I’ve never been a huge fan of agents in the Service Console. Too many times I’ve seen hosts fail because of an agent that had a memory leak etc. Now it seems that running the HP IM agents causes your ESX 3.5 U2 to become unavailable after a certain amount of time. The errors that appear: 0 Z root 8536 [...]

About a month ago I got an email about problems with upgrading VMware tools on a Linux VM. When upgrading VMware tools all modifications done in /etc/fstab after the VMware tools section would be deleted. I never got the chance to actually test it myself but now a KB article popped up and confirmed the bug. Apparently the engineers are [...]

I get a lot of questions about ESXi and SSH. Most people manage to connect to their ESXi but don’t know what to do next because there’s no actual Service Console there. Well the answer is short and simple: vim-cmd. A couple examples of stuff you can do with vim-cmd: enter maintenance mode: vim-cmd /hostsvc/maintenance_mode_enter List all registered vm’s: vim-cmd [...]

The error message that appears: This product has [...]

So let’s start with a little history, back in the days “pre 3.5 U2″ one could configure a cluster on multiple IP subnets without facing any problems, but this could [...]

I’ve been asking around why the default isolation response has been changed from “power off” to “leave powered on”. It seems that this is done because a lot of customers had VM’s being powered off unnecessary. This happened because the service console or physical switches weren’t setup redundant and thus caused HA to kick in. In other words, for those [...]

How about backing up that dreadful application/server that you couldn’t or did not wanted to virtualize to your ESX environment? It could be useful to have a copy of a server that for whatever reason you did not virtualize. The new VMware Converter plugin for VirtualCenter gives you this option. You can create a reoccurring schedule for a p2v, you [...]
