9 If you selected Custom, type a number of shares in the text box.
10 In the Limit - IOPs box, enter the upper limit of storage resources to allocate to the virtual machine,
or select Unlimited.
This value is the upper limit of I/O operations per second allocated to the virtual disk.
11 Accept the default or select a different virtual device node.
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 share a data disk with another virtual machine that is
using a Buslogic controller with bus sharing turned on.
12 (Optional) Select a disk mode and click OK.
Option Description
Dependent Dependent disks are included in snapshots.
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.
Add an Existing Hard Disk to a Virtual Machine
You can add an existing virtual hard disk to a virtual machine when you customize the virtual machine
hardware during the virtual machine creation process or after the virtual machine is created. For example,
you might want to add an existing hard disk that is preconfigured as a boot disk.
During virtual machine creation, a hard disk and a SCSI or SATA controller are added to the virtual
machine by default, based on the guest operating system that you select. If this disk does not meet your
needs, you can remove it and add an existing hard disk at the end of the creation process.
Prerequisites
n
Make sure that you are familiar with controller and virtual device node behavior for different virtual
hard disk configurations. See Add a Hard Disk to a Virtual Machine.
n
Before you add disks greater than 2TB to a virtual machine, see Large Capacity Virtual Disk
Conditions and Limitations.
n
Verify that you have the Virtual machine.Configuration.Add existing disk privilege on the
destination folder or datastore.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
