Directly Upgrading Firmware at Endpoints

This chapter includes the following sections:

Direct Firmware Upgrade at Endpoints

If you follow the correct procedure and apply the upgrades in the correct order, a direct firmware upgrade and the activation of the new firmware version on the endpoints is minimally disruptive to traffic in a Cisco UCS domain.

You can directly upgrade the firmware on the following endpoints:

  • Adapters
  • CIMCs
  • I/O modules
  • Board controllers
  • Cisco UCS Manager
  • Fabric interconnects

The adapter and board controller firmware can also be upgraded through the host firmware package in the service profile. If you use a host firmware package to upgrade this firmware, you can reduce the number of times a server needs to be rebooted during the firmware upgrade process.


Note


Upgrades of a CIMC through a management firmware package or an adapter through a firmware package in the service profile associated with the server take precedence over direct firmware upgrades. You cannot directly upgrade an endpoint if the service profile associated with the server includes a firmware package. To perform a direct upgrade, you must remove the firmware package from the service profile.


Stages of a Direct Firmware Upgrade

Cisco UCS Manager separates the direct upgrade process into two stages to ensure that you can push the firmware to an endpoint while the system is running without affecting uptime on the server or other endpoints.

Update

During this stage, the system copies the selected firmware version from the primary fabric interconnect to the backup partition in the endpoint and verifies that the firmware image is not corrupt. The update process always overwrites the firmware in the backup slot.

The update stage applies only to the following endpoints:

  • Adapters
  • CIMCs
  • I/O modules

Caution


Do not remove the hardware that contains the endpoint or perform any maintenance on it until the update process has completed. If the hardware is removed or otherwise unavailable due to maintenance, the firmware update fails. This failure may corrupt the backup partition. You cannot update the firmware on an endpoint with a corrupted backup partition.


Activate

During this stage, the system sets the specified image version (normally the backup version) as the startup version and, if you do not specify Set Startup Version Only, immediately reboots the endpoint. When the endpoint is rebooted, the backup partition becomes the active partition, and the active partition becomes the backup partition. The firmware in the new active partition becomes the startup version and the running version.

The following endpoints only require activation because the specified firmware image already exists on the endpoint:

  • Cisco UCS Manager
  • Fabric interconnects
  • Board controllers on those servers that support them

When the firmware is activated, the endpoint is rebooted and the new firmware becomes the active kernel version and system version. If the endpoint cannot boot from the startup firmware, it defaults to the backup version and raises a fault.


Caution


When you configure Set Startup Version Only for an I/O module, the I/O module is rebooted when the fabric interconnect in its data path is rebooted. If you do not configure Set Startup Version Only for an I/O module, the I/O module reboots and disrupts traffic. In addition, if Cisco UCS Manager detects a protocol and firmware version mismatch between the fabric interconnect and the I/O module, Cisco UCS Manager automatically updates the I/O module with the firmware version that matches the firmware in the fabric interconnect and then activates the firmware and reboots the I/O module again.


Outage Impacts of Direct Firmware Upgrades

When you perform a direct firmware upgrade on an endpoint, you can disrupt traffic or cause an outage in one or more of the endpoints in the Cisco UCS domain.

Outage Impact of a Fabric Interconnect Firmware Upgrade

When you upgrade the firmware for a fabric interconnect, you cause the following outage impacts and disruptions:

  • The fabric interconnect reboots.
  • The corresponding I/O modules reboot.

Outage Impact of a Cisco UCS Manager Firmware Upgrade

A firmware upgrade to Cisco UCS Manager causes the following disruptions:

  • Cisco UCS Manager GUI—All users logged in to Cisco UCS Manager GUI are logged out and their sessions ended. Any unsaved work in progress is lost.
  • Cisco UCS Manager CLI—All users logged in through telnet are logged out and their sessions ended.

Outage Impact of an I/O Module Firmware Upgrade

When you upgrade the firmware for an I/O module, you cause the following outage impacts and disruptions:

  • For a standalone configuration with a single fabric interconnect, data traffic is disrupted when the I/O module reboots. For a cluster configuration with two fabric interconnects, data traffic fails over to the other I/O module and the fabric interconnect in its data path.
  • If you activate the new firmware as the startup version only, the I/O module reboots when the corresponding fabric interconnect is rebooted.
  • If you activate the new firmware as the running and startup version, the I/O module reboots immediately.
  • An I/O module can take up to ten minutes to become available after a firmware upgrade.

Outage Impact of a CIMC Firmware Upgrade

When you upgrade the firmware for a CIMC in a server, you impact only the CIMC and internal processes. You do not interrupt server traffic. This firmware upgrade causes the following outage impacts and disruptions to the CIMC:

  • Any activities being performed on the server through the KVM console and vMedia are interrupted.
  • Any monitoring or IPMI polling is interrupted.

Outage Impact of an Adapter Firmware Upgrade

If you activate the firmware for an adapter and do not configure the Set Startup Version Only option, you cause the following outage impacts and disruptions:

  • The server reboots.
  • Server traffic is disrupted.

Updating the Firmware on Multiple Endpoints

You can use this procedure to update the firmware on the following endpoints:

  • Adapters
  • CIMCs
  • I/O modules

Caution


Do not remove the hardware that contains the endpoint or perform any maintenance on it until the update process has completed. If the hardware is removed or otherwise unavailable due to maintenance, the firmware update fails. This failure may corrupt the backup partition. You cannot update the firmware on an endpoint with a corrupted backup partition.


Procedure
    Step 1   In the Navigation pane, click the Equipment tab.
    Step 2   On the Equipment tab, click the Equipment node.
    Step 3   In the Work pane, click the Firmware Management tab.
    Step 4   On the Installed Firmware tab, click Update Firmware.

    Cisco UCS Manager GUI opens the Update Firmware dialog box and verifies the firmware versions for all endpoints in the Cisco UCS domain. This step may take a few minutes, depending upon the number of chassis and servers.

    Step 5   In the Update Firmware dialog box, do the following:
    1. From the Filter drop-down list on the menu bar, select ALL.

      If you want to update all endpoint firmware of a specific type, such as all adapters or server BIOS, select that type from the drop-down list.

    2. In the Select field, do one of the following:
      • To activate all endpoints to the same version, click the Version radio button and select the appropriate version from the Set Version drop-down list.
      • To activate all endpoints to the firmware version included in a specific bundle, click the Bundle radio button and select the appropriate bundle from the Set Bundle drop-down list .
    3. Click OK.

      If one or more endpoints cannot be directly updated, Cisco UCS Manager displays a notification message. After you acknowledge the notification message, Cisco UCS Manager updates the firmware for all other endpoints on servers that can be directly updated.

    Cisco UCS Manager copies the selected firmware image to the backup memory partition and verifies that the image is not corrupt. The image remains as the backup version until you explicitly activate it. Cisco UCS Manager begins all updates at the same time. However, some updates may complete at different times.

    The update is complete when the Update Firmware dialog box displays ready in the Update Status column for all updated endpoints.

    Step 6   (Optional)To monitor the progress of the update to a specific endpoint, right-click the endpoint and choose Show Navigator.

    Cisco UCS Manager displays the progress in the Update Status area on the General tab. If the navigator has an FSM tab, you can also monitor the progress there. An entry in the Retry # field may not indicate that the update has failed. The retry count also includes retries that occur when Cisco UCS Manager retrieves the update status.


    What to Do Next

    Activate the firmware.

    Updating the Firmware on an Adapter


    Caution


    Do not remove the hardware that contains the endpoint or perform any maintenance on it until the update process has completed. If the hardware is removed or otherwise unavailable due to maintenance, the firmware update fails. This failure may corrupt the backup partition. You cannot update the firmware on an endpoint with a corrupted backup partition.


    Procedure
      Step 1   In the Navigation pane, click the Equipment tab.
      Step 2   On the Equipment tab, expand Equipment > Chassis > Chassis Number > Servers.
      Step 3   Expand the node for the server which includes the adapter you want to update.
      Step 4   Expand Adapters and select the adapter you want to upgrade.
      Step 5   In the General tab, click Update Firmware.
      Step 6   In the Update Firmware dialog box, do the following:
      1. From the Version drop-down list, select the firmware version to which you want to update the endpoint.
      2. Click OK.

        If one or more endpoints cannot be directly updated, Cisco UCS Manager displays a notification message. After you acknowledge the notification message, Cisco UCS Manager updates the firmware for all other endpoints on servers that can be directly updated.

      Cisco UCS Manager copies the selected firmware package to the backup memory slot, where it remains until you explicitly activate it.

      Step 7   (Optional)Monitor the status of the update in the Update Status area.

      The update process can take several minutes. Do not activate the firmware until the selected firmware package displays in the Backup Version field in the Firmware area of the General tab.


      What to Do Next

      Activate the firmware.

      Activating the Firmware on an Adapter

      Procedure
        Step 1   In the Navigation pane, click the Equipment tab.
        Step 2   On the Equipment tab, expand Equipment > Chassis > Chassis Number > Servers.
        Step 3   Expand the node for the server that includes the adapter for which you want to activate the updated firmware.
        Step 4   Expand Adapters and select the adapter for which you want to activate the firmware.
        Step 5   In the General tab, click Activate Firmware.
        Step 6   In the Activate Firmware dialog box, do the following:
        1. Select the appropriate version from the Version To Be Activated drop-down list.

          If one or more of the selected endpoints are not configured with the desired version as the backup version, Cisco UCS Manager GUI does not display that version in the Set Version drop-down list. You must select the version from the Startup Version column for each individual endpoint.

        2. If you want to set the start up version and not change the version running on the endpoint, check the Set Startup Version Only check box.

          During a direct upgrade, you should configure Set Startup Version Only for an adapter. With this setting, the activated firmware moves into the pending-next-boot state, and the server is not immediately rebooted. The activated firmware does not become the running version of firmware on the adapter until the server is rebooted. You cannot configure Set Startup Version Only for an adapter in the host firmware package.

          If a server is not associated with a service profile, the activated firmware remains in the pending-next-boot state. Cisco UCS Manager does not reboot the endpoints or activate the firmware until the server is associated with a service profile. If necessary, you can manually reboot or reset an unassociated server to activate the firmware.

        3. Click OK.

        Updating the BIOS Firmware on a Server


        Caution


        Do not remove the hardware that contains the endpoint or perform any maintenance on it until the update process has completed.

                          1. From the drop-down list in the Startup Version column, select the version to which you want to update the software.
                          2. Click OK.

                          Cisco UCS Manager disconnects all active sessions, logs out all users, and activates the software. When the upgrade is complete, you are prompted to log back in. If you are prompted to re-login immediately after being disconnected, the login will fail. You must wait until the activation of Cisco UCS Manager is completed, which takes a few minutes.

                          Cisco UCS Manager makes the selected version the startup version and schedules the activation to occur when the fabric interconnects are upgraded.


                          Activating the Firmware on a Subordinate Fabric Interconnect

                          Before You Begin

                          Determine which fabric interconnect in the cluster is the subordinate fabric interconnect.

                          Procedure
                            Step 1   In the Navigation pane, click the Equipment tab.
                            Step 2   On the Equipment tab, click the Equipment node.
                            Step 3   In the Work pane, click the Firmware Management tab.
                            Step 4   On the Installed Firmware tab, click Activate Firmware.

                            Cisco UCS Manager GUI opens the Activate Firmware dialog box and verifies the firmware versions for all endpoints in the Cisco UCS domain. This step may take a few minutes, depending upon the number of chassis and servers.

                            Step 5   From the Filter drop-down list on the menu bar, choose Fabric Interconnects.
                            Step 6   On the row of the Activate Firmware dialog box for the subordinate fabric interconnect, do the following:
                            1. In the Kernel row, choose the firmware version to which you want to upgrade from the drop-down list in the Startup Version column.
                            2. In the System row, choose the firmware version to which you want to upgrade from the drop-down list in the Startup Version column.
                            Step 7   Click Apply.

                            Cisco UCS Manager updates and activates the firmware and reboots the fabric interconnect and any I/O module in the data path to that fabric interconnect, disrupting data traffic to and from that fabric interconnect. However, assuming the Cisco UCS domain is configured to permit traffic and port failover, data traffic fails over to the primary fabric interconnect and is not disrupted.

                            Step 8   Verify the high availability status of the subordinate fabric interconnect.

                            If the High Availability Details area for the fabric interconnect does not show the following values, contact Cisco Technical Support immediately. Do not continue to update the primary fabric interconnect.

                            Field Name Required Value

                            Ready field

                            Yes

                            State field

                            Up


                            What to Do Next

                            If the high availability status of the subordinate fabric interconnect contains the required values, update and activate the primary fabric interconnect.

                            Activating the Firmware on a Primary Fabric Interconnect

                            This procedure continues directly from Activating the Firmware on a Subordinate Fabric Interconnect and assumes you are on the Firmware Management tab.

                            Before You Begin

                            Activate the subordinate fabric interconnect.

                            Procedure
                              Step 1   On the Installed Firmware tab, click Activate Firmware.

                              Cisco UCS Manager GUI opens the Activate Firmware dialog box and verifies the firmware versions for all endpoints in the Cisco UCS domain. This step may take a few minutes, depending upon the number of chassis and servers.

                              Step 2   From the Filter drop-down list on the menu bar, choose Fabric Interconnects.
                              Step 3   On the row of the Activate Firmware dialog box for the subordinate fabric interconnect, do the following:
                              1. In the Kernel row, choose the firmware version to which you want to upgrade from the drop-down list in the Startup Version column.
                              2. In the System row, choose the firmware version to which you want to upgrade from the drop-down list in the Startup Version column.
                              Step 4   Click Apply.

                              Cisco UCS Manager updates and activates the firmware and reboots the fabric interconnect and any I/O module in the data path to that fabric interconnect, disrupting data traffic to and from that fabric interconnect. However, assuming the Cisco UCS domain is configured to permit traffic and port failover, data traffic fails over to the other fabric interconnect, which becomes the primary. When it comes back up, this fabric interconnect is the subordinate fabric interconnect.

                              Step 5   Verify the high availability status of the fabric interconnect.

                              If the High Availability Details area for the fabric interconnect does not show the following values, contact Cisco Technical Support immediately.

                              Field Name Required Value

                              Ready field

                              Yes

                              State field

                              Up


                              Activating the Firmware on a Standalone Fabric Interconnect

                              For a standalone configuration with a single fabric interconnect, you can minimize the disruption to data traffic when you perform a direct firmware upgrade of the endpoints. However, you must reboot the fabric interconnect to complete the upgrade and, therefore, cannot avoid disrupting traffic.


                              Tip


                              If you ever need to recover the password to the admin account that was created when you configured the fabric interconnects for the Cisco UCS domain, you must know the running kernel version and the running system version. If you do not plan to create additional accounts, we recommend that you save the path to these firmware versions in a text file so that you can access them if required.


                              Procedure
                                Step 1   In the Navigation pane, click the Equipment tab.
                                Step 2   On the Equipment tab, click the Equipment node.
                                Step 3   Expand the Fabric Interconnects node and click the standalone fabric interconnect.
                                Step 4   On the General tab, click Activate Firmware.
                                Step 5   In the Activate Firmware dialog box, complete the following fields:
                                Name Description

                                Kernel Version drop-down list

                                Choose the version that you want to use for the kernel.

                                Force check box

                                If checked, Cisco UCS attempts the installation even if a previous attempt to install the selected version failed or was interrupted.

                                System Version drop-down list

                                Choose the version you want to use for the system.

                                Force check box

                                If checked, Cisco UCS attempts the installation even if a previous attempt to install the selected version failed or was interrupted.

                                Step 6   Click OK.

                                Cisco UCS Manager activates the firmware and reboots the fabric interconnect and any I/O module in the data path to that fabric interconnect. For a standalone fabric interconnect, this disrupts all data traffic in the Cisco UCS domain.

                                Verifying Firmware Versions on Components
