Before upgrading my Virtual Center 2.5 server to vCenter Server 4.0, I decided to temporarily disable HA and DRS. This is just a precaution taken to avoid waiting for cluster reconfigurations right after the upgrade. Because I hate doing things more than once by hand, I used PowerCLI for this.

Everybody backups their environment, but how many do actually test if the backup can be restored? When you do, you know how time consuming this process is and even when you do a test restore, you are actually only testing that particular backup. You can’t possibly test every backup in your environment.

I ran into an issue with a vCenter database recently, where I couldn’t see historical performance data anymore in the past week-, month- and year-view. When investigating it, it turned out that I couldn’t see any performance statistics older than 24hrs. I also took a look at the database and it turned out that the [...]

This is a follow up on a post I did a couple of weeks ago to create a mapping table between Windows- and VMware hard disks. In another previous post PowerCLI: Get WMI info from isolated guests, I showed you how to get WMI info from a guest without using the guest’s network. I used this [...]

A few weeks back I posted an article on matching Windows and VMware disks. Unfortunately this would work only if you could remotely query WMI information from that VM. If you have any VM that’s isolated or behind a firewall, you are out of luck. This bothered me, so I started looking for a uniform [...]

I just noticed that VMware released a couple of critical ESX3.5 fixes on December 29th, shortly after releasing ESX3.5 Update5 on December 3rd. Wading through the patch details I stumbled upon some severe issues addressed by the ESX350-200912401-BG patch. I quote some issues that caught my eye: 

ESX hosts might get disconnected from VirtualCenter Server. This issue [...]

In case you didn’t noticed already, Eric Siebert  from vsphere-land has proclaimed a new top bloggers election. Blogging takes a lot of work, and most of us do this on top of our day jobs and hence don’t get paid for it. So I’m honoured to be a nominee alongside world’s greatest virtualization bloggers.
