Activate software configuration changes only

The following procedure describes how to change the software configuration for one or more systems in a sysplex.

1. Select one or more systems from the Active Sysplex Member List (see Figure 99) and the Activate software configuration only action from the context menu (or action code  o ). The Activate Software Configuration Only dialog is displayed.

   *----------------------------------------------------------------------------*

   All systems you have selected are shown together with the associated processor IDs.

   Empty Processor ID: 

   If the Processor ID field is empty, prompt for the processor IDs and select the actual one.

   Empty Configuration or EDT ID: 

   If the Config. ID and the EDT ID fields are empty, it is an indication that the ID of the currently active configuration is not defined in the IODF to be activated. Prompt for the new ID. Updating the processor ID, the Config. ID or the EDT ID fields might be required if your IODF to be activated contains IDs different from those displayed as default IDs.

2. On the Activate Software Configuration Only panel, update the fields of one or more systems. It is recommended that you first test an activation before you actually dynamically activate a configuration.
3. If the hardware token matches, the Valid. HW Ch. option is set to 'Yes'. It is recommended to validate hardware changes when performing a software change. This is required when the configuration change contains coupling facility control units or devices.
4. After pressing the Enter key, the Active Sysplex Member List is displayed again, but now the Active Status column shows the status In progress. If you refresh the list occasionally, you can see that one system after the other completes the activation request. This is indicated by the status Messages.
5. Select a system and the View messages action from the context menu (or action code  m ). The messages returned from that system as the result of the activation request are displayed.

6. If you do not need the messages any longer, you can delete them by using the option Delete messages (or action code  d ).

If dynamic activation fails

If the activation is rejected, HCD displays a panel that lists the messages and reasons for a failure.

To get more information you also use the View configuration status option (or action code  v ). This option provides you the same information as when entering the command D IOS,CONFIG(ALL) at the system console.

HCD offers you two possibilities after an activation failed:

• Select Resume activation of target configuration (or action code  t ) to force the activation of the system.
• Select Reset source configuration (or action code  r ) to reset the original configuration.
