Adding an I/O expansion unit with the system powered on

Learn about adding an input/output (I/O) expansion unit to the system with the system powered on.

Important: To use the following procedure to add I/O expansion units to the system, your configuration must meet one of the following requirements:
  • Your system is managed by an IBM® Hardware Management Console (HMC).
  • Your system is not managed by an HMC, but has only one partition, and that partition is running the IBM i operating system.
If your configuration does not meet any of these requirements, you must add your I/O expansion unit by completing the procedure at Adding an I/O expansion unit with the system powered off.
Prerequisites: If you did not review the information in Overview for I/O expansion units and Preparing to add an I/O expansion unit, do so now.
Note: Steps in this topic require you to have connector information for the hardware in your configuration. For details about expansion unit or system connector locations, see Connector locations.

To add an I/O expansion unit to the system with the system powered on, complete the following steps:

  1. Verify the existing 12X configuration by choosing one of the following options.
    Important: Any problems that you discover with the 12X loops in this step must be corrected before you continue with the procedure.
    • If your system is managed by an HMC, see Verifying the 12X loops with an HMC
      Tip: This task includes a step to verify the status of the links in the 12X loops. When you are instructed to use the View Hardware Topology task, you can click Save to save the current hardware topology. Use this action to compare the topology that existed before the expansion unit was added with the topology that was created by adding the expansion unit.
    • If your system is not managed by an HMC, see Verifying the 12X loops without an HMC.
  2. Verify the system power control network (SPCN). For instructions, see Verifying the system power control network.
    Important: Any problems that you discover with the SPCN in this step must be corrected before you continue with the procedure.
  3. Set the SPCN Firmware Update Policy to prevent firmware updates over the serial SPCN interface by completing the following steps.
    Note: The SPCN Firmware Update Policy controls when and how SPCN firmware on expansion units is updated. The default setting for the SPCN Firmware Update Policy is Enabled. This setting allows for firmware updates to be completed over the 12X interface whenever an update is required and does not allow updates over the slower serial SPCN interface.
    1. Access the Advanced System Management Interface (ASMI) by using an authority level of administrator or authorized service provider. For instructions, see Managing the Advanced System Management Interface.
    2. In the ASMI navigation area, expand System Configuration and select Configure I/O Enclosures.
      1. If the SPCN Firmware Update Policy shows Expanded, record the current setting so that you can restore it later, and then, change the setting to Enabled.
      2. If the SPCN Firmware Update Policy shows Enabled or Disabled, continue without changing the setting.
    3. Check to see whether an SPCN firmware update is in progress and choose one of the following options.
      Note: An SPCN firmware update is in progress if the Power Control Network Firmware Update Status column shows In Progress and displays the percentage that is completed.
      • If an SPCN firmware update is in progress, continue with step 4.
      • If an SPCN firmware update is not in progress, continue with step 5.
  4. Check the Power Control Network Firmware Update Status column to determine the type of update that is in progress, and then, choose one of the following options:
    • If the SPCN firmware update is a High Speed Link (HSL) update, wait for the update to complete before you continue. An HSL update completes quickly. To determine when the update is complete, select Configure I/O Enclosures every 15 – 30 seconds until Not Required is displayed in the Power Control Network Firmware Update Status column. Do not click Back or Refresh on the browser to monitor the status.
    • If the SPCN firmware update is a serial update, choose one of the following options:
      • Wait for the update to complete. A serial update can take 20 minutes or more depending on how many expansion units are in the configuration. To determine when the update is complete, select Configure I/O Enclosures every 15 – 30 seconds until Not Required is displayed in the Power Control Network Firmware Update Status column. Do not click Back or Refresh on the browser to monitor the status.
      • Stop the update by completing the following steps:
        Note: The update is restarted from the beginning later in the procedure.
        1. Click Stop SPCN Firmware Update in the Configure I/O Enclosures window.
        2. Click Configure I/O Enclosures every 15 - 30 seconds until Pending is displayed in the Power Control Network Firmware Update Status column. Do not use click the Back or Refresh on the browser to monitor the status.
  5. If the system has a rear cover, remove or open it.
  6. Record the current date and time for use later in the procedure when you check for serviceable events.
  7. Connect the expansion unit with 12X cables. For instructions, see Connecting expansion units with 12X cables.
    Note: When you connect an expansion unit in an existing 12X loop with the system powered on, serviceable events and informational logs might be generated when you disconnect and reconnect cables. This behavior is normal and is covered later in the procedure.
  8. Connect the expansion unit with SPCN cables. For instructions, see Connecting expansion units with SPCN cables.
    Note: When you connect an expansion unit in an existing SPCN loop with the system powered on, serviceable events and informational logs might be generated when you disconnect and reconnect cables. This behavior is normal and is covered later in the procedure.
  9. Connect the power cables for the expansion unit that you are installing. The expansion unit powers on automatically when the power cables are connected.
    Important: Ensure that you plug the power cable into the power source before you connect it into the power supply of the expansion unit.
  10. Wait for the green power indicator on the control panel of the expansion unit to light solid. This action might take 1 - 10 minutes. During this time, a yellow attention indicator might be lit on the control panel of the expansion unit. After the green power indicator is lit on the control panel, wait 10 extra minutes for hardware initialization to complete before you proceed with the installation.
  11. Verify the SPCN configuration by completing the following steps.
    1. Read and understand the following information about reference codes that might be generated when an expansion unit is added while the system is powered on to firmware standby state.
      Note: When an expansion unit is added while the system is powered on, it is normal for error logs and event logs to be created with the following SPCN-related reference codes. The number and combination of these logs is dependent on the configuration.

      Logs with the following reference codes can be ignored during this verification step if their time stamps indicate that they occurred during the add procedure and the resources that they refer to were involved in the procedure.

      • 10009133: The 12X loop was disrupted. This reference code appears in an informational log.
      • 10009135: The SPCN loop was opened. This reference code might appear in a serviceable event or an informational log.
      • 10009136: An SPCN firmware update was stopped. This reference code appears in an informational log.
