MAP4090 Section-1

Procedure

  1. Did the serviceable event view provide the location(s) for the failing FRU(s)?
    • Yes, use those locations to exchange the given FRUs one at a time until the problem is resolved. This ends the procedure.
    • No, contact your next level of support before you continue with the next step. This procedure from the eServer service Information Center assumes knowledge of the HMC options that the storage facility service representative is not trained with.
  2. Go to MAP4091 DSA translation to determine the Direct Select Address (DSA) in decimal value and then return here and go to the next step.
  3. Record the Cc value from the DSA.

    Is the Cc value greater than 00?

    • Yes, go to the next step.
    • No, the multi-adapter bridge number and the multi-adapter function number have not been identified, so the card slot cannot be identified using the DSA. Look in the HMC partition resources for non-reporting or non-operational hardware. That will indicate which cards in which positions need to be replaced. If replacing the PCI card does not fix the problem, replace the backplane that the card is plugged into. This ends the procedure.
  4. Is the right-most character (the c character) F?

    • No, go to the next step.
    • Yes, only the multi-adapter bridge number has been identified. Record the multi-adapter bridge number (left-most character of Cc) for later use. Since the card slot cannot be identified with the DSA, see . Consider all of the card slots that are controlled by the multi-adapter bridge to be FRUs. This ends the procedure.
  5. Refer to MAP4092 Card positions and use the BBBB and Cc values that you recorded to identify the card position. Then return to the procedure that sent you here. This ends the procedure.
