Set DCU Failover Control for System

On SPARC servers, such as M8 series servers, you can set system-wide DCU failover control as of Oracle ILOM firmware version 4.0.1.x and later. By default, the system DCU failover control is automated by Oracle ILOM. However, during service operations such as hot-plug insertion or removal it might be helpful to suspend the automated failover control by Oracle ILOM. For these instances, the DCUs Failover control can be set to Manual. For further details, follow these instructions:

  1. To set DCU system failover control, perform one of the following:
    • Web: From the active SP web interface, click ILOM Administration > Configuration Management > DCUs.

      In the Failover box, select Auto or Manual.

      For a description of each option, see DCU System Failover Properties.

      - OR -

    • CLI: From the active SP CLI, type:

      set /System/DCUs failover= Auto|Manual

      For a description of each option, see DCU System Failover Properties.
