Recovering logical partition configuration data

 

You can use this option to recover logical partition configuration data if one of your secondary partitions is running the i5/OS^® operating system. This procedure is part of a full server recovery.

The following information applies only to primary partitions.

After reinstalling the Licensed Internal Code on the primary partition, you may need to use DST to recover the logical partition configuration data. Complete the following steps to recover logical partition configuration data:

1. Before changing your disk configuration or recovering your user ASPs, select option 11 (Work with system partitions).

2. Select option 4 (Recover configuration data).

3. Select option 1 (Recover primary partition configuration data). The server locates a non-configured disk unit that contains the most recent configuration data for your server. If the message No units found with more current configuration data displays instead of a list of resources, then no unassigned disk units contain any appropriate configuration information. Consult a service representative for assistance.

4. Select an appropriate configuration to recover.

5. Confirm your selection by pressing Enter.

6. The server copies the new configuration data to the primary partition's load source and automatically restarts the primary partition.

7. When you next perform an initial program load (IPL) for the secondary partitions, the server updates their logical partition configuration data.

8. Once the primary partition completes its IPL, continue with any further recovery steps as outlined in the Recovery section of Backup and Recovery.
