DEVBPLN

For use by authorized service providers.
A device backplane may be failing.
Replace the device backplane. Use the device backplane information in the Service Action Log. See
Locations and addresses for the model you are working on for location, part number, and remove and
replace procedure information.

DEVICE

For use by authorized service providers.
The addressed storage device is the failing item. Perform the following.
1. Is the device location information available in the Service Action Log?
v No: Continue with the next step.
v Yes: Exchange the failing item. See Data recovery procedures and general system information.
Note: If the failing item is in a migration tower, go to Chapter 6 in the Migrated Expansion Tower
Problem Analysis, Repair and Parts manual on the V5R1 Supplemental Manuals web site
This ends the procedure.
2. Find the IOP address and the device address. See SRC address formats.
3. To determine the location of the I/O processor card, see Locations and addresses 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.
This ends the procedure.

DEVTERM

For use by authorized service providers.
The device terminating plug may be failing.
Perform the following.
1. Find the IOA type:
a. Find the IOA location information in the Service Action Log if it is available. If the location is not
available, find the address of the IOA. See SRC address formats. Use the address to find the
location. See Locations and addresses list.
If the failing item is in a migration tower, go to the DEVTERM symbolic FRU in Migrated Expansion
Tower Problem Analysis, Repair and Parts manual on the V5R1 Supplemental Manuals web site
.
b. Find the IOA card in the system and read the type number of the card at that location.
2. Use the information in the following list to determine the failing terminating plug:
