Unfortunately the normal command to set this($vHcli.storage.nmp.satp.set($true,"VMW_PSP_RR","VMW_SATP_DEFAULT_AA")) has a bug in PowerCLI where the host will not retain these settings after a reboot. Big thanks to vitalibaruh and LucD for providing a great workaround! This will configure Default SATP PSPs for all hosts in your vCenter!
#Setting Default Path Selection Policies for all Hosts
$vHs = Get-VMHost
ForEach($vH in $vHs){
#Getting ESX CLI for each Host
$vHcli = Get-EsxCli -VMHost $vH
#Does it have the correct PSP for IBM SVC
$SVC = $vHcli.storage.nmp.satp.list() | Where {$_.Name -eq "VMW_SATP_SVC" -and $_.DefaultPSP -ne "VMW_PSP_RR"} | Select @{N="Cluster";E={$vH.Parent.Name}},@{N="VMHost";E={$vH.Name}},DefaultPSP,Name
If($SVC.Name -eq "VMW_SATP_SVC" -and $SVC.DefaultPSP -ne "VMW_PSP_RR"){
Write-Host "Configuring $vH SVC"
#Create a low level object that points to the satp namespace:
$LowLevel = $vHcli.TypeManager.CreateDynamicManagedObject( $vHcli.storage.nmp.satp.id )
#Create a hashtable holding parameter values. Note that here we do not specify value for boot parameter:
$Params = @{"DefaultPSP" = "VMW_PSP_RR"; satp = "VMW_SATP_SVC"}
#Invoke set operation on the $LowLevel object:
$LowLevel.InvokeOperation("set",$Params)
}
#Does it have the correct PSP for Defaults
$DAA = $vHcli.storage.nmp.satp.list() | Where {$_.Name -eq "VMW_SATP_DEFAULT_AA" -and $_.DefaultPSP -ne "VMW_PSP_RR"} | Select @{N="Cluster";E={$vH.Parent.Name}},@{N="VMHost";E={$vH.Name}},DefaultPSP,Name
