Failing Item Code
Description/Action If only a type number is listed, go to the “Type, Model, and Part
Number list” on page 885 to determine the part number.
FI01105 FI01105 indicates that the addressed storage device is the failing item.
Perform the following:
1. Is the device location information available in the Service Action Log?
No Yes
↓ Exchange the failing item. See “Recovery Procedures” on page 893.
Note: If the failing item is in a migration tower, go to recovery procedures in
the Migrated Expansion Tower Problem Analysis, Repair and Parts.
This ends the procedure.
2. Find the IOP address and the device address (see “SRC Address Formats” on page 936).
3. To determine the location of the I/O processor card, see “Locations and Addresses” on
page 705 and find the diagram of the system unit or the expansion unit. Then, find:
v The IOP card location identified by the direct select address.
v The addressed storage device location identified by the device address.
4. Exchange the failing device. Use the device type to determine the part.
FI01106 FI01106 indicates that a storage device other than the addressed storage device is the failing
item.
See FI01105 to find the addressed device. The failing item could be any device with the
same IOP address and I/O (SCSI) bus number but with a different device unit number.
If the reference code that called out this FI does not have a problem analysis procedure,
perform “SDIOP-PIP16” on page 407 to isolate the possible failing device.
FI01107 FI01107 indicates that any storage device attached to the I/O (SCSI) bus of this IOP may be
the failing item.
Perform the following:
1. Find the IOP address (see “SRC Address Formats” on page 936).
2. To determine the location of the I/O processor card, see “Locations and Addresses” on
page 705.
The unit reference code indicates the I/O (SCSI) bus that has the problem:
v URC 3020, 3100 —I/O Bus 0
v URC 3021, 3101 —I/O Bus 1
v URC 3022, 3102 —I/O Bus 2
v Any Other URC—Any I/O bus on the I/O card
3. See “Locations and Addresses” on page 705 and find the diagram of the system unit or
the expansion unit and find:
v The IOP card location identified by the direct select address.
v All the storage devices on the same I/O (SCSI) bus.
Note: The I/O (SCSI) bus number is the first character of the device unit address.
4. Exchange the failing device. Use the device type to determine the part:
If the reference code that called out this FI does not have a problem analysis procedure,
perform “SDIOP-PIP16” on page 407 to isolate the possible failing device.
FI01108 FI01108 indicates that the I/O (SCSI) bus or power cable is the failing item.
See FI01140 and FI01141.
FI01109 A backplane or a connection to the backplane may be failing.
See the symbolic FRU “BACKPLN” on page 504.
