TOPORT

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

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, then the following conditions have occurred:

In this case, go to the appropriate System Reference Codes volume and look up SRC B700 6985 and work from the full FRU list provided there. The system reference codes are listed in the following documents:

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

To find the failing RIO/HSL/12X adapter, do the following:

  1. Record the bus number (BBBB) in word 7 of the reference code (see Breaking down a RIO/HSL/12X or PCI bus reference code).
  2. Use one of the following procedures to find the failing RIO/HSL/12X adapter:

Finding the failing RIO/HSL adapter using i5/OS(R)

  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 RIO/HSL/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, then 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. 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 RIO/HSL/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, use the following table to determine the failing FRU part number. This ends the procedure.
    CCIN or FFC Type and model Part number Description Location code
    2886 5094, 5096 39J0669 RIO/HSL optical bus adapter Un-CB1-C10
    2887 5094, 5096 39J0527 RIO/HSL2 adapter Un-CB1-C10
    28E7 5094, 5096 39J0523 RIO/HSL2 adapter Un-CB1-C10
    28FF 5790 03N5633 RIO/HSL2 adapter Un-P1-C7
    28E7 0595, 5095 39J0523 RIO/HSL2 adapter Un-P1-C5
    520A 5796 10N8782 Dual-port 12X adapter Un-P1-C7
    1800 9406-MMA 39J0792 RIO/HSL-2 adapter Un-P1-Cx
    1802 9406-MMA 42R6849 GX DUAL-PORT 12X HCA Un-P1-Cx
    This ends the procedure.

Finding the failing RIO/HSL/12X adapter using AIX or Linux

  1. Determine on which RIO/HSL/12X loop the failing adapter is located. Refer to Converting the loop number to NIC port location labels). "Converting the loop number to RIO/HSL/12X port location labels" is available in the service guide for the server.
  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 RIO/HSL/12X adapter in the last I/O unit added is possibly the failing item. Use the following table to determine the part number for the field replaceable unit (FRU):

      CCIN or FFC Type and model Part number Description Location code
      28FF 7311-D11 03N5633 RIO/HSL2 adapter Un-P1-C7
      28E7 7311-D20 39J0523 RIO/HSL2 adapter Un-P1-C5
      520A 7314-G30 10N8782 Dual-port 12X adapter Un-P1-C7
      1800 9117-MMA 39J0792 RIO/HSL-2 adapter Un-P1-Cx
      1802 9117-MMA 42R6849 GX DUAL-PORT 12X HCA Un-P1-Cx

Finding the failing RIO/HSL/12X adapter using the HMC

  1. From the HMC, expand Systems Management then expand Servers. Select the server on which you are working then expand Hardware Information, then click View RIO-12X Topology.
  2. In the Current Topology area, scroll down until you find data for the RIO/HSL/12X loop number with which you are working.
  3. Each line in that RIO/HSL/12X loop represents a RIO/HSL/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):

    CCIN or FFC Type and model Part number Description Location code
    28FF 7311-D11 03N5633 RIO/HSL2 adapter Un-P1-C7
    28E7 7311-D20 39J0523 RIO/HSL2 adapter Un-P1-C5
    520A 7314-G30 10N8782 Dual-port 12X adapter Un-P1-C7
    1800 9117-MMA 39J0792 RIO/HSL-2 adapter Un-P1-Cx
    1802 9117-MMA 42R6849 GX DUAL-PORT 12X HCA Un-P1-Cx
This ends the procedure.
