Recovery: Perform one of the following tasks:

If the load source has been replaced inadvertently, return the original and restart the server.
If the load source is for the primary partition, recover the logical partition configuration data.
If the specified load source is for a secondary partition, accept the disk as a load source for that secondary partition.
If the specified disk unit is not configured, clear the nonconfigured load source to use the new disk unit in the server.
If a load source disk unit has been moved from a server that has logical partitions, but the current server should not have logical partitions, clear all partition configuration data. This will delete all secondary partitions.
If the load source came from a partitioned server and was inadvertently used to perform a partition IPL, do not take any action. The initialize disk process during installation clears existing configuration data.

The logical partition will not continue its IPL past DST until the problem is corrected with one of the above actions.
