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.
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.
Procedure
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.
This option is read-only when editing a virtual machine that is powered on.
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.
Add a Hard Disk to a Virtual Machine in the vSphere Client
When you add a hard disk to a virtual machine, you can create a new virtual disk, add an existing virtual
disk, or add a mapped SAN LUN.
In most cases, you can accept the default device node. For a hard disk, a nondefault device node is useful to
control the boot order or to have different SCSI controller types. For example, you might want to boot from
an LSI Logic controller and use a Buslogic controller with bus sharing turned on to share a data disk with
another virtual machine.
NOTE You cannot use migration with vMotion to migrate virtual machines that use raw disks for clustering
purposes.
Procedure
1 In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.
2 Click the Hardware tab and click Add.
3 Select Hard Disk and click Next.
