Advanced Configuration Tasks › Load a System Image

Load a System Image

The region loads a system image during region initialization. During operation, you may need to change the system image by loading another image.

Note: When you request to load a system image, the $RMEXSTR exit NCL procedure is executed before the starting process. This procedure may be customized at your site to perform any required tasks before any automated resources are started. The starting process cannot proceed if the exit sets a non-zero return code.

To load a system image

  1. Enter /RADMIN.I at the prompt.

    The System Image Definition Menu appears.

  2. Select the type of system image that you want to load.

    The System Image List appears.

  3. Enter L beside the system image that you want to load.

    The LOAD Command Parameter Specification panel appears.

  4. Complete the following fields:
    SysName to be Loaded

    Enter ? and select a system image from the displayed prompt list.

    Global Automation Mode

    Specify the global operation mode for your system image.

    Perform COLD Start?

    If the Checkpoint Restart Status field is set to ACTIVE, you can enter NO in the Perform COLD Start? field to specify a warm load.

  5. Press F6 (Action) to load the system image.

    The Command Confirmation panel appears.

  6. Enter CONFIRM in the Response field.

    The system image is loaded.

Important! Resources that are monitored by the region are defined to the system image. Loading a system image affects all users of this region.

Cold and Warm Load Features

When you load a system image, you can specify that a cold or warm load be performed. This is dependent on the setting of the Checkpoint Restart Status field in the $RM AUTOIDS parameter group.

When a cold load is performed, resources defined to the system image are checked, and if automated, are brought into the desired state. The system image is loaded as if this was the first time it was loaded.

When a warm load is performed, resources are placed in the state they were in when this system image was last in use. All manual overrides performed on resources defined to the system image are retained when this system image is loaded.

The Checkpoint Restart Status field displayed on the LOAD Command Parameter Specification panel displays the status as specified in $RM AUTOIDS parameter group.
