The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Use vHBA templates to define how a vHBA on a server connects to the SAN. You can view all existing vHBA templates on the Templates page.
Creating vHBA template pairs enables you to group vHBAs that belong to a specific server. For example, you can create a vHBA template and specify it as the primary template, then create a different vHBA template and specify it as the secondary template. You can link the two templates to create a pair that share attributes that you define in the primary template. The secondary template inherits the attributes from the primary template. If you select Updating Template, any changes made to the primary template are propagated to the secondary template in the template pair. You can also modify any non-shared configurations on each individual template in the pair.
When creating the pair, you can assign one template to each fabric. For example you could assign the primary template to fabric A, and the secondary template to fabric B. This eliminates the need to configure vHBA pairs independently using one or more templates. The number of vHBA pairs that can be created using a template pair is only limited by the adapter's maximum capabilities.
The following configurations are shared when using template pairs:
The following configurations are not shared when using template pairs:
Note |
If you plan to use a global vHBA redundancy template pair in a local service profile in Cisco UCS Manager, you cannot assign the vHBA template for the primary and the secondary of the redundancy template pair at the same time. You will need to assign the vHBA template for the primary vHBA and set the peer name for the second vHBA, then modify the secondary vHBA and manually assign the secondary vHBA template. |
Note |
Global vHBAs can be used in local service profiles created in Cisco UCS Manager. |
The host interface placement policy enables you to determine the user-specified virtual network interface connection (vCon) placement for vNICs and vHBAs.
To create a host interface placement policy, see Creating or Editing a Host Interface Placement Policy. Details for existing policies are displayed on the Host Interface Placement Policy page.
