Extend HIAB Disk Space on Azure

Purpose

This article describes how to extend the disk of a running HIAB on Azure.

Introduction

This article provides a comprehensive guide on how to extend the disk of a running HIAB on Azure. It details the necessary steps, including shutting down the virtual machine (VM), modifying the disk size, and restarting the VM. The process starts with shutting down the HIAB VM via the Serial Console, confirming the shutdown, and ensuring that the VM status reflects "Stopped." After that, users can access the Disks menu to adjust the disk size as needed and save the changes. Finally, the HIAB VM can be restarted, returning its status to "Running."
