I have been testing VSAN in my whitebox hosts of my home lab lately, as I consider migrating off the smattering of Synology and other datastores. My first mistake was using a spinning drive that apparently was already bad as I quickly got some permanent device loss errors after spinning up some VMs. I was concerned why I never got any actual VSAN alarms, and just randomly stumbled on the reason why via Reddit.
Turns out, vCenter does not contain any VSAN alarms that map to VOBs. This KB shows how to add a few of them, but Mister VSAN Rawlinson Rivera’s blog post shows a longer list that appears pretty comprehensive and also includes a bit of powershell code to add the alarms for a specific cluster. I could not get the code to copy/paste from the blog without characters getting all screwy so it took quite some time to clean up. Here on my git repo is a version of it that works as is.
