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...


vSphere 7 – ESXi upgrade

So having upgraded vCenter it’s time to do the hosts.  I’d normally use Update Manager for this – which has had an overhaul and is now Lifecycle Manager. One thing to call out here is that I ran a test prior to upgrading my hosts by installing the hypervisor onto a USB stick and booting from that to make sure there were no hardware issues.  I used remote management to attach the iso to the host and plugged in a USB key to install vSphere 7 onto.  If you don’t have remote management the same can be achieved by creating...


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...
