HMC

Backing up and restoring the HMC (hardware management console)
Please follow the procedures mentioned below to backup critical console data of HMC.
Importance of backing up HMC :
In case where HMC does not respond or HMC hard disk crashes, the HMC can be brought back to its original state by reinstalling HMC codes though recovery CD and then restoring the critical data which was backed up on either DVD or remote server.
We will follow the steps to backup the HMC critical data on DVD. One DVD media is shipped with HMC. We will make use of this DVD media to take backup. The other process of taking backup on remote server is for reference and can be used.
Backing up critical HMC data
Using the HMC, you can back up all important data, such as the following:
• User-preference files
• User information
• HMC platform-configuration files
• HMC log files
The Backup function saves the HMC data stored on the HMC hard disk to DVD, a remote system mounted to the HMC file system (such as NFS), or a remote site through FTP. Back up the HMC after you have made changes to the HMC or to the information associated with logical partitions.
To back up the HMC, you must be a member of one of the following roles:
• super administrator
• operator
• service representative
To backup the HMC, do the following:
1. In the Navigation area, click the Licensed Internal Code Maintenance icon.
2. In the Contents area, click the HMC Code Update icon.
3. Select Back up Critical Console Data.
4. Select an archive option. You can back up to DVD on the HMC, back up to a remote system mounted to the HMC file system (such as NFS), or a remote site through FTP.
5. Follow the instructions on the panel to back up the data.
Scheduling and reviewing scheduled HMC backups
You can schedule a backup to DVD to occur once, or you can set up a repeating schedule. You must provide the time and date that you want the operation to occur. If the operation is scheduled to repeat, you must select how often you want this backup to run (hourly, daily, weekly, or monthly).
Note: Only the most-recent backup image is stored at any time on the DVD.
To schedule a backup operation, do the following:
1. In the Navigation area, expand the HMC Management folder.
2. In the Navigation area, click the HMC Configuration icon.
3. In the Contents area, click Schedule Operations.
4. From the list, select the HMC you want to back up and click OK.
5. Select Options > New.
6. In the Add a Scheduled Operation window, select Backup Critical Console Data and click OK.
7. In the appropriate fields, enter the time and date that you want this backup to occur.
8. If you want this scheduled operation to repeat, click the Repeat tab and select the intervals at which you want the backup to repeat and press Enter.
9. When you have set the backup time and date, click Save. When the Action Completed window opens, click OK. A description of the operation displays in the Scheduled Operations window.
Restoring critical HMC data
The HMC backup data should be restored only in conjunction with a reinstallation of the HMC. Reinstallation procedure is mentioned below.
Note: For this operation, you must have the backup DVD-RAM media or access to the remote server where the archive was created.
To restore the HMC data, you must be a member of one of the following roles:

Reinstalling the HMC machine code
If the HMC is not responding, you can use the recovery CD to reinstall the HMC interface onto the HMC PC. After you reinstall the HMC machine code, you can restore the backup data that you created to recover your critical console information.
To reinstall the HMC machine code, you must be a member of one of the following roles:
• super administrator

To reinstall the HMC machine code, do the following:

7. After the installation of the second CD completes, select 1 - Install additional software from CD media from the menu displayed to install the information center from the third CD.
8. After the information center installation, select 1 - Restore Critical Console Data from the menu displayed to restore data from a DVD. To restore from a remote server, select 2 - Finish the Installation.
Restoring from DVD
If the critical console data has been archived on a DVD-RAM, do the following:

2. Insert the DVD-RAM containing the archived console data. On first boot of the newly installed HMC, the data automatically restores.
Restoring from a remote server
If the critical console data has been archived remotely, do the following:
1. Manually reconfigure network settings to enable access to the remote server after the HMC is newly installed.
2. In the Navigation area, click the Licensed Internal Code Maintenance icon.
3. In the Contents area, click the HMC Code Update icon.
4. Select Restore Remote Console Data.
5. Select the type of remote restore.
6. Follow the directions on the panel to restore the critical console data. The data automatically restores from the remote server when the system is rebooted.

Logging in to the HMC
After power-on, the HMC login window prompts for the user ID and the password. The HMC is supplied with a predefined user ID hscroot and the default password abc123. Both the user ID and password are case sensitive and must be typed exactly as shown. After the successful login, the HMC graphical user interface opens.
Shutting down, rebooting, and logging off the HMC
This task allows you to shut down, reboot, and log off the HMC interface.
If an operating system is open and running on a partition, and you decide to shut down, reboot, or log off the HMC interface, the operating system continues to run without interruption.
To log off the HMC interface, do the following:
1. In the main menu, click Console > Exit. At this point, you can select to save the state of the console for the next session by selecting the check box next to the option.

If I have two redundant HMC, managing same Managed systems, how can I backup user configuration data of one HMC and restore it on other?

I want only user data. Nothing else...
