Is word 5 of the reference code zero (0000 0000)?

• Yes: Perform SIIOADP.
• No: Perform PIOCARD.

This ends the procedure.

PIOCARD

The failing component is the adapter in the location specified by the Direct Select Address (DSA) in the reference code. When possible, the diagnostic code will determine the FRU location for the serviceable event view.

1. Are you working from the serviceable event view and a card location is listed with this FRU?
   • Yes: The error is located at the listed card location. Go to step 5.
   • No: Perform the following:
     1. Record the DSA, which is word 7 of the reference code.
     2. Locate the card specified in the DSA by going to MABIP53. Return here after locating the FRU and continue with the next step.
2. Did you identify a single FRU location by using MABIP53?
   • Yes: This is the location of the failing item. Go to step 5.
   • No: Continue with the next step.
3. Perform the following, referring to the remove and replace procedures for each FRU location you determined (you can find links to the locations information, and from there to the remove and replace procedures, in the table at the end of this procedure):
   1. Remove all of the adapter and/or IOP cards in the locations that are identified in the given range of card slots. Do not remove any FRUs with embedded adapters, only FRUs in PCI card slots.
   2. Replace each card one at a time.
      Note:
      For i5/OS^(R) adapters controlled by IOPs, replace the IOP before any of the adapters.
      Power on the unit after you replace each card until either the problem reappears or you have replaced each card.
   3. Did the problem reappear?
      • Yes: The last card that you replaced before the problem appeared again is the failing item. This ends the procedure.
      • No: Continue with the next step.
4. Did you identify a FRU with embedded adapters when performing MABIP53?
   • Yes: The problem is in the FRU with the embedded adapter. Continue with the next step and exchange that FRU.This ends the procedure.
   • No: The problem may be intermittent. Contact your next level of support. This ends the procedure.
5. Use the table below to locate and replace the failing item. This ends the procedure.

   System model, expansion unit, or machine type	Name of FRU to exchange	FRU location
   9117-MMA and 9406-MMA	PCI adapter, if you have detected a failing PCI adapter in a PCI slot of a system unit drawer, replace the PCI adapter that is in the failing slot.	Un-P1-Cx

   7311-D11	PCI adapter, if you have detected a failing PCI adapter in a PCI slot of an I/O expansion drawer, replace the PCI adapter that is in the failing slot.	Un-P1-Cx
   7311-D20	PCI adapter, if you have detected a failing PCI adapter in a PCI slot of an I/O expansion drawer, replace the PCI adapter that is in the failing slot.	Un-Px-Cy

SIIOADP

1. Is a location for this FRU given in the serviceable event view?
   • Yes: Use that location and replace the failing part. Refer to Locating FRUs.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 (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 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

      
   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, do the following:
   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 table (Table 37) and graphic below. Record the values for the RIO loop number and the RIO port location code. Then continue with the next step.
      • Locating FRUs

      Table 37. Model MMA SIIOADP RIO loop location information

      System Unit	Hub (decimal)	Hub loop	Loop number (hex / dec)	Location code for leading port of the loop

      0	1	First	0781/1921	-P1-C8-T2

      3	26	First	079A/1946	-P1-C9-T2

      
5. Isolate the failing RIO adapter by walking the cabling for the specified RIO loop from the leading port to the trailing port. Do the following:
   1. Begin walking the cabling by starting at the RIO loop number and RIO port location code that you recorded in step 4b.
   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 been IPL'ed after the adapters were added, then 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. Exchange the failing RIO adapter. Refer to Locating FRUs. This ends the procedure.
