The description for this event should actually read:
Reset to device \Device\RaidPort1 was issued.
See the information for event id 129 from HpCISSs2, it may be applicable for this warning as well.
The event ID 129 can be reported from both QLogic storport and Emulex storport drivers. Event ID 129 is actually a Microsoft port driver event detecting an I/O timeout or a delay in the response with its target devices. It is not a QLogic or Emulex error and it does not indicate that the HBA or HBA driver is at fault. This issue has been found usually as a result of a bad switch cable connection to a storage. This caused a high latency period in access to LUNs, and thus, caused delays in I/O to the point where Exchange could fail. We have also seen similar instances of the Event ID 129 affecting SQL and Oracle applications on the storage. From past cases, the problem can be caused by the switch port itself/Gbic, cable seating on the storage array or the switch, or possible Gbic on the storage array.
