controller. If that does not
work, replace the cache.
Normal operation should
continue. The controller either
writes the data to the drives or
discards the data completely.
