Change the Preferred HMC for the Managed Power System

If your Power System uses a dual HMC, you can change the preferred HMC.

Important! Verify that one LPAR AIM manages both the primary and the redundant HMC servers.

Follow these steps:

1. Open the CA Virtual Assurance user interface from the Start menu. Click Administration, Configuration.

   The Configuration page appears.

2. Select IBM PowerVM from the Provisioning section in the left pane.

   The right pane refreshes and displays the managed HMC and IVM Servers, associated Virtual I/O Servers, and the LPAR AIM Servers.

3. Click (Configure Managed/VIO Servers) that is associated with the HMC Server.

   The IBM PowerVM dialog with Managed/VIO Servers appears.

4. Click (Switch the preferred HMC) under the Actions row and confirm.

   The redundant HMC is set as the preferred HMC.
