  2. Power off the storage facility.
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the bottom Task area, click Service Utilities > Storage Facility Power Control. The Power Control window opens.
      Figure 3. Window: Power Control
      Window: Power Control
    3. In the upper left, ensure that the Current Remote Power Control Mode is set to Manual.
      Note: If the mode is not set to Manual, select Manual Power Mode from the Power Control Modes section.
    4. In the Change Storage Facility Power State section, click Power OFF Storage Facility, and then click OK.
    5. Click OK to confirm the update for the Power Control Settings.

      The storage facility will now begin the power off sequence.

  3. Wait a maximum of 10 minutes for the storage facility power off sequence to complete.

    The sequence is complete when the storage enclosures/DDMs are off, and the green LED is slow flashing on both CEC enclosure control panels.

    Did the storage facility power off?

    • Yes, go to step 5.
    • No, go to the next step.
  4. The storage facility has not powered off after waiting 10 minutes.
    1. Wait a maximum of 30 minutes and then contact your next level of support.
      Notes:
      • If the power-off sequence encountered a problem, it can take up to 90 minutes for a successful power-off.
      • If the storage facility did not power off at all, it may be possible to check for and repair any open serviceable events related to rack power or the CEC enclosures.
    2. DO NOT force the power off by using the red UEPO switch or by any other method. If you force the power off, you will need to contact your next level of support to help you recover the storage facility.
  5. CPD or complete power down of the storage facility is a state where the mainline power cables might be disconnected after the customer switched off his or her mainline power circuit breakers. Do you need to do a complete power down (CPD) of the storage facility?
    • Yes, go to the next step.
    • No, exit this MAP.
  6. Shut down the management console as follows:
    1. From the navigation area, click HMC Management.
    2. In the right work area, go to the Operations section and click Shut Down or Restart. The Shutdown or Restart window opens.
    3. Select Shutdown HMC, then click OK.
    4. Wait for the HMC to power off then go to the next step.
  7. Do you need to remove all customer power from this storage facility?
    • Yes, go to the next step.
    • No, exit this procedure.
  8. Is the storage facility a 242x model 961?
    • Yes, go to step 12.
    • No, go to step 9.
  9. At the rear of each rack in the storage facility, switch off the mainline power CB00 Callout label 1 (Figure 4) on both primary power supplies (PPS).
    Figure 4. Rear view of PPS showing CB00
    Remove the AC Mainline Power Cord
  10. Verify that all input power has been removed from each rack. At the front of both PPSs in each rack, ensure the Callout label 2 AC INPUT GOOD LED indicator is off.
    Note: If the LED is lit, CB00 is not switched off.
    In Figure 5, the Model 941/94E is shown; the Model 951/95E is similar.

  11. Go to step 14.
  12. At the rear of each rack in the storage facility, set the main line switch CB1 Callout label 8 (Figure 6) to Off (down) on both DC-UPS.
    Figure 6. DC-UPS DC supply unit (DSU)
    DC-UPS DC supply unit (DSU)
  13. Verify that all input power has been removed from each rack. At the rear of both DC-UPSs in each rack, ensure the Callout label 2 LOCAL AC (input) LED indicator is off. See Figure 6.
    Note: If the LED is lit, CB1 is not switched off.
  14. If you plan to disconnect the mainline power cords, ensure the customer has switched off the circuit breaker for each mainline power cord to be disconnected.

MAP2470 Section-3 Power on the storage facility

Procedure

  1. Is the storage facility a 242x model 961?
    • Yes, go to step 4.
    • No, go to step 2.
  2. Observe the front of each rack in the storage facility. Are the LEDs for AC INPUT GOOD Callout label 2 and UEPO LOOP GOOD Callout label 3 on each PPS lit solid? See Figure 5.
    • Yes, go to the next step.
    • No. A rack can power on successfully with only one of the two redundant PPSs operational. However, it is best to have both PPSs in each rack operational before you power on the storage facility. Do the following:
      1. At the rear of the rack, ensure that the mainline power cables are connected to the PPS and also to the customer power source.
      2. Ensure that the customer circuit breaker for each mainline power cable source is set to on.
      3. At the rear of each PPS, ensure that each mainline power CB00 is switched to on (up).
      4. If you cannot find the problem and only one PPS in the rack is not operational, wait and fix it after the storage facility is powered on. There should be an open serviceable event for the problem.
  3. Go to step 5.
  4. Observe the rear of each rack in the storage facility. Is the LOCAL AC (input) Callout label 2 LED indicator on each DC-UPS lit solid? See Figure 6.
    • Yes, go to the next step.
    • No. A rack can power on successfully with only one of the two redundant DC-UPSs operational. However, it is best to have both DC-UPSs in each rack operational before you power on the storage facility. Do the following:
      1. At the rear of the rack, ensure that the mainline power cables are connected to the DC-UPSs and also to the customer power source.
      2. Ensure that the customer circuit breaker for each mainline power cable source is set to on.
      3. At the rear of each DC-UPS, ensure that each main line switch CB1 is switched to on (up).
      4. If you cannot find the problem and only one DC-UPS in the rack is not operational, wait and fix it after the storage facility is powered on. There should be an open serviceable event for the problem.
  5. Ensure that the management console has powered on. If not, you will need to manually power it on.
  6. Power on the storage facility.
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the bottom Task area, click Service Utilities > Storage Facility Power Control. The Power Control window opens.
      Figure 7. Window: Power Control
      Window: Power Control
    3. At the top of the screen, ensure that the Current Power Control Mode is set to Manual.
      Note: If the mode is not set to Manual, select Manual Power Mode from the Power Control Modes section.
    4. In the Change Storage Facility Power State section, click Power ON Storage Facility, and then click OK.
    5. Click OK to confirm the update for the Power Control Settings.

      The storage facility will now begin the power-on sequence.

      The power-on process can take up to 30 minutes for the LPARs to be ready for customer use.

  7. Remember to use the Power Control Modes to restore the mode back to its original setting.
