In the vCenter Client, since vSphere 4, you can find a Storage Views tab on several of the VI containers. The data in these Storage Views is collected and provided by the vCenter Storage Monitoring plug-in.
Have a look at David Davis‘s post, called Using VMware vSphere Storage Views, for more information on what you can do with the Storage Views.
Some time ago I got a question from Andrew how the Multipathing Status presented in the Storage Views could be detected and reported upon by a PowerCLI script. What looked rather simple at first, turned out to be a bit more difficult than I anticipated.

When you’re using ThinApp to package your software packages you are bound to end up with a huge repository after some time. Of course you have documented each ThinApp package you made, but sometimes you will need to produce a quick-and-dirty report. Then it’s handy to fire up a PowerShell script, instead of reading through all the packaging documentation.
With the help of the ThinApp SDK it’s quite easy to produce such a report.
When you are running multi-node vSphere clusters, you probably already had the experience that one or more of your LUNs were not visible on all nodes. Now you can try to find out which LUN is missing on which node the hard way through the vSphere client. Or you can use the force of PowerCLI and run a script that will report all this in a handy spreadsheet.
To make the script as flexible as possible it should be able to handle any n-node cluster. And as you some of you might know, the Export-CSV cmdlet has some problems with variable length rows. Luckily there is a handy solution I already used in my yadr – A vDisk reporter post.

I know there are already numerous scripts to report on virtual hard disks and most of them without a doubt much better then what I came up with for this post.
The reason I started with this script was a question in the PowerCLI Community from Alan in his Thin Provisioned Disks post. He wanted to know if you could get the provisioned and the allocated disk size for a thin provisioned virtual disk.
