MABIP02

Use this procedure to determine if the multi-adapter bridge is failing when the symbolic FRU PIOCARD is in the failing item list, with other failing items that have a multi-adapter bridge as a component.

The procedure will start with the failing item list for the SRC that sent you here. It will determine if PIOCARD should be removed from the failing item list that you are working in.

Use the Service Action Log (SAL) to check for other errors under the same multi-adapter bridge. See Using the Service Action Log for details.

  1. Were you able to obtain a location for the PIOCARD FRU from the SAL?
  2. Record the Bus number (BBBB part) of the DSA and the Multi-adapter bridge number of the DSA. The multi-adapter bridge number is the first character of the card identifier part (Cc) in the DSA. See Breaking down a RIO/HSL/12X or PCI bus reference code to find the DSA in the SRC.
  3. Go to MABIP53 to determine the location of the PCI I/O Card in the failing item list. Return here and continue with the next step.
  4. Using the card position table for the frame or I/O unit type that you recorded in MABIP53, determine which of the card positions within the frame or I/O unit are controlled by the same multi-adapter bridge that is controlling the PCI I/O card for which you determined the location in step 3. See Card positions. A card position is controlled by the same multi-adapter bridge if it has the same bus number and multi-adapter bridge number as the PCI I/O Card that you located in step 3. Record the card position and the DSA from the card position table for each card position that is controlled by the same multi-adapter bridge.
  5. Look in the SAL for other failures in the same I/O unit that are located in any of the card positions that either you recorded in step 4 or that are listed in the SAL with the PIOCARD FRU.
  6. Are there any other failures within the same I/O unit that correspond with any of the card positions that you recorded in step 4 or that are listed in the SAL with the PIOCARD FRU?
