v No: Continue with the next step.
v Yes: Go to step 24 (See page 127).
23. Go to the service information for the specific disk unit listed below and perform the action indicated.
Then return here and answer the question below the listed disk units.
v 9337 disk unit: Go to the Starting Problem Analysis section of the 9337 Service Information.
v 2105 disk units: Use SRC 3002 in (2105) Disk Unit Reference Codes and exchange the FRUs
shown one at a time.
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.
24. Exchange the IOA or MSIOP (see Remove and replace procedures).
If exchanging the IOA or MSIOP did not correct the problem, use the original SRC and exchange the
failing items, starting with the highest probable cause of failure. If the failing item list contains FI
codes, see "Failing items" on page 249 to help determine parts and locations.
This ends the procedure.
25. Use Hardware Service Manager to display logical resources connected to the MSIOP (see Hardware
Service Manager in the iSeries
26. Are all the disk devices that are attached to the MSIOP failing?
v Yes: Is there more than one controller attached to the MSIOP?
– Yes: Go to step 24 (See page 127).
– No: Go to step 23 (See page 127).
v No: Continue with the next step.
27. Are all disk units attached to one controller missing?
v Yes: Use the device documentation to correct the problem. Exchange the disk unit controller.
This ends the procedure.
v No: Go to step 23 (See page 127).
0004: Some disk units are unprotected but configured into a mirrored ASP. These units were originally
DPY protected but protection was disabled.
Perform the following:
1. Select DST using Function 21 (see Control Panel Functions in the iSeries
information).
2. Select Work with disk units and take the actions to protect the system.
If you do not know what actions to take, select Manual mode and perform an IPL to DST (see
Performing an IPL to DST in the iSeries
When the Disk configuration error report appears, the recovery actions are listed in the Help text for
the error message "Unprotected disk units in a mirrored ASP".
This ends the procedure.
0005: A disk unit using parity protection is operating in exposed mode.
1. Select Manual mode and perform an IPL to DST (see Performing an IPL to DST in the iSeries
