Change storage pathing in ESX5

In ESX4 I used a script to cycle through the available datastore paths and set the connection type to round robin. In ESX5 it changed a bit, so this is the updated script

param([string] $server = $(throw "Server param required")

 ,$user,$pass)



if ($user -eq $null)

 {connect-viserver $server}

else

 {connect-viserver $server -User $user -Password $pass}



$esxcli = Get-EsxCli

$esxcli.storage.nmp.path.list() | group-Object -Property Device | where {$_.count -ge 4} |  %{ $esxcli.storage.nmp.device.set($null, $_.Name, "VMW_PSP_RR")}

$esxcli.storage.nmp.satp.set($null, "VMW_PSP_RR", "VMW_SATP_ALUA_CX")



disconnect-viserver $server -confirm:$false
