v 432x, 660x, 671x Disk Units: Use SRC 3002 in (432x, 660x, 671x, 673x) Disk Unit Reference
Codes and exchange the FRUs shown one at a time.
Did the disk unit service information correct the problem?
v No: Continue with the next step.
v Yes: This ends the procedure.
9. Perform the following:
a. Exchange the IOA. Use the IOP direct select address and the first character of the unit address
from step 2 (See page 134) to find the location. See Locations and addresses.
b. If exchanging the IOA does not correct the problem, exchange the IOP. Use the IOP direct select
address from step 2 (See page 134) to find the location. See Locations and addresses.
c. If exchanging the IOP does not correct the problem, exchange the failing items in the following
FRU list starting with the first item in the list.
1) FI01140
2) BACKPLN
3) FI00580
4) AJDG301
This ends the procedure.
0004: Some disk units are unprotected but configured into a mirrored IASP. These units were originally
DPY protected but protection was disabled.
Direct the customer to take the actions necessary to start protection on these disk units.
This ends the procedure.
0007: Some of the configured disk units have device parity protection disabled when the system
expected device parity protection to be enabled.
1. Select Manual mode and perform an IPL to DST. See Dedicated Service Tools (DST) in the iSeries
Service Functions
2. Correct the problem by doing the following:
a. Select Work with disk units —> Work with disk unit recovery —> Correct device parity
protection mismatch.
b. Follow the on-line instructions.
This ends the procedure.
0008: A disk unit has no more alternate sectors to assign.
1. Determine the failing unit by type, model, serial number or address given in words 4-7. See System
Reference Code (SRC) Information in the iSeries Service Functions
2. See the service information for the specific storage device. Use the disk unit reference code listed
below for service information entry.
432x 102E, 660x 102E, 671x 102E (see System Reference Codes).
This ends the procedure.
0009: The procedure to restore a disk unit from the tape unit did not complete.
Continue with the disk unit exchange recovery procedure. See "Disk Service Support" in Recovery
procedures.
This ends the procedure.
000A: There is a problem with a disk unit subsystem. As a result, there are missing disk units in the
system.
