Work with the FRU list in the serviceable event view if there is one, otherwise use the FRU list documented here to determine the parts to exchange.

The four rightmost characters of word 4 in the reference code represent the Program Return Code (PRC), which describes the problem detected. The four leftmost digits of word 7 represent the loop number in hexadecimal format. Convert the loop number to decimal format before comparing it to loop numbers shown in serviceable event views and service tools.

To determine the problem, find the PRC in the list below.

Note: The FRU description in the serviceable event view may already contain a message that identifies the problem.

• xxxx 0008 indicates the system serial number is not set. Set the serial number on the system unit. If the problem persists contact your next level of support.
• xxxx 3201 indicates there are clustered systems on multiple HSL/RIO loops. You will need to ensure all clustered systems are on the same HSL/RIO loop.
• xxxx 3217 indicates there is a model 5791, 5792, or 5794 IO drawer on a loop with clustered systems. This is not a supported configuration.

This ends the procedure.
