The New-Datastore cmdlet allows you to easily create VMFS datastores on a free LUN or local disk. But what if you want to create a VMFS datastore on that free partition you have left on a LUN or on a local disk ? These free GBs could come in handy and it’s a shame letting them go to waste. Unfortunately, the New-Datastore cmdlet doesn’t have an option (yet) to handle “free space” partitions.
Exactly such a question was raised by Alasdair in his thread new-datastore on ESX4i Installable local disk in the PowerCLI Community recently.

Another idea triggered by a post in the PowerCLI Community. Lars wanted to know where his VMs had been running in the past.
Since vSphere doesn’t maintain any historical data with the guests themselves, we have to fall back on the Tasks and Events to create such a report. The basic algorithm to query the tasks, and their related events, is already published in Events – Part 3 : Auditing VM device changes. But to get a historical record of the servers where your guests have been hosted requires a bit more logic in the script.
I received an interesting comment on my Events – Part 7 : Working with extended events – Update Manager post from Suresh. He wanted to know if it was possible to create a similar report with the vCenter Update Manager PowerCLI cmdlets as you can get with the esxupdate query command.

As I already mentioned in my previous post, Events – Part 6 : Working with extended events – Converter, another
add-on that produces extended events, is the Update Manager.
With the recent introduction of the vCenter Update Manager PowerCLI snapin, it is now fairly easy to automate all aspects of patch and update management in your vSphere environment. And with the help of the extended events produced by Update Manager, you can easily produce reports. This post shows one way of doing this.

In a previous post, called Events, Dear Boy, Events – Part 2, I mentioned that some tools/add-ons use a special event type called ExtendedEvent. Two classic examples are the Converter and the Update Manager. If you want to compile a report for any these tools it’s important to understand what is available in the extended events they produce.
If you want to know if there are any other tools/add-ons in your vSphere environment that produce extended events, then you can use the first script from the Events, Dear Boy, Events – Part 2 post to get a complete list of all available extended events.
In this post I’ll show how to use the Converter extended events.
