How to use validation tool

Run the validation tool from an OpenShift administrator shell after configuring the Multus NetworkAttachmentDefinitions and installing the Fusion Data Foundation operator, but before installing a Fusion Data Foundation StorageCluster.

For example:
```
oc rsh <rook-ceph-operator-pod-name>
```

The tool provides extensive help text. When you run the tool, you get the most up-to-date version of the tool.

```

What to do next

The validation tool supports a configuration file that allows configuring the number of test daemons on different types of nodes.
