In this article I will cover setting up your first two Global Managers and adding the local managers from your sites.
Log into the newly deployed Global Manager
System > Configuration > location Manager
Make Active
Provide the name of your Global Manager
Confirm the GM is active
SSH into the Global Manager
Run the #get certificate api thumbprint
Store this output somewhere
Repeat this for your NSX-T Global Manager in location 1 and location 2
Now it is time to deploy the standby Global Manager
Add standby
Enter the name of the new GM
Provide the FQDN of the standby GM
Admin username
Copy the standby site NSX-T GM thumbprint here
Then check compatibility
Confirm the managers
Next we need to add the onprem location for the first site – my example Dallas
Enter the name for the first site local manager
Provide the FQDN for the NSX-T manager for location 1
Copy the thumbprint for location 1 NSX-T manager
Click check compatibility
Ignore this error as it will go away when the LM syncs with the GM – takes around 5-15 minutes
Rinse and repeat to add in your second location – my example is FortWorth
Next we need to import objects to the GM
