Run automated server preparation

Run the automated server preparation script to prepare the TAS servers. The process runs in the background and takes several minutes to complete.

Before you begin

Customize inventory file
If you set users_deploy to false, make sure you have created the TAS groups and users
Make sure:
- You have root-user privileges
- The /media/Verint is still mounted
- The RPM ISO file is located in /opt/app/TAS_DRG

Procedure

Enable password-less root access for SSH to all TAS servers in your deployment, including the TAS Management server:
1. Log in as root:
  Copy
```
ssh root@<management_server_fqdn>
```
2. Generate the key:
  Copy
```
ssh-keygen -t rsa
```
3. In answer to the prompts, click Enter, as required.
4. Copy the key to the TAS Management server and to all the other TAS servers, using the target's server's FQDN.
  Copy
```
ssh-copy-id root@<target_server_fqdn>
```
  where:
  - <target_server_fqdn> is the FQDN of the TAS server to which you are copying the key.
5. Verify that SSH login to all TAS servers does not require any manual intervention or prompts.
Go to /opt/app/TAS_DRG:
Copy
```
cd /opt/app/TAS_DRG
```
Set permissions for the TA automated server preparation script:
Copy
```
chmod 744 DRG_setup.sh
```
Run automated server preparation as root user:
Copy
```
./DRG_setup.sh
```
When prompted, do the following:
1. To start the automated preparation, enter 1.
2. Enter the absolute path and name of the inventory file in /opt/app/production_inventories/<L_level_inventory>
  
  where:
  - <L_level_inventory> is the inventory file that matches your site deployment, for example, L1_NHA.
Monitor progress through the log generated in /tmp/Ansible_log_DRG_Setup_$DATE.log.
Make sure that 'PLAY RECAP' 'failed=0' is displayed on completion.
