In previous post, We validated the base NSX-T env which is setup to perform Disaster Recovery of NSX-T. Here is the link to the previous post.
NSX-T 3.1 – Backup & Restore_Production DR Experience – Part1
There are couple of validation steps from DR point of view. Let’s start with the DR Validation Phase. I have bullet point in excel sheet. Will discuss them one by one with screen captures.
We need to make sure that the publish fqdn is set to ‘true’ in all nsx-t managers using the API call.
Here is the Get API call followed by PUT for all 3 NSX-T managers…
Before we go there let’s have a look at the backup details.
Note that the Appliance FQDN or IP lists an IP address of the appliance.
Let’s go back to the API call and run it. I am using postman utility for API calls.
Paste the above command, change the Authorization type to ‘Basic Auth’, enter the credentials and send. You might get SSL error if it is not disabled already.
Click on Settings and disable SSL verification here…
and send the call again.
Note that the ‘publish_fqdns’ value is false. We need change this to ‘true’
Change GET to PUT, copy 4 lines, Click on ‘Body’ change the radio button to ‘raw’ and select JSON from the drop down box at the end.
Paste copied 4 lines and change the value to ‘true’ and send it again.
Make sure to see the status as 200 OK.
Use the GET command again to verify…
Make sure that you see this value to ‘true’ on all 3 nsx-t managers.
Let’s go back to NSX-T and run the backup again. Note that the ‘Appliance FQDN’ now lists the FQDN instead of an IP address.
All good till here. Move to next step in the excel sheet.
Next step is to verify that all transport nodes in the env using FQDN instead of an IP address.
Run ‘get controller’ command on each edge node. Note that the “Controller FQDN” lists the actual FQDN instead of an IP.
All good here. Move to next action item…
Change the TTL value from 1 hr to 5 mins of all NSX-T managers in DNS records properties.
We have completed all validation steps for DR test. We now move to actual DR test in the next part of this blog series. Thank You.
