Use these steps to increase the disk space on the virtual machine you are using.
Note
Performing this process is especially applicable for the 4502 model, since you cannot increase the disk size when you create the virtual machine.
To increase the disk space on a virtual machine:
In the Azure portal, select All services > Virtual Machines.
Select the virtual machine.
If the virtual machine is running, click Stop.
Under Settings, select Disks.
Click the OS Disk name.
Under Settings, select Configuration.
In the Size field, enter the disk size appropriate to meet the requirements of the machine. For example, 4502Vaz machines require 3600 GB of disk space.
Click Save.
