Upgrading FPD on the Cisco ASR 9000 Series Router

In general terms, field-programmable devices (FPDs) are hardware devices implemented on router cards that support separate software upgrades. A field-programmable gate array (FPGA) is a type of programmable memory device that exists on most hardware components of the router. The term FPD has been introduced to collectively and generically describe any type of programmable hardware device on SIPs and shared port adapters (SPAs), including FPGAs and the read-only memory monitor (ROMMON). Cisco IOS XR software provides the Cisco FPD upgrade feature to manage the upgrade of FPD images on SIPs and SPAs.

This chapter describes the information that you must know to verify image versions and to perform an upgrade for SPA or SIP FPD images when incompatibilities arise.

For complete descriptions of the FPD commands listed in this module, see Related Documents. To locate documentation for other commands that might appear in the course of performing a configuration task, search online in Cisco ASR 9000 Series Aggregation Services Router Commands Master List.

Support for FPD upgrades was introduced.

This module contains the following topics:

Prerequisites for FPD Image Upgrades

Before upgrading the FPD on your router you must install and activate the Cisco ASR 9000 Series Router-fpd.pie. For information about performing this task, see the Upgrading and Managing the Cisco ASR 9000 Series Router module in Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide.

Overview of FPD Image Upgrade Support

An FPD image is used to upgrade the software on an FPD. Whenever a Cisco IOS XR Software image is released that supports SIPs and SPAs, a companion SIP and SPA FPD image is bundled with the Cisco IOS XR software release. Generally, the FPD image is not automatically upgraded. You must manually upgrade the FPD image running on the SPA or SIP when you upgrade the Cisco IOS XR software image.

FPD versions must be compatible with the Cisco IOS XR software that is running on the router; if an incompatibility exists between an FPD version and the Cisco IOS XR software, the device with the FPGA may not operate properly until the incompatibility is resolved. An FPGA incompatibility on a SPA does not necessarily affect the running of the SPA interfaces; an FPD incompatibility on a SIP disables all interfaces for all SPAs in the SIP until the incompatibility is addressed.

Use the show hw-module fpd command to determine if an FPD upgrade is required. A value of ‘Yes’ in the Upg/Dng? (upgrade/downgrade) column indicates that an upgrade or downgrade is required.

The Cisco ASR 9000 Series Router supports upgrades for FPGA devices on its SIPs and SPAs. FPGA and ROMMON software upgrades are part of an FPD image package that corresponds to a Cisco IOS XR software image. SIPs and SPAs support manual upgrades for FPGA devices using the Cisco FPD upgrade feature that is further described in this chapter.

Automatic FPD Upgrade

By default, the FPD image is not automatically upgraded. Generally, you must manually upgrade the FPD image running on the SPA or SIP when you upgrade the Cisco IOS XR software image. However, if you enable the fpd auto-upgrade command in administration configuration mode, FPD images are automatically updated whenever you perform a software upgrade. For the automatic FPD upgrade to work, the following conditions must be met:

  • The FPD package installation envelope (PIE) must already be installed on the router.
  • The FPD PIE must be activated together with the new Cisco IOS XR image.
  • The fpd auto-upgrade command must be enabled.

Note

Although the FPD upgrade is performed during the install operation, there is no install commit performed. Therefore, once the FPD has been upgraded, if the image is rolled back to the original version, the FPD version is not downgraded to the previous version.

The automatic FPD upgrade is not performed in the following instances:

  • Line cards or other cards such as RSPs, SPAs or alarm cards are added to an existing router.
  • A non-reload software maintenance upgrade (SMU) or PIE installation is performed, even where the FPD image version changes. Since a non-reload installation is, by definition, not supposed to reload the router, and an FPD upgrade requires a router reload, the automatic FPD upgrade is repressed.

Note

In all cases where the automatic FPD upgrade is not performed, you must perform a manual FPD upgrade using the upgrade hw-module fpd command.

How to Upgrade FPD Images

You must determine if an FPD image upgrade is needed using the show hw-module fpd command and perform the upgrade, if needed, under the following circumstances:

  • You migrate the software to a later Cisco IOS XR software release.
  • You swap SPAs or SIPs from a system running a different Cisco IOS XR software release.
  • You insert a new SPA or SIP.

In the event that there is an FPD incompatibility with your card, you may receive an error message. If you upgrade to a newer version of the Cisco IOS XR software and there is an FPD incompatibility, you receive the following message:

LC/0/1/CPU0:Dec 23 16:33:47.945 : spa_192_jacket_v2[203]: %PLATFORM-UPGRADE_FPD-4-DOWN_REV : spa fpga2 instance 0 is down-rev (V0.6), upgrade to (V1.0). Use the "upgrade hw-module fpd" CLI in admin mode.

If the FPD image on the card is newer then what is required by the currently running Cisco IOS XR software image on the router, you receive the following error message:

LC/0/1/CPU0:Dec 23 16:33:47.955 : spa_192_jacket_v2[203]: %PLATFORM-UPGRADE_FPD-4-UP_REV : spa fpga instance 1 is severely up-rev (V2.1), downgrade to (V1.6). Use the "upgrade hw-module fpd" CLI in admin mode.

You should perform the FPD upgrade procedure if you receive such messages. Cards may not function properly if FPD incompatibilities are not resolved.


Note

The use of the force option when performing a FDP upgrade is not recommended except under explicit direction from Cisco engineering or TAC.

Before You Begin
  • Before upgrading the FPD, you must install and activate the asr9k-fpd.pie. For information about performing this task, see the Upgrading and Managing Cisco IOS XR Software module.
  • The FPD upgrade procedure is performed while the card is online. At the end of the procedure the card must be reloaded before the FPD upgrade is complete. To automatically reload the card, you can use the hw-module reload command during your next maintenance window. The upgrade procedure is not complete until the card is reloaded.
  • During the FPD upgrade, you must not do the following:
    • Reload, perform an online insertion and removal (OIR) of a line card (LC), or power down the chassis. Doing so may cause the node to enter an unusable state.
    • Press Ctrl-C if the console appears to hang without any output. Doing so may abort the upgrade.
  • If you are not sure whether a card requires an FPD upgrade, you can install the card and use the show hw-module fpd command to determine if the FPD image on the card is compatible with the currently running Cisco IOS XR software release.
SUMMARY STEPS

    1.    show hw-module fpd location {all | node-id}

    2.    admin

    3.    (Optional) show fpd package

    4.    upgrade hw-module fpd {all | fpga-type} [ force] location [all | node-id]

    5.    exit

    6.    (Optional) hw-module {location node-id | subslot subslot-id} reload

    7.    show platform


DETAILED STEPS
     Command or ActionPurpose
    Step 1 show hw-module fpd location {all | node-id}


    Example: 
    RP/0/RSP0/CPU0:router# show hw-module fpd location all

    or

    RP/0/RSP0/CPU0:router# show hw-module fpd location 0/4/cpu0
     

    Displays the current FPD image versions for the specified card or all cards installed in the router. Use this command to determine if you must upgrade the FPD image on your card.

     
    Step 2 admin


    Example: 
    RP/0/RSP0/CPU0:router# admin
     

    Enters administration EXEC mode.

     
    Step 3 show fpd package


    Example: 
    RP/0/RSP0/CPU0:router(admin)# show fpd package
          		(Optional)

    Displays which cards are supported with your current Cisco IOS XR software release, which FPD image you need for each card, and what the minimum hardware requirements are for the various modules. (A minimum hardware requirement version of 0.0 indicates that all hardware can support this FPD image version.)

    If there are multiple FPD images for your card, use this command to determine which FPD image to use if you want to upgrade only a specific FPD type.

     
    Step 4 upgrade hw-module fpd {all | fpga-type} [ force] location [all | node-id]


    Example: 
    RP/0/RSP0/CPU0:router(admin)# upgrade hw-module fpd 
all location 0/3/1 
.
.
.
Successfully upgraded 1 FPD for SPA-2XOC48POS/RPR 
  on location 0/3/1
     

    Upgrades all the current FPD images that must be upgraded on the specified card with new images.

    Before continuing to the next step, wait for confirmation that the FPD upgrade has successfully completed. Status messages, similar to these, are displayed to the screen until the FPD upgrade is completed:

    FPD upgrade started.
FPD upgrade in progress..
FPD upgrade in progress..
FPD upgrade sent to location xxxx
FPD upgrade sent to location yyyy
FPD upgrade in progress..
FPD upgrade finished for location xxx
FPD upgrade in progress..
FPD upgrade finished for location yyyy
FPD upgrade completed.

    The “FPD upgrade in progress.” message is printed every minute. These logs are information logs, and as such, are displayed if the logging console informational command is configured.

    If Ctrl-C is pressed while the FPD upgrade is in progress, the following warning message is displayed:

    FPD upgrade in progress on some hardware, 
aborting now is not recommended as it might 
cause HW programming failure and result in 
RMA of the hardware.
Do you want to continue? [Confirm(y/n)]

    If you confirm that you want to abort the FPD upgrade procedure, this message is displayed:

     
FPD upgrade process has been aborted, please 
check the status of the hardware and reissue 
the upgrade command if required.
    Note   

    If your card supports multiple FPD images, you can use the show fpd package admin command to determine what specific image to upgrade in the upgrade hw-module fpd command.

     
    Step 5 exit


    Example: 
    RP/0/RSP0/CPU0:router(admin)# exit
     

    Exits administration EXEC mode and returns to EXEC mode.

     
    Step 6 hw-module {location node-id | subslot subslot-id} reload


    Example: 
    RP/0/RSP0/CPU0:router# hw-module subslot 0/3/1 reload

    or 

    RP/0/RSP0/CPU0:router# hw-module location 0/3/cpu0 reload
          		(Optional)

    Use the hw-module subslot reload command to reload a SPA and the hw-module location reload command to reload a SIP or line card.

     
    Step 7 show platform


    Example: 
    RP/0/RSP0/CPU0:router# show platform
     

    Verifies that the FPD image on the card has been successfully upgraded by displaying the status of all cards in the system.

     

    Configuration Examples for FPD Image Upgrade

    The following examples indicates the use of commands associated with the FPD image upgrade procedure.

    show hw-module fpd Command Output: Example

    Use the show hw-module fpd to display the current version of FPD images on the SPAs, SIPs and other cards installed on your router.

    This command can be used to identify information about FPDs on any card. If you enter the location of a line card that is not a SPA, the output displays information about any programmable devices on that line card.

    The following example shows how to display FPD compatibility for all modules in the router: 

    RP/0/RSP1/CPU0:router# show hw-module fpd location all

    Field

    Description

    Card Type

    Module part number.

    FPD Description

    Description of all FPD images available for the SPA.

    Type

    Hardware type. Possible types can be:

    • spa—Shared port adapter
    • lc—Line card

    Subtype

    FPD subtype. These values are used in the upgrade hw-module fpd command to indicate a specific FPD image type to upgrade.

    SW Version

    FPD software version recommended for the associated module running the current Cisco IOS XR software.

    Min Req SW Vers

    Minimum required FPD image software version to operate the card. Version 0.0 indicates that a minimum required image was not programmed into the card.

    Min Req HW Vers

    Minimum required hardware version for the associated FPD image. A minimum hardware requirement of version 0.0 indicates that all hardware can support this FPD image version.


    Note

    In the show fpd package command output, the “subtype” column shows the FPDs that correspond with each SPA image. To upgrade a specific FPD with the upgrade hw-module fpd command, replace the fpga-type argument with the appropriate FPD from the “subtype” column, as shown in the following example: 

    RP/0/RSP0/CPU0:router(admin)# upgrade hw-module fpd fpga2 location 0/3/1 reload

    upgrade hw-module fpd Command Output: Example

    Use the upgrade hw-module fpd command to upgrade the FPD image on a SPA, SIP or line card.

    RP/0/RSP0/CPU0:router# admin
RP/0/RSP0/CPU0:router(admin)# upgrade hw-module fpd fpga location 0/1/cpu0

 Mon Jan 12 05:44:37.611 PST 

% RELOAD REMINDER:  - The upgrade operation of the target module will not interrupt its normal
    operation. However, for the changes to take effect, the target module
    will need to be manually reloaded after the upgrade operation. This can
    be accomplished with the use of "hw-module <target> reload" command.
  - If automatic reload operation is desired after the upgrade, please use
    the "reload" option at the end of the upgrade command.
  - The output of "show hw-module fpd location" command will not display
    correct version information after the upgrade if the target module is
    not reloaded.

    Troubleshooting Problems with FPD Image Upgrades

    This section contains information to help troubleshoot problems that can occur during the upgrade process.

    Power Failure or Removal of a SPA During an FPD Image Upgrade

    If the FPD upgrade operation is interrupted by a power failure or the removal of the SPA, it could corrupt the FPD image. This corruption of the FPD image file makes the SPA unusable by the router and the system displays the following messages when it tries to power up the SPA. When it cannot successfully power up the SPA, it places it in the failed state, as shown in the following example:

    LC/0/3/CPU0:Feb  4 08:23:16.672 : spa_192_jacket[188]: %L2-SPA-5-OIR_INSERTED : SPA discovered in bay 0
  LC/0/3/CPU0:Feb  4 08:23:23.349 : spa_192_jacket[188]: %L2-SPA-5-OIR_ERROR : SPA (0): An error occurred (0x1002), error recovery action: reset SPA
  LC/0/3/CPU0:Feb  4 08:23:26.431 : spa_192_jacket[188]: %L2-SPA-5-OIR_INSERTED : SPA discovered in bay 0
  LC/0/3/CPU0:Feb  4 08:23:32.593 : spa_192_jacket[188]: %L2-SPA-5-OIR_ERROR : SPA (0): Too many retries, error recovery stopped
  LC/0/3/CPU0:Feb  4 08:23:32.593 : spa_192_jacket[188]: %L2-SPA-5-OIR_ERROR : SPA (0): An error occurred (0x1002), error recovery action: hold SPA in reset

    When a SPA is in the failed state, it may not register itself with the FPD upgrade mechanism. In this case, you do not see the SPA listed when you use the show hw-module fpd command. To verify the state of a SPA, use the show hw-module subslot error command and the show hw-module subslot status command.

    Performing a SPA FPD Recovery Upgrade

    To recover a SPA from the failed state because of a corrupted FPD image, you must manually shut down the SPA. Use the hw-module subslot subslot-id shutdown command in global configuration mode to administratively shutdown the SPA. After the SPA is shut down, you can use the upgrade hw-module fpd command in administration EXEC mode: 

    RP/0/RSP0/CPU0:router# admin
RP/0/RSP0/CPU0:router(admin)# upgrade hw-module fpd fpga location 0/3/0

    Performing a SIP FPD Recovery Upgrade

    If a SIP upgrade fails for whatever reason, do not reload the SIP. Try to perform the upgrade procedure again. You can perform the upgrade procedure multiple times, as long as you do not reload the SIP. The FPD upgrade procedure takes several minutes to complete; do not interrupt the procedure. If you reload the SIP when the FPD image is corrupted, the SIP malfunctions and you must contact Cisco technical support for assistance.

    To recover a SIP from the failed state because of a corrupted FPD image, you must contact Cisco technical support.

    To recover a SIP from the failed state because of a corrupted FPD image, you must turn off the automatic reset of the SIP card. Use the hw-module reset auto disable command in administration configuration mode, as shown in the following example: 

    RP/0/RSP0/CPU0:router(admin-config)# hw-module reset auto disable location 0/1/4
