Verify the System Power Control Network (SPCN)

Use the procedures in this section to check for SPCN (System Power Control Network) errors, check for inactive enclosures, and fix any MTMS (Machine, Type, Model, and Serial Number) problems.

To verify the new configuration is functioning for an HMC managed system, go to step 1. For a system not managed by the HMC, go to step 2.

  1. If your system is managed by an HMC, use the HMC to verify that there are no 1000 9xxx errors by completing the following steps:
    1. In the navigation area of the HMC, expand Management Environment.
    2. Expand the management environment you are working with.
    3. Expand Service Applications.
    4. Select Service Focal Point.
    5. In the contents area, select Manage Serviceable Events.
    6. In the Manage Serviceable Events – Select Serviceable Events window, select the following:
      1. Open for the Serviceable Event Status.
      2. The MTMS of the server you are working with for Reporting MTMS.
      3. ALL for all other fields
    7. Click OK.
    8. Scan for any 1000 9xxx errors, and do the following:
      • If there are no errors, click Cancel to exit.
      • If there are errors, they must be corrected before continuing. If you need assistance, contact your service provider.
    9. Go to step 3.
  2. If your system is not managed by an HMC, use the service action event log to verify that there are no 1000 9xxx errors by completing the following steps:
    1. Sign on with at least service level authority.
    2. On the command line of the i5/OS® session, type strsst and press Enter.
      Tip: If you cannot get to the System Service Tools display, use function 21 from the control panel.
    3. Type your service tools user ID and service tools password on the System Service Tools (SST) Sign On display. Press Enter.
      Tip: The service tools password is case-sensitive.
    4. Select Start a Service Tool from the System Service Tools (SST) display. Press Enter.
    5. Select Hardware Service Manager from the Start a Service Tool display. Press Enter.
    6. Select Work with Service Action Event Log from the Hardware Service Manager display. Press Enter.
    7. On the Select Timeframe display, change the From: Date and Time to the desired date and time range. The suggested range is 30 days.
    8. Search for any 1000 9xxx errors, and do the following:
      • If there are no errors, press F3 to exit and return to the Hardware Service Manager display.
      • If there are errors, they must be corrected before continuing. If you need assistance, contact your service provider.
    9. Go to step 3.
  3. Verify that none of the existing expansion units with control panels have a ‘C62E’ code on the display area of the control panel. This indicates that the expansion unit is unable to communicate with the system. If one or more of them do, there is a problem with the SPCN cabling. Correct the problem before continuing.
  4. To verify that there are no inactive expansion units in the SPCN, do the following:
    1. Access the ASMI using an authority level of Administrator or Authorized service provider. See Managing the Advanced System Management Interface (ASMI) for information about using ASMI.
    2. In the ASMI navigation area, expand System Configuration and select Configure I/O Enclosures.
    3. Verify that each row has the word Active in the Status column. If any of the I/O enclosures have a status of Inactive, do one of the following:
      1. If you have already concurrently added expansion units to the system, do not invoke Clear inactive enclosures. Contact your service provider for assistance.
      2. If you are preparing to add expansion units but have not done so yet, click the Clear inactive enclosures button on this panel. Wait for the completion indication, then repeat steps 4.b and 4.c. If the problem persists, contact your service provider.
  5. Correct any temporary configuration IDs and MTMS (Machine Type, Model, and Serial Numbers) for the expansion units. If you have already concurrently added expansion units to the system, go to step 6. If you are preparing to add expansion units, but have not yet done so, go to step 7.
  6. If you have already concurrently added expansion units to the system go to Setting expansion unit configuration ID and MTMS value to verify the newly added expansion units. Then go to step 8.
  7. If you are preparing to add expansion units but have not done so yet, complete the following steps for all expansion units on the system.
    1. Access the ASMI using an authority level of Administrator or Authorized service provider. Refer to Managing the Advanced System Management Interface (ASMI) for information about using ASMI.
    2. In the ASMI navigation area, expand System Configuration and select Configure I/O Enclosures.
    3. Verify that none of the values in the Location code column are of the form UTMPx.xxx.xxxxxxx where ‘x’ may be any number 0-9 or character A-Z. If any of the expansion units have a Location Code with the format UTMPx.xxx.xxxxxxx, refer to Setting expansion unit configuration ID and MTMS value for instructions on how to correct it.
  8. Return to the procedure that sent you here.
