This script will add VLANs to an existing standard switch on a host.
Information needed:
$esxhost - Name of host
$vswitch - Name of existing standard switch
$vlanlist - List of all the VLANs you want to add to the switch
This will configure multipath to round robin and IOPS to 1 on all disks in a cluster based upon the vendor type.
This script is configured for 3par LUNs. Change $vendor for other storage types/vendors.
