Virtual SAN: Suppress ‘Datastore Usage on Disk’ Alarm

KB ID 0001527 Problem While deploying a HPE StoreVirtual VSA this week. We noticed all the local Datastore were showing an ‘Alarm’. If you are unfamiliar with Virtual SANs, then you give all the LOCAL Storage to them, which then gets ‘aggregated’ and provided back to the host(s) as fault tolerant clustered storage, like so; Which is great, but the VMware hosts just see that their LOCAL Datastore(s) are full,...

VMware Fusion on macOS Mojave: No Mouse or Keyboard

KB ID 0001523 Problem While building my new MacBook, I installed VMWare Fusion, (I always run a Windows VM, in case I have to do something on Windows).

Manually Extracting VMware Tools Drivers

KB ID 0001518 Problem If you want to get hold of the actual drivers from VMware tools, e.g. to have them in a machine that you will be deploying into VMware ESX/Workstation etc, then this is how to do it. Solution I’m using WinSCP to connect to one of my ESXi servers, (it’s free, and just works!) From the root directory locate vminages and open that. Tools-isoimages, (this might seem long-winded, but if you keep an eye on...
