The Direct Select Address (DSA) may be coded in word 7 of the reference code.

About this task

This is either a PCI system bus number or a RIO loop number, depending on the type of error. With the information obtained here, and the information in either the card position table (for PCI bus numbers) or the information in the loop-number-to-NIC-port table (for RIO loop numbers), you should be able to isolate a failing PCI bus or RIO loop. Follow the instructions below to translate the DSA:

Procedure

  1. Break down the DSA into the bus number, multi-adapter bridge number, and multi-adapter bridge function number as shown in the tables that follow. The DSA is of the form BBBB Ccxx, and breaks down into the following parts:
    • BBBB = bus number
    • C = multi-adapter bridge number
    • c = multi-adapter bridge function number
    • xx = not used
  2. Is the bus number less than 0684?
    • Yes, the bus number is a PCI bus number. Refer to Table 1 to convert the number to decimal, and then continue with the next step.
    • No, the bus number is a RIO loop number. Refer to Table 2 to convert the number to decimal, and then continue with the next step.
  3. To determine if the bus is located in the system unit or expansion unit, view the managed system's properties on the HMC.
  4. Perform one of the following:
    • Refer to Table 3 and Table 4 to search for the bus number, the multi-adapter bridge number, and the multi-adapter bridge function number that matches the system unit or I/O tower type where the bus is located. This ends the procedure.
    • Refer to Converting the loop number to NIC port location labels to determine the starting ports for the RIO loop with the failed link. This ends the procedure.
