Often within the VMware App Volumes Manager (AVM), Writable Volumes will show up as Status – Orphaned. Let’s take a look at the following topics:
- What is Orphaned Writable Volumes?
- Script to delete them from the App Volumes Managers
What is Orphaned Writable Volumes?
App Volumes Manager is integrated with Microsoft Active Directory (AD), and it’s in continuous synchronization. Whenever an end-user account gets disabled into the AD during the next sync activity of App Volumes Manager, it will mark the writable volumes with Writable Status = Orphaned.
Now in the ideal world, these accounts have been disabled and should be okay to delete? Maybe, if you don’t have the obligation of data retention, then you are ready to delete them. If you need to retain them, keep them as-is for compliance purposes.
Script to delete them for App Volumes Manager
Before we talk about the script, the deletion is very straightforward within the App Volumes Manager. Select the volumes with Status = Orphaned and select the Delete button. However, when you have to do the same against multiple POD, which becomes challenging, and as always, if it’s not automated, there is the scope of human error.
Pre-requisites
- You need the App Volumes Manager URL
- You need the username and password of the App Volumes Manager
- You need to enter y/Y to proceed further with the deletion
- The script was tested on PowerShell V5.x with App Volumes Manager version 2.18.10 (The logic will be the same however, the API call for App Volumes 4.x will be different)

Observations
- When you run the script, it will identify all the end-users with Status = Orphaned. If you like, you can copy and paste the output in an editior (Notepad++) to verify the output.
- Once you press y/Y it will go ahead and delete the Orphaned writable volumes.
I hope you will find this script useful to bulk delete orphaned Writable Volumes in App Volumes Manager. A small request if you further enhance the script or make it more creative, I hope you can share it back with me?
Thanks,
