Change the Virtual Disk Configuration in the vSphere Client

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

Note:

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.

1. In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.
2. 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.

3. Select a Virtual Device Node type from the drop-down menu.
4. To change the size of the disk, enter a new value in the Provisioned Size text box.
5. (Optional) : To change the way disks are affected by snapshots, click Independent and select an option.

   Option	Description
   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.

6. Click OK to save your changes.
