POWER7 information

TOPORT

The 12X adapter or controller on one end of the link might be the failing item.

If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to find additional location codes, part numbers, or replacement procedures for your system.

If you were sent to this procedure as a result of a B700 6985 SRC, and this is the only FRU in the FRU list, the following conditions have occurred:

  • The system cannot see any I/O expansion units on a 12X loop
  • At least one cable is attached to a port on that loop

In this case, go to Reference codes and look up SRC B700 6985 and work from the full FRU list provided there.

Note: The other end of the link might be given in the symbolic FRU FRPORT.

Complete the following steps to find the failing 12X adapter:

  1. Record the bus number (BBBB) in word 7 of the reference code. See Analyzing a 12X or PCI bus reference code .
  2. Use one of the following procedures to find the failing 12X adapter:

Finding the failing 12X adapter by using IBM i operating system

  1. Sign on to SST or DST if you have not already done so.
  2. Select Start a service tool > Hardware service manager > Logical hardware resources > High-speed link (HSL) resources.
  3. Select Include non-reporting resources then click Display detail for the 12X loop that you want to examine. The loop number is the number from word 7 of the reference code above.
  4. The display that appears shows the port status of the Network Interface Controller (NIC) for the loop that you selected. Record the resource name, type-model, and serial number.
  5. If the status of the "Leading port to next resource" is operational, select Follow Leading Port. Repeat this action until the status changes to failed. Does the resource name ever match the one recorded in the previous step?
    • Yes: You have traveled around the loop and did not find a failed link. This ends the procedure.
    • No: Continue with the next step.
  6. When the status is failed, you have found the from port. Since you are looking for "TOPORT", select Follow Leading Port one more time, which moves to the to port.
  7. Record the following information of this resource:
    1. Resource name, card type and model, and part number
    2. Link status of each port (make sure to note if a port is designated as internal)
  8. Select Cancel to return to the Work with High-speed link (HSL) resources display.
  9. For the loop with the failure, select Resources associated with loop.
  10. For the 12X I/O bridge with the resource name that you recorded, select Associated packaging resources.
  11. Select Display detail and record the location for the first failing resource.
  12. Replace this FRU using the table below to determine the failing FRU part number. This ends the procedure.

Finding the failing 12X adapter by using AIX or Linux

  1. Determine on which 12X loop the failing adapter is located. Refer to Converting the loop number to 12X port location labels .
  2. Identify each unit in the loop by following the cable.
  3. Power down the system and remove all expansion units in the loop that starts and ends at the ports given in the previous step.
  4. Power on the system to partition standby and check for the same SRC that sent you here. Did the SRC reoccur?
    • No: Power down the system and add the next unit in the original loop. Repeat this step.
    • Yes: If there are no expansion units in the loop, replace the controller on the system unit. Otherwise, the 12X adapter in the last I/O unit added is possibly the failing item. Use the table below to determine the part number for the field replaceable unit (FRU). This ends the procedure.

Finding the failing 12X adapter by using the management console

  1. If you are using the Hardware Management Console, perform the following steps:
    1. From the HMC, expand Systems Management > Servers.
    2. Select the server on which you are working, expand Hardware Information, and click View RIO-12X Topology.
    3. In the Current Topology area, scroll down until you find data for the 12X loop number with which you are working.
    If you are using the Systems Director Management Console (SDMC), perform the following steps:
    1. From the SDMC, select the server on the Resources page.
    2. Click Actions > Hardware Information > View Hardware Topology.
    3. Click Actions, and select Hardware Information to view the RIO-12X topology.
    4. Scroll down until you find data for the 12X loop number with which you are working.
  2. Each line in that 12X loop represents a 12X adapter or controller. Find the first one with a "Trailing Port Status" of failed. Replace the failing adapter or controller. Use the following table to determine the part number for the field replaceable unit (FRU).
