Exchanging a Disk Unit with Device Parity Protection
1. Does the failing unit have data parity protection that allows service without
possible data loss (see “Determining Storage Protection Status” on page 894)?
Yes No
↓
Customer data may be lost if serviced. Ask your next level of support
for assistance.
This ends the procedure.
2.
Record the disk unit location for later use. If you do not already have the disk
unit location information, use the location information in the Service Action
Log if it is available. If the location is not available, find the address. See “SRC
Address Formats” on page 936. Use the address to find the location. See
“Locations and Addresses” on page 705.
Exchange the failing disk unit (See “Chapter 4. Removal and Installation
Procedures” on page 617 for the model or FC that you are working on and
perform
″
Disk Unit - Concurrent
″
). When finished, continue with the next step
of this procedure.
Note: If the concurrent procedure fails, go to step 5 of this procedure.
3. Perform the following:
a.
Select System Service Tools (SST).
If you cannot get to SST, select dedicated service tool (DST) (see “Accessing
Dedicated Service Tools” in the
iSeries Service Functions ).
Note: Do not IPL the system to get to DST.
b. Select the Work with disk units option on the Service Tools display.
c. Select the Work with disk unit recovery option on the Work with Disk Units
display.
d. Select the Rebuild disk unit data option.
Does the disk unit you just exchanged appear on the display as a unit that can
be rebuilt?
Yes No
↓
It can take up to 5 minutes for the input-output processor (IOP) to
report the device to the system. Keep trying the
Rebuild Disk Unit Data
option until the device is available. If the
″
Rebuild Disk Unit Data
Failed
″
screen continues to appear even after 5 minutes, try a different
disk unit or ask your next level of support for assistance.
4. Perform the following:
a. Select the disk unit on the display that was installed in place of the failing
disk unit.
b. Rebuild the disk unit data. When the new disk unit is rebuilt, the display
shows that the status is complete (this may take 30 minutes or longer).
Note: Once the rebuild has started, it is not necessary to wait to verify the
array rebuild completes successfully.
c.
Return to the procedure that sent you here.
This ends the procedure.
