Prerequisites
n
Verify that you are familiar with controller and virtual device node behavior for dierent virtual hard
disk congurations.
n
Verify that you have the Virtual machine..Add existing disk privilege on the destination
folder or datastore.
Power o the virtual machine.
Procedure
1 Click Virtual Machines in the VMware Host Client inventory.
2 Right-click a virtual machine in the list and select Edit  from the pop-up menu.
3 On the Virtual Hardware tab, select Add hard disk and select Existing hard disk from the drop-down
menu.
4 (Optional) To delete an existing hard disk, move your pointer over the disk and click the Remove icon
(X).
The disk is removed from the virtual machine. If other virtual machines share the disk, the disk les are
not deleted.
5 In the Datastore column, expand a datastore, select a virtual machine folder, and select the disk to add.
The disk le appears in the Contents column. The File type menu shows the compatibility le types for
this disk.
6 Click Select and click Save to add the existing hard disk.
Use Disk Shares to Prioritize Virtual Machines in the VMware Host Client
You can change the disk resources for a virtual machine. If multiple virtual machines access the same VMFS
datastore and the same logical unit number (LUN), use disk shares to prioritize the level of access that
virtual machines have to resources. Disk shares distinguish high-priority from low-priority virtual
machines.
You can allocate the I/O bandwidth of the host to the virtual hard disks of a virtual machine. You cannot
pool disk I/O across a cluster.
The shares value represents the relative metric for controlling disk bandwidth to all virtual machines.
Disk shares are relevant only within a given host. The shares assigned to virtual machines on one host have
no eect on virtual machines on other hosts.
You can select an IOP limit, which sets an upper limit for storage resources that are allocated to a virtual
machine. IOPs are the number of I/O operations per second.
