To find out single or no active paths from iSCSI LUNs to the filer

One of good thing the following script to do is to list iSCSI LUN's that have either single or no active paths to the filer. Can somebody please let me know what OnTap commands would show the same thing, preferrably, or Powershell commands  Thanks!

The script is for scanning any potentional issue before upgrade.
