Message
Description
Recommended Action
Accelerator
status: Obsolete
data sensed at
reset
During reset initialization obsolete data
was found in the cache. This was due to
the drives being moved and written to by
another controller.
Nothing needs to be done. The controller will either
write the data to the drivers or discard the data
completely. Normal operations should continue.
Accelerator
status: Obsolete
data was written
to drives
During reset initialization obsolete data
was found in the cache. The 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, nothing needs to be
done. Normal operations should continue.
Accelerator
status: Obsolete
data was
discarded
During reset initialization obsolete data
was found in the cache and it was
discarded (not written to the drives).
Nothing needs to be done. Normal operations should
continue.
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(s).
Fix the problem with the drive(s). Then the controller
will be able to write the dirty data to the drives.
Accelerator
status: Dirty data
detected has
reached limit.
Cache still
enabled, but
writes no longer
being posted
The 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(s).
Fix the problem with the drive(s). Then the controller
will be able to write the dirty data to the drives and
posted write operations will be restored.
Accelerator
status: Excessive
ECC errors
detected in at
least one cache
line. As a result,
at least on 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.
Replacement of the cache should be considered. If
cache replacement is not done the remaining cache
lines should continue to operate properly.
Accelerator
status: Data in the
cache was lost
due to some
reason other than
the battery being
discharged
Data in the cache was lost, but not
because of the battery being discharged.
Check to be sure that the array accelerator is
properly seated. If the error continues you may need
to replace the array accelerator.
