Performing a slow boot by using the Advanced System Management Interface menus

You can perform a slow boot by using the Advanced System Management Interface (ASMI) menus.

In some cases, you need to perform a slow-mode boot to perform extended diagnostic testing.
Note: A slow-mode boot might produce a new reference code on the control panel or new errors in the service processor error log. When the server reports a new error code, record it for use in subsequent steps.

To perform a slow boot by using the ASMI, complete the following steps:

  1. Record any reference codes that appear on the control panel or HMC.
  2. Shut down all logical partitions and the server.
  3. In the ASMI Welcome pane, specify your user ID and password, and click Log In.
  4. Expand Power/Restart Control and click Power On/Off System.
  5. Record the settings so that you can reenter them after you complete the service actions.
  6. On the Power on/off system menu, select the following options:
    • Click Slow in the Set System Boot Speed field.
    • Click Running in the Boot to system server firmware field.
  7. Select Save Settings.
    Note: These settings will apply to all future boots. After you complete the service action, change the settings back to what you recorded in step 5.
  8. After you are done, return to the step in the procedure that caused you to perform a slow boot. This ends the procedure.
