Yesterday evening I witnessed a weird phenomenon. We had to bring down a complete environment to move a 19″ rack to a different location. We switched the SAN on, waited a couple of minutes and switched the ESX hosts on. When the ESX hosts finished booting we booted the VirtualCenter. Everything looked normal in the […]

Today I combined a couple of Powershell scripts which as a result gives a nice html formatted file with a table. This table contains all VM’s with their VMware Tools status and version. I’ve uploaded the script here. The outcome looks like the following:

Today I noticed the following error at a customer site when I wanted to install the new patch bundle, ”Metadata for patch missing”. After a close inspection I noticed VirtualCenter was installed with a different http port number. For VMware Update Manager to work you will have to open up the firewall manually:
 esxcfg-firewall -o 81,tcp,out,UpdateManager
(Change the port number, in […]

VMware seems to have ditched the product name “3i” and silently introduced “ESXi”. I noticed it when the download page was updated today. But you can also read it on the “product section” of the VMware website. I think this is a better name instead of differentiation in versions, keeping the versions alligned and changing […]

Rob de Veij created a cool tool for checking the status of VMware Tools and easily upgrading to the latest version of the tools by just selecting the appropriate VM.
RVTools is a small .NET 2.0 application which uses the VI SDK to display the version of the installed VMware tools.It […]

Just stumbled upon this cool article about mounting your VI inventory as a drive via Powershell:

for example,

When prompted, provide the administrator’s username and password to authenticate access on the server.
