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.

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.
The following example configures a vHBA template and commits the transaction:
UCS-A# scope org / UCS-A /org* # create vhba template VhbaTempFoo UCS-A /org/vhba-templ* # set descr "This is a vHBA template example." UCS-A /org/vhba-templ* # set fabric a UCS-A /org/vhba-templ* # set fc-if accounting UCS-A /org/vhba-templ* # set max-field-size 2112 UCS-A /org/vhba-templ* # set pin-group FcPinGroup12 UCS-A /org/vhba-templ* # set qos-policy policy34foo UCS-A /org/vhba-templ* # set stats-policy ServStatsPolicy UCS-A /org/vhba-templ* # set type updating-template UCS-A /org/vhba-templ* # set wwpn-pool SanPool7 UCS-A /org/vhba-templ* # commit-buffer UCS-A /org/vhba-templ #
The following example deletes the vHBA template named VhbaTempFoo and commits the transaction:
UCS-A# scope org / UCS-A /org # delete vhba template VhbaTempFoo UCS-A /org* # commit-buffer UCS-A /org #
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:
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:
The following example configures a Fibre Channel adapter policy and commits the transaction:
UCS-A# scope org / UCS-A /org* # create fc-policy FcPolicy42 UCS-A /org/fc-policy* # set descr "This is a Fibre Channel adapter policy example." UCS-A /org/fc-policy* # set error-recovery error-detect-timeout 2500 UCS-A /org/fc-policy* # set port max-luns 4 UCS-A /org/fc-policy* # set port-f-logi retries 250 UCS-A /org/fc-policy* # set port-p-logi timeout 5000 UCS-A /org/fc-policy* # set recv-queue count 1 UCS-A /org/fc-policy* # set scsi-io ring-size 256 UCS-A /org/fc-policy* # set trans-queue ring-size 256 UCS-A /org/fc-policy* # commit-buffer UCS-A /org/fc-policy #
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 # delete fc-policy policy-name | Deletes the specified Fibre Channel adapter policy. |
Step 3 | UCS-A /org # commit-buffer | Commits the transaction to the system configuration. |
The following example deletes the Fibre Channel adapter policy named FcPolicy42 and commits the transaction:
UCS-A# scope org / UCS-A /org # delete fc-policy FcPolicy42 UCS-A /org* # commit-buffer UCS-A /org #
