Procedure

  1. Select the rack model that applies:
    • 941/94E, continue at the next step.
    • 951/95E, go to step 4.
  2. Refer to the FRU list in the serviceable event that sent you here.
    1. For each DDM in the FRU list, read the location code. The location code is the special format that is used during MES and installations. An example of a location code is Rw-Sxy-P1-Dz, where:
      • w = 1–5, the rack number
      • x = 1, the front storage enclosure and x = 2, the rear storage enclosure
      • y = 1–8, the storage enclosure location, top to bottom
      • z = slot 1–16, the DDM slot location
    2. For each location code, locate the physical location by using Figure 1, Figure 2, and Figure 3.

  3. The normal serviceable event FRU replace procedure cannot be used. The code objects are not yet created because the installation failed. Continue with the following steps:
    1. Replace each DDM in the FRU list with a new DDM now. The DDM can be hot-plugged with no damage to the storage enclosure and DDM.
    2. Wait for the new DDMs to be in the ready state before you go to step 7.
  4. Refer to the FRU list in the serviceable event that sent you here.
    1. For each DDM in the FRU list, read the location code. The location code is the special format that is used during MES and installations. An example of a location code is Rw-Gx-P1-Dz, where:
      • w = 1–4, the rack number
      • x = 01–20, storage enclosure location, top to bottom
      • z = slot 1–24, the DDM slot location
    2. For each location code, locate the physical location by using Figure 4, Figure 5, and Figure 6.
      Figure 4. Rack 1-4 storage enclosure and I/O enclosure location codes (front view)

  5. The normal serviceable event FRU replace procedure cannot be used. The code objects are not yet created because the installation failed. Continue with the following steps:
    1. Replace each DDM in the FRU list with a new DDM now. The DDM can be hot-plugged with no damage to the storage enclosure and DDM.
  6. Is the DDM green activity LED indicator Callout label 1 lit solid or flashing?
    • Yes, go to the next step.
    • No, try reseating the DDM. If it still fails, replace the DDM with another new DDM. If it still fails, replace the storage enclosure midplane FRU.
      Note: You cannot use normal guided maintenance to replace the midplane because the installation failed before all the needed code objects were created. Instead, remove all power from the storage enclosure and refer to the "Exchange the storage enclosure midplane" procedure in the Exchanging Parts section of this service information center. After the new midplane is installed, reconnect all storage enclosure power.
  7. Are there any other open serviceable events for the storage enclosures that you are installing?
    • Yes, if the other serviceable event also includes SRC BE340080 or BE34004D, use this MAP to replace the listed FRUs.
    • If the other serviceable event includes a different SRC that cannot be repaired, stop and contact your next level of support.
  8. Close the open serviceable events for the storage enclosures that you are installing.
  9. Retry the storage enclosure installation procedure:
    1. Do not disconnect any of the FC-AL cables from the storage enclosures that you are installing.
    2. As you go through the installation procedure, ignore any instructions to connect the cables; they are already connected.
    3. The installation process installs the storage enclosures and provides a "FRU verification test" for the DDMs that you replaced. If the installation fails with the same SRC and DDM, contact your next level of support.
    4. Exit this procedure and complete the installation.
