Create Virtual Machines with RDMs in the <strong>vSphere</strong> Web Client<br />
When you give your virtual machine direct access to a raw SAN LUN, you create an RDM disk that resides on<br />
a VMFS datastore and points to the LUN. You can create the RDM as an initial disk for a new virtual machine<br />
or add it to an existing virtual machine. When creating the RDM, you specify the LUN to be mapped and the<br />
datastore on which to put the RDM.<br />
Although the RDM disk file has the same.vmdk extension as a regular virtual disk file, the RDM contains only<br />
mapping information. The actual virtual disk data is stored directly on the LUN.<br />
This procedure assumes that you are creating a new virtual machine. For information, see the <strong>vSphere</strong> Virtual<br />
Machine Administration documentation.<br />
Procedure<br />
1 Right-click any inventory object that is a valid parent object of a virtual machine, such as a datacenter,<br />
folder, cluster, resource pool, or host, and select New Virtual Machine.<br />
2 Select Create a new virtual machine and click Next.<br />
3 Follow the steps required to create a virtual machine.<br />
4 On the Customize Hardware page, click the Virtual Hardware tab.<br />
5 (Optional) To delete the default virtual hard disk that the system created for your virtual machine, move<br />
your cursor over the disk and click the Remove icon.<br />
6 From the New drop-down menu at the bottom of the page, select RDM Disk and click Add.<br />
7 From the list of SAN devices or LUNs, select a raw LUN for your virtual machine to access directly and<br />
click OK.<br />
The system creates an RDM disk that maps your virtual machine to the target LUN. The RDM disk is<br />
shown on the list of virtual devices as a new hard disk.<br />
8 Click the New Hard Disk triangle to expand the properties for the RDM disk.<br />
9 Select a location for the RDM disk.<br />
Chapter 18 Raw Device Mapping<br />
You can place the RDM on the same datastore where your virtual machine configuration files reside, or<br />
select a different datastore.<br />
NOTE To use vMotion for virtual machines with enabled NPIV, make sure that the RDM files and the<br />
virtual machine files are located on the same datastore. You cannot perform <strong>Storage</strong> vMotion when NPIV<br />
is enabled.<br />
