Determining cable problems

Complete this task to determine if a cable is the cause of a resource fault event.

Before you can begin problem determination, you must have another cable of the same type as the cable that might be causing the fault event.
Note: For cabling information, see Routing the cables.
The following resources use cables to connect to other hosts, enclosures, networks, or power sources:
  1. Use the light path indicators or the DS Storage Manager to find the resource that has experienced a fault.
  2. If necessary, ensure that the external item that is connected to your enclosure, such as a host system or another enclosure, is offline.
  3. Disconnect the cable from the external item.
  4. Disconnect the cable from the server or expansion enclosure.
  5. Reconnect the replacement cable to the server or expansion enclosure.
  6. Reconnect the replacement cable to the external item.
  7. Follow the proper procedure to bring the external item online, if necessary.
  8. Watch the problem logs to see if the fault event occurs again.
    • If the fault event does not occur again, the cable was causing the problem.
    • If the fault event does occur again, the original cable was not the cause of the problem and you must replace the resource.
  9. Find and close the problem log entry for the resource through the DS Storage Manager.
  10. Bring the resource online.
Dispose of the cables that were determined to be the cause of the fault. Keep the cables that were not the cause of the fault for later use.
