Scenario
After a disk is mounted to a physical server, users must log in to the server to initialize the disk, that is, formatting the disk. Then the disk can be used normally.
System Disk
A system disk needs no initialization. The system disk is generated when you create a physical server and is automatically initialized. The default disk partition form is the Master Boot Record (MBR).
Data Disk
l A data disk is directly created when you create a physical server and the data disk will be automatically mounted to the server.
l Create a data disk and then mount the data disk to the physical server.
l Local data disk of the physical server.
When the data disk is created in the above three situations, the data disk can be used only when being initialized. Please select an appropriate partition form according to your actual business planning.
