What-If in VMware vRealize Operations for VxRail/vSAN Host adds to Cluster

Posted by

One of the things I enjoy about VMWare vRealize Operations is the ability to add or remove HCI nodes in a cluster.  I don’t know if I have been fortunate or unfortunate in my career but I have had to do a lot of VxRail/vSAN Ready Node adds.  On some occasions I have been requested to remove hosts from one cluster and build a net new cluster.  With this comes the question of is it possible.  I hope the below step by step on how to pan for adding hosts is useful.

Summary:
It is a pretty quick and seamless process to see if adding X number of hosts will meet your growth requirements.  Bonus is that you can take screenshots and put them into a report.  As always, I hope y’all found this to be useful.
