Powershell – Snapshot VM on NUTANIX AHV with call API

Un petit script en Powershell permettant de faire un appel à l’API Nutanix AHV pour généré un snapshot d’une VM.

Pour l’un de mes clients, j’ai dut gérer la création de snapshots de VMs planifié depuis un ordonnanceur. Les actions sont réalisés via Powershell qui se connecte à l’API AHV.

Le script peut aussi être téléchargé en cliquant sur le lien ci-dessous :

[Parameter(Mandatory=$true)][string]$VMTargetAction,

[Parameter(Mandatory=$false)][string]$SnapshotName="$(Get-Date -Format "yyyyMMdd-HHmmss")_RunByAPI"
)

if(!$(Test-Path -path $logPath)){New-Item -Path $logPath -ItemType "directory" | out-null}
