    Hi,

    I'm looking a way to automatically change the multipath setting of all RDM disks (of all VMs)

    Do you know how to acheive this.

    You could try this

    # Get all RDMs
$RDMs = Get-VM | Get-HardDisk | where{$_.DiskType -like "Raw*"} | %{$_.ScsiCanonicalName}

# Set multipath to fixed (can also be RoundRobin or MostRecentlyUsed
Get-VMHost | Get-ScsiLun | where {$RDMS -contains $_.CanonicalName} | Set-ScsiLun -MultipathPolicy "Fixed"
