The Doctor is: IN

Many of us in IT read a lot of whitepapers, blogposts, how-to articles and view numerous Podcasts or training video’s to learn all the details about new products or features. Still, I don’t always get some of the details or can’t find the info I need. Meeting people at VMUGs or VMworld gives me the changes to ask for those last missing piece of information. But what if you don’t have that chance?

The Doctor is IN

When I blog about stuff I’m sometimes surprised about the comments I get and about how more people than I thought were struggling with the same questions. In responds to the comments I have been able to help quite a number of readers of my blog by e-mail and lately I did a few Google Plus Hangout sessions to help in an even better way. And that is when I came up with the following idea: Why not do a video-chat help session? [Read more…]

AutoDeploy Failed to convert ItemList

When working with VMware vSphere AutoDeploy and creating or editing rules I sometimes get the following error when running a Get-DeployRule: “Failed to convert ItemList to VI Object: System.NullReferenceException: Object reference not set to an instance of an object” (See screenshot).

Often I also have one or more rules not working correctly then. Turns out that an unsupported character had been using when creating the rule. This sometimes happens when using your comma’s or spaces incorrectly. Then the command seems to work but the properties end up in the incorrect fields. [Read more…]

VKernel interview at Dutch VMUG

At the Dutch VMUG on December 9th, 2011 I was asked to do a little interview with Alex Rosemblat from VKernel. We spoke about the presentation I did at the VMUG in which I talked about my VMware vSphere Health Check. See the pages about the Health Check in the top menu bar.

Also check out VKernel’s latest release of VKernel vOperations Suite which offers a great way to do performance and capacity management of your vSphere and Hyper-V environment.

VMware vSphere Health Check

At the Dutch VMUG event 2011 I gave a presentation on how to check your VMware environment to make sure it is healthy. When creating the presentation I had a lot of doubts because I was afraid everyone would think these points were very obvious. But on the other hand, when visiting customers and doing these health checks for them, I found a lot of those “obvious” issues in their environment. I decided to stick to my plan and test the audience and it turned out they were very happy with my presentation and I saw a lot of people in the audience taking notes. The replies afterwards also showed that for many people there were a lot of eye-openers in this presentation. I therefore decided to convert the power point presentation into this blogpost and hope my readers find it a valuable health check.

In the top menu bar of this blog you’ll find the “Health Check” section. There you can find the various pages that together give you a complete health check.

Updating your ESXi host using VMware vSphere 5 Auto deploy

In my previous post on VMware vSphere5 Auto deploy I explained how to setup an auto deploy environment. This is great for initial setup and to deploy your hosts, but what when an update is released by VMware? The easiest thing is to just delete the deploy rules and recreate them which is ok for a small environment but not in a large environment. In this post I will show you how to adjust your existing rules. [Read more…]
