Updating ESXi hosts using Update Manager
You may be aware of the recent WannaCry ransomware attack. I mean who wasn’t, right? Internally within our company this caused a bit of a stir around patching and making sure our environment is up to date. Something that is overlooked by a lot of support staff but can be devastating if not kept up to date. At a recent VMUG I attended Michael Armstrong (@m80arm) from VMware was given a presentation on NSX security and asked for a show of hands if anyone’s environment is 100% patched. The result… no hands from 50 attendees! Quite alarming. So let’s go through patching our ESXi hosts using update manager.
