So some interesting stuff has fallen out of the investigation we’ve done regarding how VMware High Availability handled five of our hosts falling off the network last week. In speaking with VMware’s support staff I’ve learned a few things to keep in mind when planning architecture, as well as how to respond to something like [...]
So we ran into this last night and are trying to work through why things happened the way they did – which is to say, why we had some support personnel on the phone who said “it shouldn’t do that.” The long and short of what a split-brain scenario is this: You have two hosts [...]
I’ll have to wait for the paperwork to come through in a bit, but I nailed my VCP410 exam this morning. Ah, the load off my chest at the moment… – mike
This little tidbit from The Lone Sysadmin saved our bacon this morning: if you’re finding it impossible to migrate a VM off of a host because of a stuck VMTools installation process, there’s a quick way to kill this process off via the command line to get things moving along.

If you end up using VMware’s VI Client to connect to multiple vCenter servers or ESX/ESXi hosts, you might find yourself a little annoyed at how many saved connections show up when you go to launch a new connection.

Here’s a case that’s justified for some [...]
So, on the heels of my post pointing out some tips on ways to increase the chances of successful physical-to-virtual conversions using VMWare’s Converter, you’ve decided to take the plunge and get rid of all those PowerEdge 2600′s you’ve got lying around. Good for you! You’ve successfully finished a clone of your server’s physical hard [...]
One of the tasks I’ve been working on for the past two months has been the conversion of a large number of physical servers to virtual machines using VMWare’s Converter 4.0. Once again, VMWare offers up a free product to get you sucked into it’s technology. I’ve used other P2V tools in the past, some [...]
I’ve found that two things get in the way of updating this site: skiing and starting a new job. I mean, being married and having a very active dog and wife and it being prime motorbike weather doesn’t usually put as much of a crimp on at least posting some new pics of the most [...]
