i5/OS: Copying partition configuration data between IPL sources

Your server may experience a disk read error of logical partition configuration data if you restart from the A or B IPL source, but not both.

You can copy the data from the functioning source to the faulty source with this procedure.

You should only attempt this when you are certain that the logical partition restarts normally when using the other IPL source.

Perform this procedure from a Dedicated Service Tools (DST) display:

If you are doing this on the primary partition, power off all secondary partitions. Otherwise, continue to the next step.
Restart your server in manual mode with the other IPL source (for instance, source A if source B fails).
From DST, select option 11 (Work with system partitions).
Ensure that the configuration information contained on this IPL source is correct. Verify this by following the steps in Managing logical partitions for displaying the logical partition's status. A correct configuration would show your most recent configuration of logical partitions. If it is correct, continue to the next step. If the configuration is not correct, do not continue. Consult a service representative.
Press the F3 key to return to the Work with System Partitions menu.
Select option 4 (Recover configuration data).
Select option 6 (Copy configuration data to other side).
Confirm your choice by pressing the F10 key.
Restart the logical partition using the other IPL source (source B, if source A had the correct configuration data you just copied from).
If you continue to have problems, contact a service representative.
