NTP configuration on multiple ESXi hosts via PowerCLI

As you might know, keeping our ESXi hosts’ date and time accurate is very critical. To prevent having an inaccurate time configuration we can use the NTP server in our environment.
A few days ago, I faced a question about NTP configuration in the vSphere environment and how to set NTP configuration on many ESXi hosts. Hence, I decided to use the PowerCLI commands to configure NTP configuration most easily with an example.

Kindly find the commands have been used in my example:

Connect-VIServer vCenter_Server_Address
Get-VMHost | Add-VMHostNtpServer ntp.virtual-mir.com
Get-VMHost | Get-VMHostFirewallException | where {$_.Name -eq “NTP client”} | Set-VMHostFirewallException -Enabled:$true
Get-VMHost | Get-VmHostService | Where-Object {$_.key -eq “ntpd”} | Start-VMHostService
Get-VMhost | Get-VmHostService | Where-Object {$_.key -eq “ntpd”} | Set-VMHostService -policy “automatic”

I’m sure if you are a GUI person, switching to PowerCLI might be a hard transition but once you used to script, you will never go back to GUI, and learning new things is always fun, so let’s try out.
