FCPORT

The Fibre Channel IOA port might be the failing item. Perform the following:

  1. If the system has logical partitions, perform this procedure from the logical partition that reported the problem. To determine if the system has logical partitions, go to Determining if the system has logical partitions before continuing with this procedure.
  2. Access SST/DST by doing one of the following:
    1. If you can enter a command at the console, access system service tools (SST). See "System Service Tools (SST)" in the service guide for the server.
    2. If you cannot enter a command at the console, perform an IPL to DST. See Performing an IPL to DST, this topic is available in the service guide for the server.
    3. If you cannot perform a type A or B IPL, perform a type D IPL from removable media.
  3. Is a Fibre Channel IOA URC (last four digits of SRC) 3120 or 3121 logged or been logged within 5 minutes of the SRC that sent you to this symbolic FRU?
    • Yes: Continue with the next step.
    • No: The Fibre Channel IOA port has not failed. See the next FRU in the FRU list. This ends the procedure.
  4. Did you perform a D IPL to get to DST?
    • Yes: Continue with the next step.
    • No: Continue with step 6. This ends the procedure.
  5. Use the Product Activity Log to get the resource name for the 3120 or 3121 SRC. See Using the Product Activity Log, this topic is available in the service documentation for the server. Using the resource name, perform the following steps in DST/SST:
    1. Click Start a service tool > Hardware service manager > System bus resources.
    2. If the resource is an I/O processor, use "Resources associated with IOP" to find and display detail for the Fibre Channel I/O adapter. If the resource is a Fibre Channel I/O adapter, use "Resources associated with the IOP for all type 2847 I/O processors" to find and display the Fibre Channel I/O adapter.
    3. Select the Display additional port information function key on the Auxiliary Storage Hardware Resource Detail display.

    Does the Port status field indicate that the port is active?

    Note: If 3120 is logged, check to see if port 0 is active. If 3121 is logged, check to see if port 1 is active.

    • Yes: Continue with step 7.
    • No: Continue with step 9.
  6. Use the Service Action Log to get the resource name for the 3120 SRC, see Using the Service Action Log, this topic is available in the service guide for the system unit. Using the resource name, perform the following steps in DST/SST:
    1. Click Start a service tool > Hardware service manager > Locate resource by resource name.
    2. Enter the resource name.
    3. Click the Display detail option for the Fibre Channel I/O adapter on the Logical Hardware Resources display.
    4. Click the Display additional port information function key on the Auxiliary Storage Hardware Resource Detail display.

      Does the Port status field indicate that the port is "active"?
      Note: If 3120 is logged, check to see if port 0 is active. If 3121 is logged, check to see if port 1 is active.

      • Yes: Continue with the next step.
      • No: Go to step 9.

  7. The port is now active. Has a 1750/2105/2107 3002 SRC occurred around the time the problem was first reported?
    • Yes: Continue with the next step.
    • No: No further service actions are required. This ends the procedure.
  8. A 1750/2105/2107 3002 has occurred, and the link has gone from not active to active. The Fibre Channel IOA port is functional. Choose from the following options:
    • If the disk units that reported the 1750/2105/2107 3002 SRC are usable, then no further service actions are required. This ends the procedure.
    • If the disk units that reported the 1750/2105/2107 3002 SRC are not usable, then go back to the 1750/2105/2107 3002 FRU list and work with a FRU other than FCPORT. This ends the procedure.
  9. Clean the Fibre Channel IOA wrap plug using the cleaning kit. Follow the instructions in the Fiber Optic Cleaning Procedures, order number SY27-2604. If the wrap plug has been lost, order and clean a new one. See Managing PCI Adapters, order number SA76-0107 for the part number.
  10. Perform the following steps:
    1. Install the wrap plug on the Fibre Channel IOA.
    2. After the wrap plug has been installed, wait 5 seconds.
    3. Choose from the following options:
      • If you are on the Additional Port Information display, use the Refresh function key.
      • If you are not already on the Additional Port Information display, use the instructions from step 6 to check if the port has become active.
    Is the port status now "active"?
    • Yes: Continue with the next step.
    • No: Replace the Fibre Channel IOA. See symbolic FRU FCIOA for further instructions and the FRU part number. This ends the procedure.
  11. Ask the customer whether the Fibre Channel IOA will attach devices now or whether the Fibre Channel IOA is to be used at a later time. Is the Fibre Channel IOA intended to attach devices at this time?
    • No: The wrap plug remain installed on the Fibre Channel IOA when it is not in use. No further service actions are required. This ends the procedure.
    • Yes: Perform the following steps:
      1. Unplug the wrap plug from the Fibre Channel IOA and wait until the port status becomes "Not active" using the Refresh function key on the Additional Port Information display. The failure has been isolated to the first link, which includes any of the cables or junctions between the Fibre Channel IOA port and the first Fibre Channel hub, switch, gateway, or device.
      2. Use existing Fibre Channel service procedures to continue diagnosis of this first link until the port status becomes active, or contact your next level of support. This ends the procedure.
