Cause. The return code received is not as expected; usually a value of zero is
expected.
Effect. An error is returned to the client file system, typically resulting in recovery by
ending the Direct Bulk I/O session and reverting to normal I/O.
Recovery. This event must be extremely rare; any occurrence indicates that your
service provider must be notified even though no service action is required for
recovery. Frequent occurrence of this event might suggest that Direct Bulk I/O must be
disabled using SCF in order to minimize system performance impact.
