vSAN Unicast Agent List Issue

I had a few problems with my homelab last week after rebuilding one of the hosts in my vSAN cluster. I moved the ESXi install from an increasingly ancient USB drive to an internal SD card. That part was relatively painless. But when I tried to put the “new” host back into the vSAN cluster I ran into issues. It would just not rejoin. I initially thought I might have knocked a few cables in the change around but vmkpings on all vSAN interfaces checked out so time to run some cli commands. esxcli vsan cluster get This gave me...

Shutdown vSAN Cluster with Horizon Instant Clones

In previous versions of vSphere it has been necessary to run CLI commands or edit host config to remove parent VMs (for instant clones) before shutting down a cluster. This is not required in ESXi 6.7 so the process has become a little easier. Here is a bare bones process that I use to cleanly shut down then startup a vSAN cluster running instant clones (tested with Horizon 7.7/ESXi 6.7 u1). In this instance, the vCenter appliance is also running on the cluster so this will add some extra steps to the process. **I have also included a few powercli...
