Method and apparatus for recovering logical partition configuration data
First Claim
1. A method in a data processing system for recovering an image of partition configuration information data for a set of partitions having at least one affinity partition, the method comprising:
- detecting damage to an image of partition configuration data;
comparing current partition data with a backup partition data; and
performing a merger of the current partition configuration data with the backup logical partition data if a conflict is present between the current partition configuration data and the backup partition data, wherein merger is performed in a manner avoiding stopping an operation on a running partition in the set of partitions.

Abstract
The present invention provides a method, apparatus, and computer instructions for recovering an image of partition configuration information data for a set of partitions having at least one affinity partition in a logical partition data processing system. (Damage to an image of partition configuration data is detected. Current partition data is compared with a backup partition data. A merger of the current partition configuration data is made with the backup logical partition data if a conflict is present between the current partition configuration data and the backup partition data. The merger is performed in a manner avoiding stopping an operation on a running partition in the set of partitions.
