Connecting FC-AL cables, Rack-4 to Rack-2

You are here to install one or more pairs of storage enclosures in Rack-4.

Procedure

  1. Determine the LIC bundle VRMF of this storage facility. Perform the following steps from the existing management console.
    1. From the navigation area, click Updates.
    2. From the right work area, select the check box for the appropriate storage facility. The bottom Task area displays a list of tasks you can select.
    3. Click Display Storage Facility Code Levels. An Action Panel displays the code levels.
    4. Find Package: HMC, MTMS: XXXXXXX*XXXXXXX and find the Bundle VRMF: xx.xx.xx.xx beneath it. There might be more than one bundle under install history; select the top line which is the latest bundle.
    5. Write down the LIC bundle VRMF.
  2. Begin the installation of the Rack-4 storage enclosures at the HMC.
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the bottom Task area, click MES Install/Remove > Install Storage Enclosure or Drives. For earlier versions, the menu item is Install Storage Enclosure or DDMs.
    3. The Install window opens and asks if you were sent from the installation or MES instructions. Click Yes.
    4. The Single Choice Message Box window opens and prompts "Select the component or enclosure you would like to install." Select Install Storage Enclosures and then click Submit.
    5. A subsequent Single Choice Message Box window opens that prompts "Select the Storage Facility Image you want to assign the storage enclosures to."
    6. Select the storage facility image and then click Submit.
  3. Storage enclosures on multiple DA pairs can be installed at the same time. Complete the following steps:
    1. If the informational DaPairsPanel displays, click OK.
    2. The Select Device Adapter Pair window displays a list of DA pairs available for additional Rack-4 storage enclosures on the selected storage facility image.
    3. At the front of Rack-4 find all the storage enclosures that you have not yet cabled and installed.
    4. Use Figure 1 to determine their Rack-3 storage enclosure location codes (ex: R4-S11).
      Figure 1. Storage enclosures in expansion rack without I/O enclosures

    5. Use Table 1 to determine the DA Pair IDs the storage enclosures connect to.

      For simplicity, Table 1 lists only the front storage enclosures. However, for each front storage enclosure there is a corresponding rear storage enclosure that creates the storage enclosure pair. For example, R4-S11 is paired with R4-S21.

      Table 1. Rack-4 storage enclosure pairs and DA pair IDs
      If Rack-4 storage enclosure: And Rack-4 storage enclosure: You are installing x pair(s) of storage enclosures: They connect to DA Pair ID
      R4-S11 has DDMs R4-S12 has DDMs 2 pairs 6
      R4-S11 has DDMs R4-S12 is empty 1 pair
      R4-S11 is empty R4-S12 is empty 0 pair
       
      R4-S13 has DDMs R4-S14 has DDMs 2 pairs 4
      R4-S13 has DDMs R4-S14 is empty 1 pair
      R4-S13 is empty R4-S14 is empty 0 pair
       
      R4-S15 has DDMs R4-S16 has DDMs 2 pairs 7
      R4-S15 has DDMs R4-S15 has DDMs 1 pair
      R4-15 is empty R4-S16 is empty 0 pair
       
      R4-S17 has DDMs R4-S18 has DDMs 2 pairs 5
      R4-S17 has DDMs R4-S18 has DDMs 1 pair
      R4-S17 is empty R4-S18 is empty 0 pair
    6. At the HMC screen, select all the DA Pair IDs that will have storage enclosures installed and click OK.
    7. The Select Storage Enclosure Pairs window displays the status of the storage enclosure positions for each DA pair ID.
    8. Multi-select each storage enclosure position you will install. Each of those positions should display the enclosure status "Available for Install". Then click OK.
      Note: If a position to be installed does not display "Available for Install," it may already be installed. If it is not already installed, stop and contact next level of support.
    9. An Action Panel window displays the physical location codes of the storage enclosures to be connected. If the location codes are correct, click OK.
      Note: Each pair (for example, R4-S13 R4-S23) is one storage enclosure at the front of the rack and one storage enclosure at the rear of the rack.
    10. Wait for the TextandNextButtonBean window to display
    11. The HMC displays the Rack-4 storage enclosure physical location codes to be installed.
    12. DO NOT click Next until directed in a later step.
    13. Using the HMC-displayed physical location code, refer to Figure 1 to determine the location of each storage enclosure being installed in the rack.
    14. Go to the next step.
  4. For each Rack-4 storage enclosure physical location code displayed by the HMC, ensure the four FC-AL cables are still connected to the T1 & T2 connectors (labeled J1 & J2 on the sheet metal) on both FCIC cards in the Rack-4 storage enclosure being installed. See Figure 2.
    Note: These cable ends should not have been disconnected as part of this installation procedure.

  6. Are you here to install R4-S11, R4-S15, R4-S21, or R4-S25?
    • Yes, the FC-AL cable bundle needs to be routed to Rack-2, go to the next step.
    • No, the FC-AL cable bundle should have already been routed to Rack-2, go to step 8.
    Note: If the cable bundle was not already routed, then the sequence of installing the Rack-4 storage enclosures from top to bottom was not followed. Go to step 7.
  7. This step routes (but does not connect) the loose end of a Rack-4 FC-AL cable bundle to storage enclosures in Rack-2. DO NOT connect the cables until directed in the next step, as it will cause installation errors.
    Notes:
    • The loose end of the cable bundle has four sub-bundles of two cables each. Two sub-bundles will be routed to the left side of the storage enclosures and two sub-bundles will be routed to the right side of the storage enclosures.
    • Use Table 2 columns two and three to determine the Rack-2 storage enclosure locations that the FC-AL cables will be connected to.
    • Use Figure 3 to determine the Rack-2 storage enclosure to route the FC-AL cable bundle to. The cable bundle consists of 4 blue FC-AL cables.

    1. Find the loose end of the FC-AL cable bundle in Rack-4 that needs to be routed to Rack-2. The loose ends of the individual cables are pre-labeled with the physical location code of the enclosure and connectors they will connect to. Find the rack number label located where the cable assembly is bundled together, within 60 cm (24 in.) of the connectors. See Figure 4. Use Figure 3 and Figure 6 to match the cable labels to the Rack-2 locations.
    2. Route, but do not connect, the one cable bundle to the storage enclosure in Rack-2. See Figure 5 for an example of routing the cable bundle through the holes at the top of the racks.
      Figure 5. Mechanical routing of the FC-AL cables (rack-to-rack)

  9. This step routes and connects the short FC-AL cables that go between two Rack-4 storage enclosures (one below the other) as noted in Table 3.
    1. Use Table 3 columns two and three to determine the Rack-4 storage enclosure locations to connect the FC-AL cables to.
      Figure 7. Storage enclosures in expansion rack with or without I/O enclosures

    2. Connect each of the four blue FC-AL cables to the Rack-4 I/O enclosure connector determined in columns two and three in Table 3. See Figure 7.
    3. Go to the next step.
  10. You have already selected all the storage enclosures to be installed at one time. Return to the HMC and click Next.
  11. The HMC automatically initializes the storage facility image the storage enclosures are being installed to.
    Note: The times listed are for a fully populated rack.
    The HMC displays:

    Task in Progress...Powering on the FRU(s)
    Verification Progress...Verification progress:
    Task in Progress...Activating the system     (maximum of 60 minutes)
    Task in Progress...Verifying system
    Verification Progress...Verification progress:     (maximum of 45 minutes)
    Task in Progress...Activating applications(s)       (maximum of 85 minutes)

    When the HMC is finished, it displays:

    Service action is complete
    Service action is ending...

    When the HMC directs you back to the installation instructions, go to the next step.

  12. Have all storage enclosures with DDMs in Rack-4 been installed?
    • Yes, go to the next step.
    • No, return to step 1 to install the remaining storage enclosures.
  13. Display and repair any open serviceable events related to this expansion rack.
  14. View the storage facility state, refer to MAP1100 View storage facility state (end of call).
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the bottom Task area, click Service Utilities > View Storage Facility State. A window displays the status (passed/failed) of 25 or more system checks. Figure 8 is an example.
    3. All status fields should display as PASSED except for the following.
      • If the Resources State result is "Failed", select it and then click Details. If the Drive state is "5 (Certifying)", this is normal and you should go to the next step.
      • If other checks are failed, select it and then click Details. They should be fixed before going to the next step. If needed, call the next level of support.
      Note: If the Large File Transfer (the tenth System Check Type status from the top) displays as FAILED, the remaining System Check Types below it cannot be displayed. Contact the next level of support.
