Configuring SR-IOV

Prerequisites

Ensure that the RHCOS servers are reachable from the NPS toolkit VM.
Ensure that the RHCOS cluster is up and running and all nodes must be in READY state.
Ensure that interface names provided in the sriov_profile must match the interface available in the worker nodes.
Ensure that the VIM is in REGISTERED state.
To check the state of the server, use the following nps command:
```
nps show --data servers --node <worker node ilo ip>
```
If this prerequisite is not satisfied, then NPS considers the server (worker node) as not ready to configure SR-IOV and it skips that server.

Procedure

Use the following NPS RHOCP command to configure SR-IOV on the RHOCP cluster:
```
nps deploy -s rhocp -a configure-sriov
```
Check the status of the operation using the following command:
```
nps show --data vim
```
Wait until the status is displayed as SRIOV_CONFIGURED or SRIOV_CONFIGURE_FAILED:
1. If the state is displayed as SRIOV_CONFIGURED, then SRIOV is successfully configured on the RHOCP cluster and the individual server vim state is updated as SRIOV_CONFIGURED.
2. If the state is displayed as SRIOV_CONFIGURED_FAILED, see SR-IOV configuration fails.
