Configuring UCS Components for VM-FEX

This chapter includes the following sections:

Creating a Dynamic vNIC Connection Policy for VM-FEX for Hyper-V

The vNICs created by this procedure become VFs when they are associated with an SR-IOV PF in a service profile. The maximum number of VFs that you can create depends on the number of adapters and the number of configured PFs and vHBAs, according to the following formula:

Number of dynamic vNICs = (116 * number of adapters) - number of PFs - number of vHBAs

Before You Begin

For more information on dynamic vNIC connection policies, see Configuring Policies.

Procedure
      Command or Action Purpose
    Step 1 UCS-A# scope org org-name  

    Enters organization mode for the specified organization. To enter the root organization mode, enter / as the org-name .

     
    Step 2 UCS-A /org # create dynamic-vnic-conn-policy policy-name  

    Creates the specified vNIC connection policy and enters organization vNIC connection policy mode.

    The policy-name can be between 1 and 32 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen) or _ (underscore), and you cannot change this name after the object has been saved.

    Note   

    Do not specify "default" as the value for the dynamic vNIC connection policy name. Cisco UCS Manager automatically resolves any empty policy references to "default". Any service profiles or service profile templates with only static vNICS defined will automatically reference the policy "default" when it is present. If you specify “default” for the dynamic vNIC connection policy name, then unexpected dynamic vNICs might be created on those service profiles or service profile templates.

     
    Step 3 UCS-A /org/dynamic-vnic-conn-policy # set desc description   (Optional)

    Provides a description for the policy.

    Enter up to 256 characters. You can use any characters or spaces except ` (accent mark), \ (backslash), ^ (carat), " (double quote), = (equal sign), > (greater than), < (less than), or ' (single quote).

    If your description includes spaces or nonalphanumeric characters, you must begin and end your description with double quotation marks. The quotation marks do not appear in the description field of any show command output.

     
    Step 4 UCS-A /org/dynamic-vnic-conn-policy # set adapter-policy policy-name  

    Specifies the Ethernet adapter policy to use for this policy. The adapter policy must already exist.

    For Hyper-V, specify the predefined Windows adapter policy.

     
    Step 5 UCS-A /org/dynamic-vnic-conn-policy # set dynamic-eth {dynamic-eth-num | off}  

    Specifies the number of dynamic vNICs to use for this policy.

    Enter an integer between 0 and the maximum number as determined by the following formula:

    Number of dynamic vNICs = (116 * number of adapters) - number of PFs - number of vHBAs

     
    Step 6 UCS-A /org/dynamic-vnic-conn-policy # set protection {protected | protected-pref-a | protected-pref-b}   (Optional)
    Dynamic vNICs are always protected in Cisco UCS, but this command allows you to select a preferred fabric, if any. You can choose one of the following options:
    • protected—Cisco UCS uses whichever fabric is available.
    • protected-pref-a—Cisco UCS attempts to use fabric A, but fails over to fabric B if necessary.
    • protected-pref-b—Cisco UCS attempts to use fabric B, but fails over to fabric A if necessary.
     
    Step 7 UCS-A /org/dynamic-vnic-conn-policy # commit-buffer  

    Commits the transaction.

     

    The following example shows how to create a dynamic vNIC connection policy named MyDynVnicConnPolicy that uses the predefined Windows adapter policy for 21 dynamic vNICs and commit the transaction: 

    UCS-A# scope org /
UCS-A /org # create dynamic-vnic-conn-policy MyDynVnicConnPolicy
UCS-A /org/dynamic-vnic-conn-policy* # set adapter-policy Windows 
UCS-A /org/dynamic-vnic-conn-policy* # set desc "Dynamic vNIC for Eth policy"
UCS-A /org/dynamic-vnic-conn-policy* # set dynamic-eth 21
UCS-A /org/dynamic-vnic-conn-policy* # commit-buffer
UCS-A /org/dynamic-vnic-conn-policy #

    Configuring a Service Profile for VM-FEX for Hyper-V

    Creating a Service Profile for VM-FEX for Hyper-V

    The service profile created by this procedure configures the BIOS settings required for Hyper-V.

    Before You Begin

    For more information on configuring service profiles, see the Cisco UCS Manager CLI Configuration Guide.

    Procedure
        Command or Action Purpose
      Step 1 UCS-A# scope org org-name  

      Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name .

       
      Step 2 UCS-A /org # create service-profile profile-name instance  

      Creates the specified service profile instance and enters organization service profile mode.

      Enter a unique profile-name to identify this service profile.

      This name can be between 2 and 32 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and this name must be unique across all service profiles and service profile templates within the same organization.

       
      Step 3 UCS-A /org/service-profile # set bios-policy SRIOV  

      The predefined SRIOV BIOS policy configures the required BIOS settings for Hyper-V.

       
      Step 4 Configure other desired profile settings, but do not configure a dynamic vNIC connection policy.   

      The following example shows how to create a service profile instance and commit the transaction: 

      UCS-A# scope org /
UCS-A /org # create service-profile SPHyperV instance
UCS-A /org/service-profile* # set bios-policy SRIOV
UCS-A /org/service-profile* # commit-buffer
UCS-A /org/service-profile #
      What to Do Next

      • Create PF vNIC for the service profile.
      • Associate the service profile with a server.

      Creating the PF Interface

      This procedure creates the SR-IOV PF interface.

      Before You Begin

      For more information on configuring service profiles, see the Cisco UCS Manager CLI Configuration Guide.

      Procedure
          Command or Action Purpose
        Step 1 UCS-A# scope org org-name  

        Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name .

         
        Step 2 UCS-A /org # scope service-profile profile-name

        Step 4 UCS-A /org/service-profile/vnic # set adapter-policy SRIOV  

        Specifies the SRIOV adapter policy to use for the vNIC.

        Note   

        The predefined SRIOV adapter policy supports up to 32 CPU threads. If the server has more than 32 CPU threads, you must create and specify a custom adapter policy that supports a number of interrupts equal to the number of CPU threads. Follow the instructions in Creating a Custom Adapter Policy for SR-IOV.
         
        Step 5 UCS-A /org/service-profile/vnic # create dynamic-conn-policy-ref dynamic-conn-policy-name   Specify the dynamic vNIC connection policy that you created using the predefined Windows adapter policy. 
        Step 6 Configure other desired profile settings.   
        Step 7 UCS-A /org/service-profile/vnic # exit  

        Returns to service-profile mode.

         
        Step 8 UCS-A /org/service-profile # commit-buffer  

        Commits the transaction to the system configuration.

         

        The following example shows how to create a PF interface and commit the transaction:
