Identifies the prerequisites needed and the tasks that must be performed when you replace a Hardware Management Console (HMC).
If you are replacing an HMC that is set up as a DHCP server, you must first reinstall the HMC code base by using one of the following:
- The recovery media that was provided with your HMC
- The recovery media that you last used to upgrade your HMC
You must also reinstall your customized HMC configuration data by using backup media.
Procedures for replacing an HMC differ, depending on which HMC version you have installed. To determine your HMC version, see Determining your HMC machine code version and release and then return here.
These instructions assume that you have created a backup of your HMC configuration data from the HMC being replaced. For more information about backing up important HMC data, see Backing up critical HMC data.
- For HMC V4.5 or earlier
- Insert the HMC recovery media, then power on or reboot the HMC. The HMC powers on and loads from the media.
- Press F8 to select Install/Recovery.
- Press F1 to continue. After the installation is complete, the HMC prompts you to insert the backup media.
- Insert the backup media. When you are finished, the HMC is restored to the state that it was in at the time that the backup was created.
- After the HMC interface has been restored, verify that your HMC DHCP private network is configured correctly. For more information, see Verifying that your HMC DHCP private network is configured correctly.
- For HMC V5.0 or later
- Insert the HMC recovery media, then power on or reboot the HMC. The HMC powers on from the media and displays the Backup/Upgrade/Restore/Install panel.
- Select Install and click Next. Wait for the installation to complete.
- Select 1 - Install additional software from media from the menu displayed to install the second HMC recovery media.
- Remove the recovery media and insert the second media.
- Press Enter to start the installation of the second recovery media.
- After the installation is complete, remove the second recovery media, insert the backup media, and select 1 - Restore Critical Console Data from the menu to restore data from the backup media. When you are finished, the HMC is restored to the state that it was in at the time that the backup was created.
- After the HMC interface has been restored, verify that your HMC DHCP private network is configured correctly. For more information, see Verifying that your HMC DHCP private network is configured correctly.
