Accepting a disk unit as load source for a logical partition
If you have recently moved or added disk units either within the server or from another server, they may still contain configuration data. If you do not want to use one of them as the load source, you need to clear the configuration data before proceeding.
When configuration data on the load source of a logical partition is different from what the server expects, an error displays in the product activity log (PAL). A reference code of B600 5311 occurs against the load source disk unit.
Otherwise, if you do want to use one of the new disk units as your new load source on the logical partition, follow these steps from the dedicated service tools (DST) menu:
- At the DST menu, select option 11 (Work with system partitions).
- Select option 4 (Recover configuration data).
- Select option 5 (Accept load source disk unit).
- Confirm that you really do want to use the disk as a load source in the logical partition by pressing the F10 key. The server replaces the configuration data on the load source disk unit with the current configuration data.
- The logical partition may now continue its IPL with the new load source disk unit.
