Recovery display. This option assembles the system configuration
information on disk unit 1 in the system unit.

destroys all system data.

stating that your request to recover the configuration was not successful.
The recover configuration function cannot be performed on a system with
only one disk unit.
Continue with the next step of this procedure.
18. The ASP to which the failing disk unit was assigned is cleared. The customer
should do the following:
v If the disk unit you exchanged is in ASP 1, have the customer see the
Backup and Recovery information. You must restore the operating system
(OS/400 Licensed Program) and all customer data.
v If the disk unit is in a user ASP (ASP 2 through ASP 16), data in the ASP is
lost. See the Backup and Recovery information.
This ends the procedure.

(see “Restoring Licensed Internal Code” in the iSeries Service Functions
information). This information shows you how to perform an IPL and restore
the Licensed Internal Code.

damaged objects again (see the Backup and Recovery information).
This ends the procedure.
20. Is the failing unit missing from the configuration?

21. Find another disk unit on the system, other than the load-source disk unit.
22. Perform the following to install a new disk unit on the system:
a. Power off the system.
b. Slide the disk unit you found in step 21 of this procedure out of the
system (see “Chapter 4. Removal and Installation Procedures” on
page 617).

actions to the failing disk unit are complete.
d. Install the new disk unit.
