I’ve been playing around with powershell yesterday. We needed to create over 100 VM’s and there’s no point in doing that all by hand. The customer provided us with a .csv file that contained specific info on these VM’s. It took me a while to figure out how to read the info.csv file and how to actually use it. But [...]

Last week the well known powershell guru Alan Renouf helped me out with a script for enabling virtualized MMU. This week I needed to set Disk.UseDeviceReset to “0″ on at least 60 hosts. (Check the link for more info on why!) No point in doing it all by hand when the VI Toolkit can help you out and set this [...]

Just noticed this pingback. The topic title “Balancing LUN paths on your ESX hosts with powershell” sounded promising so I headed over. Justin Emerson is the owner of the blog and he wrote a short but effective script that changes the active paths on your active/active SAN(FIXED). After watching this video that was posted by the VI Toolkit team, I [...]

So much have been added that it would be pointless to blog about all the changes, 32 new cmdlets and 25 new options for [...]

One of the most promising features in my opinion for the upcoming version of ESX definitely is “Host Profiles”. With host profiles you can ensure that each and every single ESX Host has been installed in the same way. But this feature isn’t available yet, and you would probably like to know if at least all hosts in a Cluster [...]

While doing a “mini-healthcheck” at a customer site I noticed a specific Datastore with less than 2% of free diskspace. After a bit of research an orphaned VMDK was found. Orphaned vmdk’s are virtual hard-disks that are not connected to a VM. Probably because they were removed from the inventory without deleting the files. You can easily find these orphaned [...]

Hugo posted a great script. It will compare configuration items between a given set of hosts. This can especially come in handy when you’ve got a huge amount of datastores, portgroups or a huge amount of ESX hosts for that matter. Hugo’s post contains a set of excellent examples. Just check his post for more details and the script, heres [...]
