Resolving LPAR configuration error

 

If a logical partition configuration error was detected when you turned on the system after the new I/O adapter installation, you can perform these steps.

Partition configuration errors may exist at this point in the new I/O adapter installation process.

All new buses will be owned with a shared status by the primary partition. If it was determined in step 9 in the task of Documenting and preparing the server that secondary partition load-source disk units would be relocated, LPAR configuration errors will occur.

Verify that the configuration error detail identifies a disk unit that is the load source for a secondary partition that owned the converted expansion unit.

  1. Access dedicated service tools (DST) and sign on.

  2. From the DST main menu, select option 11 (Work with system partitions) and press Enter.

  3. Select option 4 (Recovery configuration data) and press Enter.

  4. Select option 3 (Clear non-configured disk unit configuration data) and press Enter. This display should show the number of load-source disk units determined in step 9 in the task of Documenting and preparing the server. If the load-source disk units do not all report, clear the ones that do report, wait a few minutes, and then submit the request again. If the number of disk units expected does not show up after 10 minutes, you might have hardware or software problems. Call IBM® software support for assistance.

  5. Type option 1 (Select unit to clear) next to the displayed disk unit or units and press Enter.

  6. Press Enter again to confirm.

  7. Return to the DST main menu.
