rolling restart of vSphere 6.5 VCSA using powercli

[imompero]

Any one know if there is an particular way of restarting vcenter using powercli.  And then verifying it is up before moving on to the next vcenter?  I manage 6 vcenter environments andwith a thought to myself there has to be a better way then rebooting via the appliance web gui, pinging, testing, and repeat for the next one.

I know I can do it easily a "Restart-VM -VM $vcenternames -RunAsync -Confirm" But is there a smart way of doing this? Is there a way to put vcenter HA into maintenance mode using powercli? Is there a way to create a "until" vcenter 1 is up before moving on to vcenter 2?

First, not sure if there currently is a public API for VCSA HA. Investigating.

With the following you can restart all the VCSA to which you are connected (with Connect-VIServer).

The Connect-CisServer in the script doesn't use Credentials because I use the VICredentialDatastore.
Give this a try

# Make sure you are connected to all vCenters

foreach($vc in $global:DefaultVIServers){

   $cis = Connect-CisServer -Server $vc.Name

   $shutdown = Get-CisService -Name com.vmware.appliance.shutdown

   Write-Host "Rebooting VCSA $($vc.Name)"

   $shutdown.reboot(0,'Planned VCSA reboot')

   $sPing = @{

  ComputerName = $vc.Name

  Port = 443

  WarningAction = 'SilentlyContinue'

  }

   Write-Host "Waiting for reboot to start"

   while((Test-NetConnection @sPing).TcpTestSucceeded){

  sleep 5

  }

   Write-Host "Waiting for VCSA to come online"

   while(-not (Test-NetConnection @sPing).TcpTestSucceeded){

  sleep 5

  }

   Write-Host "VCSA $($vc.Name) started"

   $cis = Connect-CisServer -Server $vc.Name -ErrorAction SilentlyContinue

   while(-not $cis){

  sleep 5

   $cis = Connect-CisServer -Server $vc.Name -ErrorAction SilentlyContinue

  }

   $health = Get-CisService -Name com.vmware.appliance.health.system

   while($health.get() -ne 'green'){

  sleep 5

  }

   Write-Host "VCSA $($vc.Name) health status green"

}
