Enabling and Disabling SR-IOV on NIC Ports
Note: This section only applies when running the OneCommand Manager application
on supported SR-IOV adapters and operating system platforms.
Note: SR-IOV is not supported with UMC.
When SR-IOV is available, the NIC Port Information tab (Figure 8-46) allows you to
enable SR-IOV on NIC adapter ports. When SR-IOV is enabled, multiple VFs can be
created on a NIC PF for an adapter port. These VF's are assigned by virtual operating
systems such as Microsoft Hyper-V and Linux KVM to virtual machines (VMs). Each
VM can be assigned one or more VFs by the guest operating system running on the
VM. To the guest operating system, the VF is an independent NIC function with its
own MAC address and is available for network I/O.
The discovery-tree displays the VFs running on the discovered PFs. It also shows the
selected VFs MAC Address, VLAN ID, Link Status and Transmit Rate.
To enable or disable SR-IOV:
1. Select Host view.
2. Select a NIC port in the discovery-tree.
3. Select the Port Information tab.
4. Check or uncheck Enable SR-IOV.
