Troubleshoot a VMs operating system disk
This script mounts the operating system disk of a failed or problematic virtual machine as a data disk to a second virtual machine. This can be useful when troubleshooting disk issues or recovering data.
To run this sample, install the latest version of the Azure CLI. To start, run az login to create a connection with Azure.
Samples for the Azure CLI are written for the bash shell. To run this sample in Windows PowerShell or Command Prompt, you may need to change
elements of the script.
If you don't have an Azure subscription, create a free account before you begin.
