FRPORT

This procedure locates the start of the failing RIO link.

About this task

The RIO node on one end of the link might be the failing item. If you were sent to this procedure as a result of a B7006985 SRC, and this is the only FRU in the FRU list, the system cannot see any I/O units on a RIO loop and there is at least one cable attached to a port on that loop. In this case, go to (B700) Reference codes and work from the full FRU list provided there.

Note: The other end of the link is given in the symbolic FRU TOPORT.

Procedure

  1. Record the bus number in the first half of word 7 of the reference code. Table 1 shows the reference code format.
    Table 1. Reference code format
    Word number    
    1 2 3 4 5 6 7 8
    TTTTUUUU xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx BBBBxxxx xxxxxxxx
    Key:
    TTTT = Reference code type (B600xxxx or B700xxxx)
    UUUU = Unit reference code
    BBBB = RIO bus number
  2. Find the failing RIO node on the management console:
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the bottom Task area, click Service Utilities > View Hardware Topology.
    3. In the Current Topology area, scroll down until you find data for the RIO loop number you are working with.
    4. Each line in that RIO loop represents a RIO node. Find the first one with a leading port status of failed.
    5. Record the location code of the first failed resource.

What to do next

This ends the procedure.
