How to Add an InfiniBand Virtual Function to a Root Domain

This procedure describes how to add an InfiniBand SR-IOV virtual function to a root domain.

Initiate a delayed reconfiguration.
```
primary# ldm start-reconf root-domain
```
Add one or more virtual functions to the root domain.
vf-name is the pseudonym name or the path name of the virtual function. The recommended practice is to use the pseudonym name. root-domain-name specifies the name of the root domain to which you add the virtual function.
```
primary# ldm add-io vf-name root-domain-name
```
Reboot the root domain.

Run one of the following commands:
- Reboot the non-primary root domain.
```
primary# ldm stop-domain -r root-domain-name
```
- Reboot the primary root domain.
```
primary# shutdown -i6 -g0 -y
```
