How to Modify Fibre Channel SR-IOV Virtual Function Properties

Identify the physical function device.
```
primary# ldm list-io
```
Note that the name of the physical function includes the location information for the PCIe SR-IOV card or on-board device.
Modify a virtual function property.
```
ldm set-io [bw-percent=value] [port-wwn=value node-wwn=value] pf-name
```
Unlike the bw-percent property value, which you can dynamically change at any time, you can dynamically modify the port-wwn and node-wwn property values only when the virtual function is not assigned to a domain.

Example 8-24 Modifying Fibre Channel SR-IOV Virtual Function Properties

This example modifies the properties of the specified virtual function, /SYS/MB/PCIE7/IOVFC.PF0.VF0, to specify the bandwidth percentage and the port and node WWN values.

primary# ldm set-io port-wwn=10:00:00:14:4f:fc:f4:7c \
node-wwn=20:00:00:14:4f:fc:f4:7c bw-percent=25 /SYS/MB/PCIE7/IOVFC.PF0.VF0
