About this task

To modify the options or parameters of a cluster resource, use the following syntax:

 Resource: VirtualIP (type=IPaddr2 class=ocf provider=heartbeat)
  Attributes: ip=192.168.0.120 cidr_netmask=24

```
# pcs resource update VirtualIP ip=192.169.0.120
```

Verify the updated parameter values for the VirtualIP resource:
