VI Toolkit Advanced Script: Set-MultipathPolicy

Quick Tip: Check out my script for setting the multipath policy on a lun.

I am planning to write an elaborate post on unleashing the complete power of the Virtual Center API using PowerShell soon! Stay Tuned!

function Set-MultipathPolicy

{

param([string]$VMHost,[string]$lunId,[string]$PolicyName)

# Created by Hugo Peeters, JUNE 2008

# Description: Sets the multipath policy for a specified LUN

# EXAMPLE: Set-MultipathPolicy -VMHost “ESX1.example.com” -lunId “vmhba1:0:102″ -PolicyName “mru”

# Possible values for PolicyName: fixed, mru, rr

# Create filter for selecting the ESX host

$nvc = New-Object System.Collections.Specialized.NameValueCollection

$nvc.Add(“Name”,$VMHost)

# Link to host system

$HostSystem = Get-EntityView -ViewType HostSystem -Filter $nvc

# Link to host storage system

$HostStorageSystem = Get-View -MoRef $HostSystem.ConfigManager.StorageSystem

# create object for input to method

$policy = New-Object Vmware.Vim.HostMultipathInfoLogicalUnitPolicy

# set object properties

$policy.policy = $PolicyName

# Execute method

$HostStorageSystem.SetMultiPathLunPolicy($lunId,$policy)

}
