Correcting the managed system operating state

Use this procedure to correct the managed system state.

Use these procedures to put the managed system back to a correct state. Select the state you are currently receiving:

No Connection state

In the No Connection state, the HMC is not connected, or the handshake with the managed system failed. Perform the following steps:

  1. Ensure the network setting is correctly set up on the HMC. You can verify this by pinging the HMC.
  2. Ensure the network setting is correct on the managed system. Verify this by opening an ASMI session through the web browser and pointing at the managed system.
  3. Perform the reset or remove connection task on the HMC:
    1. In the navigation area, select Server and Partition > Server Management.
    2. In the Content area, right-click the managed system and select the Reset or Remove Connection.
    3. Select Reset Connection, then click OK.
    4. Wait for 5 minutes for the HMC to re-establish contacts.
  4. Check the control panel on the managed system to verify that the power is on.
    1. If the power light indicates that there is no power on the managed system control panel, see Beginning problem analysis for details.
    2. After the power is restored, wait 5 minutes for the service processor to re-IPL and the HMC to re-establish contact. If the HMC can access partitions using a virtual terminal (VTERM) but the state is still No Connection, contact your next level of support or your hardware service provider.
  5. If the power indicator is on, wait 5 minutes for the HMC to attempt to reestablish contact. The service processor in the managed system might be in the process of turning power on. If partitions no longer respond, the system power is off.
  6. From a telnet session from another system, attempt to ping or contact active partitions on this managed system.
    If the partitions are active, perform the following steps:
    1. Verify that the HMC and the flexible service processor are correctly connected to your Ethernet network, and that your Ethernet network is functioning correctly. For more information, see Cabling the HMC in the Installing hardware topic.
    2. Restart the HMC.
    3. Reset the service processor. See Resetting the service processor.
  7. If the managed system is running, and restarting the HMC did not resolve the problem, contact your next level of support or your hardware service provider.

Incomplete state

In the Incomplete state, the HMC failed to get all of the necessary information from the managed system. Perform the following steps:

  1. In the contents area, select the managed system.
  2. From the menu, click Selected > Rebuild Managed System. If the state goes to Recovery, see Recovery state. If the state does not go to Recovery, continue with the next step.
  3. Reset the connection from HMC. See Resetting the managed system connection from the HMC. If it still fails, continue with the next step.
    Note: Step 4 might take several minutes to complete.
  4. Restart the HMC. Choose from the following options:
    • If the state goes to Recovery, see Recovery state.
    • If the state remains Incomplete, perform the following steps:
      1. Verify that there is a redundant HMC.
      2. Verify that no one is entering commands from the alternate HMC.
      3. Repeat step 1. If it still fails, continue with the next step.
  5. Verify that the HMC and the flexible service processor are correctly connected to your Ethernet network, and that your Ethernet network is functioning correctly. For more information, see Cabling the HMC in the Installing hardware topic.
  6. Reset the service processor. See Resetting the service processor.
  7. If the problem persists, contact your next level of support or your hardware service provider.

Recovery state

In the Recovery state, the save area in service processor is not synchronized with the HMC Database. Perform the following steps:
  1. Recover partition data. See Recovering partition data on a managed system for details. Then return here and continue with the next step.
  2. After restoring profile data, choose the option that describes what happened:
  3. If the problem persists, contact your next level of support or your hardware service provider.

Error state

The Error state automatically generates a call to the service support center if the function is enabled. If the function is not enabled, contact your next level of support or your hardware service provider.
