e. If you have a system with only one disk unit, a message may appear 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. Go to step 15 (See page 550).
f. Otherwise, go to step 16 (See page 550).
15. 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. Select Work with disk configuration—>Work with
ASP configuration—>Delete ASP data.
b. Enter the Delete option for the ASP that you recorded in step 3 (See page 546).
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 new 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).
16. The ASP to which the failing disk unit was assigned was erased. 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 to 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.
17. The remaining steps of this procedure require a dedicated system.
Have the customer do a normal power-off procedure of the system.
18. Perform an IPL to DST. See Performing an IPL to DST in the iSeries Service Functions
information.
Is the IPL or Install the System display shown, or is DST available?
v No: Go to step 2 (See page 546).
v Yes: Select Use dedicated service tools (DST) on the display or use a function key. You need
the customer password to get to the Use Dedicated Service Tools (DST) display. Continue with the
next step.
19. Perform the following:
a. From the Use Dedicated Service Tools (DST) display, select Work with disk units—>Work with
disk configuration—>Display disk configuration—>Display disk configuration status.
b. Record the ASP, unit, serial number, type, and resource name of the disk unit.
c. On the Display Disk Configuration Status display, ensure the following:
v The disk unit is not the load-source disk unit (disk unit 1).
v No disk units are missing from the configuration.
Note: An asterisk (*) next to the unit number indicates a missing unit.
v The status field of the disk unit to be removed shows Configured.
Are all these conditions true?
v Yes: Continue with the next step.
v No: You cannot use the Remove Units from Configuration function. Go to step 2 (See page 546).
