Downloading and Managing Firmware in Cisco UCS Manager

Downloading and Managing Firmware in Cisco UCS Manager

This chapter includes the following sections:

Firmware Image Management

Cisco delivers all firmware updates to Cisco UCS components in bundles of images. Cisco UCS firmware updates are available to be downloaded to fabric interconnects in a Cisco UCS domain in the following bundles:

Cisco UCS Infrastructure Software Bundle

This bundle includes the following firmware images that are required to update the following components:

  • Cisco UCS Manager software
  • Kernel and system firmware for the fabric interconnects
  • I/O module firmware
Cisco UCS B-Series Blade Server Software Bundle

This bundle includes the following firmware images that are required to update the firmware for the blade servers in a Cisco UCS domain. In addition to the bundles created for a release, these bundles can also be released between infrastructure bundles to enable Cisco UCS Manager to support a blade server that is not included in the most recent infrastructure bundle.

  • CIMC firmware
  • BIOS firmware
  • Adapter firmware
  • Board controller firmware
  • Third-party firmware images required by the new server
Cisco UCS C-Series Rack-Mount UCS-Managed Server Software Bundle

This bundle includes the following firmware images that are required to update components on rack-mount servers that have been integrated with and are managed by Cisco UCS Manager:

  • CIMC firmware
  • BIOS firmware
  • Adapter firmware
  • Storage controller firmware

Note


You cannot use this bundle for standalone C-series servers. The firmware management system in those servers cannot interpret the header required by Cisco UCS Manager. For information on how to upgrade standalone C-series servers, see the C-series configuration guides.


Cisco also provides release notes, which you can obtain on the same website from which you obtained the bundles.

Firmware Image Headers

Every firmware image has a header, which includes the following:

  • Checksum
  • Version information
  • Compatibility information that the system can use to verify the compatibility of component images and any dependencies

Firmware Image Catalog

Cisco UCS Manager provides you with two views of the catalog of firmware images and their contents that have been downloaded to the fabric interconnect:

Packages

This view provides you with a read-only representation of the firmware bundles that have been downloaded onto the fabric interconnect. This view is sorted by image, not by the contents of the image. For packages, you can use this view to see which component images are in each downloaded firmware bundle.

Images

The images view lists the component images available on the system. You cannot use this view to see complete firmware bundles or to group the images by bundle. The information available about each component image includes the name of the component, the image size, the image version, and the vendor and model of the component.

You can use this view to identify the firmware updates available for each component. You can also use this view to delete obsolete and unneeded images. Cisco UCS Manager deletes a package after all images in the package have been deleted.


Tip


Cisco UCS Manager stores the images in bootflash on the fabric interconnect. In a cluster system, space usage in bootflash on both fabric interconnects is the same, because all images are synchronized between them. If Cisco UCS Manager reports that the bootflash is out of space, delete obsolete images to free up space.


Obtaining Software Bundles from Cisco

Before You Begin

Determine which of the following software bundles you need to update the Cisco UCS domain:

  • Cisco UCS Infrastructure Software Bundle—Required for all Cisco UCS domains.

    Downloading Firmware Images to the Fabric Interconnect from a Remote Location


    Note


    In a cluster setup, the image file for the firmware bundle is downloaded to both fabric interconnects, regardless of which fabric interconnect is used to initiate the download. Cisco UCS Manager maintains all firmware packages and images in both fabric interconnects in sync. If one fabric interconnect is down, the download still finishes successfully. The images are synced to the other fabric interconnect when it comes back online.


    Before You Begin

    Obtain the required firmware bundles from Cisco.

    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   Click the Installed Firmware tab.
      Step 5   Click Download Firmware.
      Step 6   In the Download Firmware dialog box, click the Remote File System radio button in the Location of the Image File field.
      Step 7   Complete the following fields:
      Name Description

      Protocol field

      The protocol to use when communicating with the remote server. This can be one of the following:

      • FTP
      • TFTP
      • SCP
      • SFTP
      Note   

      TFTP has a file size limitation of 32 MB. Because firmware bundles can be much larger than that, we recommend that you do not choose TFTP for firmware downloads.

      Server field

      If the file came from a remote server, this is the IP address or hostname of the remote server on which the files resides. If the file came from a local source, this field displays "local".

      Note   

      If you use a hostname rather than an IPv4 or IPv6 address, you must configure a DNS server. If the Cisco UCS domain is not registered with Cisco UCS Central or DNS management is set to local, configure a DNS server in Cisco UCS Manager. If the Cisco UCS domain is registered with Cisco UCS Central and DNS management is set to global, configure a DNS server in Cisco UCS Central.

      Filename field

      The name of the firmware file.

      Path field

      The absolute path to the file on the remote server.

      If you use SCP, the absolute path is always required. If you use any other protocol, you may not need to specify a remote path if the file resides in the default download folder. For details about how your file server is configured, contact your system administrator.

      User field

      The username the system should use to log in to the remote server. This field does not apply if the protocol is TFTP.

      Password field

      The password for the remote server username. This field does not apply if the protocol is TFTP.

      Step 8   Click OK.

      Cisco UCS Manager GUI begins downloading the firmware bundle to the fabric interconnect.

      Step 9   (Optional)Monitor the status of the download on the Download Tasks tab.
      Note   

      If Cisco UCS Manager reports that the bootflash is out of space, delete obsolete bundles on the Packages tab to free up space. To view the available space in bootflash, navigate to the fabric interconnect on the Equipment tab and expand the Local Storage Information area on the General tab.

      Step 10   Repeat this task until all the required firmware bundles have been downloaded to the fabric interconnect.

      What to Do Next

      After the image file for the firmware bundles have downloaded completely, update the firmware on the endpoints.

      Downloading Firmware Images to the Fabric Interconnect from the Local File System


      Note


      In a cluster setup, the image file for the firmware bundle is downloaded to both fabric interconnects, regardless of which fabric interconnect is used to initiate the download. Cisco UCS Manager maintains all firmware packages and images in both fabric interconnects in sync. If one fabric interconnect is down, the download still finishes successfully. The images are synced to the other fabric interconnect when it comes back online.


      Before You Begin

      Obtain the required firmware bundles from Cisco.

      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   Click the Installed Firmware tab.
        Step 5   Click Download Firmware.
        Step 6   In the Download Firmware dialog box, click the Local File System radio button in the Location of the Image File field.
        Step 7   In the Filename field, type the full path and and name of the image file.

        If you do not know the exact path to the folder where the firmware image file is located, click Browse and navigate to the file.

        Step 8   Click OK.

        Cisco UCS Manager GUI begins downloading the firmware bundle to the fabric interconnect.

        Step 9   (Optional)Monitor the status of the firmware bundle download on the Download Tasks tab.
        Note   

        If Cisco UCS Manager reports that the bootflash is out of space, delete obsolete bundles on the Packages tab to free up space. To view the available space in bootflash, navigate to the fabric interconnect on the Equipment tab and expand the Local Storage Information area on the General tab.

        Step 10   Repeat this task until all the required firmware bundles have been downloaded to the fabric interconnect.

        What to Do Next

        After the image file for the firmware bundles have downloaded completely, update the firmware on the endpoints.

        Canceling an Image Download

        You can cancel the download task for an image only while it is in progress. After the image has downloaded, deleting the download task does not delete the image that was downloaded. You cannot cancel the FSM related to the image download task.

        Procedure
          Step 1   In the Navigation pane, click the Equipment tab.
          Step 2   Expand the Equipment node.
          Step 3   In the Work pane, click the Firmware Management tab.
          Step 4   On the Download Tasks tab, right-click the task you want to cancel and select Delete.

          Determining the Contents of a Firmware Package

          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 Packages subtab, click the + icon next to a package to view its contents.
            Step 5   To take a snapshot of the package contents, do the following:
            1. Highlight the rows that include the image name and its contents.
            2. Right-click and choose Copy.
            3. Paste the contents of your clipboard into a text file or other document.

            Checking the Available Space on a Fabric Interconnect

            If an image download fails, check whether the bootflash on the fabric interconnect or fabric interconnects in the Cisco UCS has sufficient available space.

            Procedure
              Step 1   In the Navigation pane, click the Equipment tab.
              Step 2   On the Equipment tab, expand Equipment > Fabric Interconnects.
              Step 3   Click the fabric interconnect on which you want to check the available space.
              Step 4   In the Work pane, click the General tab.
              Step 5   Expand the Local Storage Information area.

              When you download a firmware image bundle, a fabric interconnect needs at least twice as much available space as the size of the firmware image bundle. If the bootflash does not have sufficient space, delete the obsolete firmware, core files, and other unneeded objects from the fabric interconnect.


              Deleting Firmware Packages from a Fabric Interconnect

              Use this procedure if you want to delete an entire firmware package or bundle. If you prefer you can also delete one or more of the individual images in a package.

              For releases prior to Cisco UCS, Release 1.3(1), you cannot delete firmware packages from the Packages tab. After you delete all images from the package, Cisco UCS Manager removes the packages.

              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 Firmware Management tab, click the Packages tab.
                Step 5   In the table, click the package that you want to delete.

                You can use the Shift key or Ctrl key to select multiple entries.

                Step 6   Right-click the highlighted package or packages and choose Delete.
                Step 7   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

                Cisco UCS Manager deletes the selected package or packages and all images contained within each package.

                Deleting Firmware Images from a Fabric Interconnect

                Use this procedure if you want to delete only a single image from a package.

                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 Firmware Management tab, click the Images tab.
                  Step 5   In the table, click the image that you want to delete.

                  You can use the Shift key or Ctrl key to select multiple entries.

                  Step 6   Right-click the highlighted image or images and choose Delete.
                  Step 7   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.
