Verifying the post cloud deployment

Procedure

Log in to the undercloud VM as "stack" user. The IP of Undercloud VM and password for the stack user is available in the Input JSON file or can be obtained from NPSVM by following these steps:
1. Log in to the NPSVM.
2. Export the environment variables.
```
export API_IP=<NPS Toolkit VM OAM/Customer Network IP address>
export NPSADMIN=<user name of admin mentioned in the nps_secret.yaml file>
export NPSPASSWD=<password of admin user mentioned in the nps_secret.yaml file>
export TOPOLOGY_NAME=<value of the field "topology_name" in the input.json file>
export VIM_TYPE=<VIM platform type like RHOCP/RHOCP/VMWARE>
```
3. Execute the following command in the NPSVM to get the Undercloud details:
```
nps show --data vim --node undercloud
```
  Look for the field named "stack_pw" for password of "stack" user. For IP of undercloud VM, look for the field named "oam_ip".
Check nova services by running the following command in the Undercloud VM:
```
source overcloudrc
openstack compute service list
```
The state of services must display as "up".

Check the status of cluster services by executing the following commands:

NOTE:

The VIP address is mentioned in the field "OS_AUTH_URL" of the overcloudrc file in the Undercloud VM.

source stackrc
ssh heat-admin@<VIP IP address>
sudo pcs cluster status --all

The status of cluster nodes must display as "Online".

[heat-admin@overcloud-controller-0 ~]$ sudo pcs cluster status --all
