Hi Ravi -  Good News! I was able to locate someone who happen to have a document that talks to using PowerShell with VPLEX using REST API, titled "PowerShell Scripting With VPlex Using the REST API-2016_V1.pdf". It is now located on the Dell EMC Community Network (DECN) page. Here is the link to it, [URL]  Hope this helps.
Hi,  I am new to power-shell and I am trying to connect the VPLEX using the REST API through powershell script but didn't succeed . Doesn't anyone has connection script for power shell so I can build rest of the  script on it .  Ravi
