Programatically extending the size of a Nutanix Disk with PowerShell and the v2 API
Intro
Often what you provision, isn’t sufficient for what you need a few months down the track.
Let’s say for example, you have deployed a Citrix Machine Creation Services (MCS) persistent Catalog with an 80 GiB fixed OS disk. Or maybe you deployed a nonpersistent Catalog and you decided to add an additional data disk. Maybe you even used Mr Kees Baggermans script to do so.
If you need to extend the disk capacity on these drives in a programmatic fashion, my preferred meethod on Nutanix infrastructure is via the API.
Here is a small PowerShell script, to help you expand existing disks for one or many machines, using the Prism Element V2 API. Simply specify a list of machines as known to Prism Element, a device bus (typically SCSI so it’s the default), a Device Index of the disk (0, 1, 2 for example) and the capacity you want to add in GB. Run it in whatif mode for planning output.
Job done.
The script is also linked in the usual Script Index portion of this site.
