export TOPOLOGY_NAME=<value of the field "topology_name" in the input.json file>
export VIM_TYPE=<VIM platform type like RHOSP/RHOCP/VMWARE>

Update the bond using the following NPS CLI command:

nps update-switch --switch1 <data_switch1_ip> --switch2 <data_switch2_ip>

Log in to any one of the overcloud controllers as heat-admin and run the following command to start the cluster service on all the controllers.
```
sudo pcs cluster start --all
```
Verify the status of the cluster service on the controller using the following command:
