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.

Configuring vHBA Templates
This template is a policy that defines how a vHBA on a server connects to the SAN. It is also referred to as a vHBA SAN connectivity template.
You need to include this policy in a service profile for it to take effect.
This policy requires that one or more of the following resources already exist in the system:
Include the vHBA template in a service profile.
Step 1 | In the Navigation pane, click the SAN tab. |
Step 2 | On the SAN tab, expand . |
Step 3 | Expand the vHBA Templates node. |
Step 4 | Right-click the vHBA template that you want to delete and choose Delete. |
Step 5 | If Cisco UCS Manager GUI displays a confirmation dialog box, click Yes. |
You can bind a vHBA associated with a service profile to a vHBA template. When you bind the vHBA to a vHBA template, Cisco UCS Manager configures the vHBA with the values defined in the vHBA template. If the existing vHBA configuration does not match the vHBA template, Cisco UCS Manager reconfigures the vHBA. You can only change the configuration of a bound vHBA through the associated vHBA template. You cannot bind a vHBA to a vHBA template if the service profile that includes the vHBA is already bound to a service profile template.
If the vHBA is reconfigured when you bind it to a template, Cisco UCS Manager reboots the server associated with the service profile.
Step 1 | In the Navigation pane, click the Servers tab. |
Step 2 | On the Servers tab, expand . |
Step 3 |
Expand the node for the organization that includes the service profile with the vHBA you want to bind. If the system does not include multi-tenancy, expand the root node. |
Step 4 | Expand . |
Step 5 | Click the vHBA you want to bind to a template. |
Step 6 | In the Work pane, click the General tab. |
Step 7 | In the Actions area, click Bind to a Template. |
Step 8 | In the Bind to a vHBA Template dialog box, do the following: |
Step 9 | In the warning dialog box, click Yes to acknowledge that Cisco UCS Manager may need to reboot the server if the binding causes the vHBA to be reconfigured. |
Step 1 | In the Navigation pane, click the Servers tab. |
Step 2 | On the Servers tab, expand . |
Step 3 |
Expand the node for the organization that includes the service profile with the vHBA you want to unbind. If the system does not include multi-tenancy, expand the root node. |
Step 4 | Expand . |
Step 5 | Click the vHBA you want to unbind from a template. |
Step 6 | In the Work pane, click the General tab. |
Step 7 | In the Actions area, click Unbind from a Template. |
Step 8 | If Cisco UCS Manager GUI displays a confirmation dialog box, click Yes. |
Configuring Fibre Channel Adapter Policies
These policies govern the host-side behavior of the adapter, including how the adapter handles traffic. For example, you can use these policies to change default settings for the following:
Queues
Interrupt handling
Performance enhancement
RSS hash
Failover in an cluster configuration with two fabric interconnects

For Fibre Channel adapter policies, the values displayed by Cisco UCS Manager may not match those displayed by applications such as QLogic SANsurfer. For example, the following values may result in an apparent mismatch between SANsurfer and Cisco UCS Manager:

By default, Cisco UCS provides a set of Ethernet adapter policies and Fibre Channel adapter policies. These policies include the recommended settings for each supported server operating system. Operating systems are sensitive to the settings in these policies. Storage vendors typically require non-default adapter settings. You can find the details of these required settings on the support list provided by those vendors.
We recommend that you use the values in these policies for the applicable operating system. Do not modify any of the values in the default policies unless directed to do so by Cisco Technical Support.
However, if you are creating an Ethernet adapter policy for a Windows OS (instead of using the default Windows adapter policy), you must use the following formulas to calculate values that work with Windows:
For example, if Transmit Queues = 1 and Receive Queues = 8 then:
