    Hi Viren,

    AFAIK, you will need AD DS in each site to recover from a site failure for authentication and I believe witness disk is a mandatory resource during the failover process as you are trying to recover the services via the Cluster resource in another site. Not sure which link you have used as I cannot see in the post, check this page and detailed design requirements for HCI DR process

    Hope this helps.
