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:
- Open the CA Server Automation user interface from the Start menu. Click Administration, Configuration.
The Configuration page appears.
- 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.
- Click (Configure Managed/VIO Servers) that is associated with the HMC Server.
The IBM PowerVM dialog with Managed/VIO Servers appears.
- Click (Switch the preferred HMC) under the Actions row and confirm.
The redundant HMC is set as the preferred HMC.
