MAP4920 Section-1

Procedure

  1. Did this failure occur during an install procedure?
    • Yes, go to step 2.
    • No, go to step 7.
  2. Does the serviceable event FRU list contain multiple storage enclosures?
    • Yes, go to step 3.
    • No, go to step 7.
  3. Ensure that each end of the FC-AL cables in the rack are connected (one end at the storage enclosure, the other end at the I/O enclosure device adapter card). Review the installation instructions to determine if the FC-AL cables need to be routed from the rack that you are installing and connected to another rack.

    Are the cables connected properly?

    • Yes, observe the storage enclosure LEDs and DDMs to ensure power is on. If the power is not on, review the installation instructions or contact your next level of support. If the power is on, go to step 7.
    • No, go to the next step.
  4. Use the installation instructions to connect the FC-AL cables correctly.
  5. The storage enclosures now need to have the hardware resources "harvested." This automatically occurs each time the storage facility is powered on or when a CEC enclosure is powered on. To harvest the hardware resources, perform either of the following procedures:
    • Power-cycle the storage facility.
    • Use the Storage Facility Management > storage facility > Exchange Parts option to do a pseudo part replacement of a CEC enclosure FRU (when you perform a pseudo part replacement, you do not actually replace the part, even though you use the part replacement procedure).
  6. Manually invoke the drive certify process to the DDMs in the storage enclosures that you just recabled.
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the bottom Task area, click Service Utilities > View/Certify drives. A window opens and displays the number and type of drives to be certified.
    3. The certify process can take a few hours. Continue the installation procedure during the certify process.
  7. View the list of Serviceable Events for this Storage Facility. For guidance, use MAP1210 Displaying and repairing a serviceable event

    Do you have an open serviceable event that lists a FRU that is related to the same resource in the serviceable event that sent you here? (For example, an I/O enclosure backplane, device adapter card, FC-AL cable, FCIC card, storage enclosure backplane, or DDM?)

    • Yes, repair that serviceable event first. After the repair, if you still have missing resources, return here.
    • No, go to the next step.
  8. Visually inspect the resource or FRU listed in the serviceable event that sent you here. Use the location code listed to ensure that the part is not physically missing or that it has not been installed in the wrong location during a repair. Use the following guidelines:
    • If the part is missing, repeat the install or service procedure to install the part. If an install cannot be repeated, try using the Storage Facility Management > storage facility > Exchange Parts procedure.
    • If the part was installed in the wrong location, the code has discovered it and created a resource object for it. Even after you physically remove the part, the resource object will remain. The resource object must be found and manually removed with command line access; contact your next level of support for this.
    • Even if a part is present and passes a visual inspection, replace it. To replace the part, use the serviceable event FRU list or use the Storage Facility Management > storage facility > Exchange Parts procedure.
