a. Remove the new disk unit from the location you found in step 17 (See page 555). Be very careful
with the disk unit. It contains the disk unit data.
b. Install the new disk unit into the location that contained the failing disk unit. (You removed the
failing disk unit in step 22 (See page 555).)
24. Install the disk unit you removed in step 18 (See page 555).
25. Were any pages unreadable during the copy operation (see step 21 (See page 555))?
v No: The system is ready for the next IPL.
This ends the procedure.
v Yes: Some objects may be damaged. The customer may have to load the damaged objects again.
Have the customer see the Backup and Recovery information.
This ends the procedure.
26. Are there multiple failing disk units under the same IOA?
v No: Continue with the next step.
v Yes: Perform the following:
a. Power off the system.
b. Exchange the storage IOA (see "Remove and replace procedures" on page 2). If you do not
know the part number, see "Type, model, and part number list" on page 520.
c. Go to step 1 (See page 552).
27. Because the disk data was not recoverable, clear the auxiliary storage pool (ASP) to which the disk
unit is assigned by doing the following:
a. Return to the Work with Disk Units display and select Work with disk configuration—>Work
with ASP configuration—>Delete ASP data.
b. Enter Delete for the ASP that you recorded in step 3 (See page 552).
c. Confirm the Delete ASP Data.
d. Return to the Work with Disk Units display and select Work with disk unit recovery—>Replace
configured unit.
e. On the Select Configured Unit to Replace display, select the configured disk unit to exchange.
f. On the Select Replacement Unit display, select the replacement disk unit.
g. Press Enter to confirm the replace operation (this operation takes 10 to 15 minutes to complete).
Attention: The auxiliary storage pool to which the disk unit is assigned was erased. The
customer must restore the data to the auxiliary storage pool (have the customer see the Backup
and Recovery information).
28. 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.
Dedicated service tools (DST) procedures: For use by authorized service providers.
