Lister les différents volumes (LUNs) qui ne sont pas en mode MultipathPolicy RoundRobin :

Get-VMHost esx1.domain.local | Get-ScsiLun -LunType disk | Where {$_.MultipathPolicy -notlike "RoundRobin"}

Lister les différents volumes (LUNs) qui sont en mode MultipathPolicy RoundRobin :

Get-VMHost esx1.domain.local | Get-ScsiLun -LunType disk | Where {$_.MultipathPolicy -like "RoundRobin"}

Changer la stratégie Multipath en mode RoundRobin pour un ESXi :

Get-Vmhost esx1.domain.local | Get-Scsilun -LunType disk | Where {$_.MultipathPolicy -notlike "RoundRobin"} | Where {$_.CapacityGB -ge 200} | Set-Scsilun -MultiPathPolicy RoundRobin

Changer la stratégie Multipath en mode RoundRobin pour tous les ESXi :

Get-Vmhost | Get-Scsilun -LunType disk | Where {$_.MultipathPolicy -notlike "RoundRobin"} | Where {$_.CapacityGB -ge 200} | Set-Scsilun -MultiPathPolicy RoundRobin

Lister les différents volumes (LUNs) et vérifier le modèle et le type de matériel :

Get-VMHost esx1.domain.local | Get-ScsiLun -LunType disk | fl -show CanonicalName, Vendor, CapacityMB, Model, LunType

Avoir la correspondance entre les CanonicalName et le nom de la LUN :

Get-Datastore |
Where-Object {$_.ExtensionData.Info.GetType().Name -eq "VmfsDatastoreInfo"} |
ForEach-Object {
  if ($_)
  {
    $Datastore = $_
