Sometimes it happens that both pathes to a SAN LUN are not available for a short time. Because it is not possible to enable any timeouts inside the HBA driver (QLogic) you have to handle this situation a layer above. You can do it with the DM Multipath feature "queue_if_no_path". I have upgraded the HDS prioritizer to version 2.00.
