You can change the virtual device node, the size of the disk, and the persistence mode for virtual disk configuration for a virtual machine.
About this task
The Manage Paths feature for RDM disks is not available for virtual machines on legacy hosts running versions of ESX Server earlier than 3.0.
- In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.
- Click the Hardware tab and select the hard disk to modify.
The name of the disk file and the disk type (thick or thin) appear in the upper-right pane.
- Select a Virtual Device Node type from the drop-down menu.
- To change the size of the disk, enter a new value in the Provisioned Size text box.
- (Optional) : To change the way disks are affected by snapshots, click Independent and select an option.
Independent - Persistent
Disks in persistent mode behave like conventional disks on your physical computer. All data written to a disk in persistent mode are written permanently to the disk.
Independent - Nonpersistent
Changes to disks in nonpersistent mode are discarded when you power off or reset the virtual machine. With nonpersistent mode, you can restart the virtual machine with a virtual disk in the same state every time. Changes to the disk are written to and read from a redo log file that is deleted when you power off or reset.
