Multipathing

[wamatha]

Hi

Is there a PowerCLI script out there that would change multipathing on an ESXi host to Round Robin, but leave the RDM alone.

The one I saw on these forums changes all the datastores to Round Robin including RDM's. I need RDM to remain on fixed multi pathing

Thank you

we use the following script

$Mypolicy = "rr"
 
Get-Datastore | where {$_.Type -eq "VMFS"} | %{(Get-View $_.ID).Info.Vmfs.Extent[0].DiskName} |%{
  $diskname = $_
  Get-VMHost | %{Get-View (Get-View $_.ID).configmanager.storageSystem} | %{
    $mpathpolicy = New-Object vmware.vim.HostMultipathInfoLogicalUnitPolicy
    $mpathpolicy.policy = $Mypolicy
    $_.SetMultipathLunPolicy($diskname,$mpathpolicy)
  }
}
