Install the Nutanix Powershell Cmdlets from the Prism console on to a system that can access the cluster. And then the script is fairly straight forward.

  1. Connect to cluster
  2. Power on first VM
  3. Wait for a set number for minutes or use a ping command to determine network status
  4. Power on second VM
  5. Repeat steps 3 and 4

Below is some fairly crude code that should work.

[cmdletbinding]
param(
    [Parameter(mandatory=$true)][String[]]$VMNames
)

$ntnxpsLoaded = Get-PSSnapin -Name NutanixCmdletsPSSnapin -ErrorAction SilentlyContinue | %($_.Name)
if($ntnxpsLoaded -eq $null) {
    Add-PSSnapin -Name NutanixCmdletsPSSnapin
}
Connect-NTNXCluster -Server <DNS/IP> -UserName <acct> -Password (Get-Credential).Password
foreach ($VM in $VMNames) {
    Set-NTNXVMPowerOn -vmid (Get-NTNXVM -SearchString $VM).vmid
    Start-Sleep -Seconds 300
}

This could be accomplished through a powershell script with the Nutanix Cmdlets or with something that accesses the REST API of Prism.
