You can change the virtual device node, the size of the disk, and the persistence mode for virtual disk configuration for a virtual machine.

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.

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.

Description

Persistent

The disk operates normally except that changes to the disk are permanent even if the virtual machine is reverted to a snapshot.

Nonpersistent

The disk appears to operate normally, but whenever the virtual machine is powered off or reverted to a snapshot, the contents of the disk return to their original state. All later changes are discarded.

Independent disks are not affected by snapshots.

Click OK to save your changes and close the dialog box.
