SIIOADP

Note: In the following procedures, the term RIO adapter refers to either a RIO adapter or an HSL I/O bridge, depending on the server to which it applies.

1. Is a location for this FRU given in the serviceable event view?
   • Yes: Use that location and Table 6 to find and replace the failing part. This ends the procedure.
   • No: Continue with the next step. Note: In most circumstances, the SRC logged by the system firmware calls out a FRU list. In very few circumstances (as in the following examples), the failure requires immediate system termination.

     Example: Symptoms

     1  B7006981  RIO/HSL/12X (bridge) bus adapter failure SRC
     2  XXXXXX62  SRC Format 62
     3  00010002  Component ID field must be an exact match
     4  14993203  Code Model and PRC must be an exact match
     5  FRUCALLO  Decode this when the SRC is 6906 or 6907
     6  FRUCALLO  Decode this when the SRC is 6981
     7  00000000

     Example: SRC 6981

     1 B7006981
     2 00000062
     3 00010002
     4 14993203
     6 00044000
     7 00000000

     When immediate termination occurs, the SRC does not provide a FRU callout. The following steps describe how to determine the FRU callout.
2. Isolate the RIO adapter FRU indicated by the data in word 5 (when the SRC is 6906 or 6907) or word 6 (when the SRC is 6981) of the SRC by completing the following steps:

   Note: Replace only the FRU with the RIO/HSL adapter FRU.

   1. Use the following example as a guide to locate and record the following binary values from word 5 or word 6 of the SRC:
      • RIO hub ID
      • RIO port pair ID
      • RIO loop position

      Example: Decoding FRU Callout 00044000

      Figure 1. Decoding FRU Callout 00044000

      
   2. Convert the binary values for the RIO hub ID, the RIO port pair ID, and the RIO loop position to decimal. Record these values for later use.
3. Each RIO hub controls two RIO loops, specified as the first and second loop. Use the following list to determine and record which of these two RIO loops is indicated in word 6 of the SRC:
   • When the binary value of the RIO port pair ID is 0000, the SRC indicates the first RIO loop
   • When the binary value of the RIO port pair ID is 0001, the SRC indicates the second RIO loop
4. To isolate the failing RIO adapter, you will walk the cabling for the specified RIO loop from the leading port to the trailing port. To determine the RIO loop number and RIO port location code for the leading port, perform the following steps:
   1. Make sure you have the following values at hand, then continue with the next step.
      • The decimal value for the RIO hub ID
      • The RIO loop indicated by the RIO port pair ID
   2. Compare the values from the previous step to the location tables for your server below. Record the values for the RIO loop number and the RIO port location code. Then continue with the next step.

5. Isolate the failing RIO adapter by walking the cabling for the specified RIO loop from the leading port to the trailing port. Complete the following steps:
   1. Begin walking the cabling by starting at the RIO loop number and RIO port location code that you recorded in step 4.b.
   2. Starting with 0 (zero) for the first RIO adapter on the loop, follow the loop cabling and count each RIO adapter in the order it is cabled. For example, the first RIO adapter is 0, the next is 1, the next is 2, and so on.
   3. Continue this process until you count up to the decimal value of the RIO loop position. The RIO adapter that corresponds to the value of the RIO loop position is the failing RIO adapter.
   Note: Concurrent maintenance requires that you make a change to the previous procedure for counting the RIO adapters on the loop. If concurrent maintenance was performed to attach one or more additional RIO adapters to this loop and the server has not performed an IPL after the adapters were added, exclude the added RIO adapters as you make the initial count. If the RIO loop position exceeds the number of RIO adapters, continue by counting the added RIO adapters in the order they were added to the loop.
6. Replace the failing RIO adapter. To determine the FRU part number and the FRU location, use the following table to find and replace the failing part. This ends the procedure.
