So I have 4 separate Datacenters in vCenter with a total of 12 ESXi hosts:
DC1: Host 1
DC2: Host 2
DC3: Hosts 3 through 4
DC4: Hosts 5 through 12
We have been using our core switch in the primary DC (DC4) as our NTP server, but more and more recently have been finding drift. I would like to switch the NTP servers on each host to a public facing NTP server (pool.ntp.org, most.gov etc) for a little redundancy.
What’s your opinion on doing this the most efficient way possible? I have a script to check the times through powercli, and then was planning on manually setting the time on each one to correct time, and then stop/starting NTP with the new NTP server configs one by one.
