System information
11 Select the number of virtual processors in the virtual machine from the pull-down list, and click Next.
12 Configure the virtual machine’s memory size by selecting the number of megabytes, and click Next.
13 Configure network connections, and click Next.
14 Choose the type of SCSI adapter you want to use with the virtual machine.
15 Select Raw Device Mapping, and click Next.
16 From a list of SAN disks or LUNs, select a raw LUN you want your virtual machine to access directly.
17 Select a datastore for the RDM mapping file.
You can place the RDM file on the same datastore where your virtual machine files reside, or select a
different datastore.
NOTE If you want to use VMotion for a virtual machine with enabled NPIV, make sure that the RDM file
is located on the same datastore where the virtual machine configuration file resides. You cannot perform
Storage VMotion, or VMotion between datastores, when NPIV is enabled.
18 Select a compatibility mode, either physical or virtual.
Depending on your choice, subsequent screens offer different options.
n
Physical compatibility mode allows the guest operating system to access the hardware directly.
Physical compatibility is useful if you are using SAN-aware applications in the virtual machine.
However, a virtual machine with the physical compatibility RDM cannot be cloned, made into a
template, or migrated if the migration involves copying the disk.
n
Virtual compatibility allows the RDM to behave as if it were a virtual disk, so you can use such features
as snapshotting, cloning, and so on.
19 On the Specify Advanced Options page, you can change the virtual device node and click Next.
20 Assign WWNs to the virtual machine.
21 On the Ready to Complete New Virtual Machine page, select the Edit the virtual machine settings before
completion check box and click Next.
Assign or Modify WWNs
After you create a virtual machine with an RDM, you can assign virtual WWNs to it. You can also modify
WWN assignments for an existing virtual machine with an RDM.
Prerequisites
Make sure to power off the virtual machine if you want to edit the existing WWNs.
Before you begin, ensure that your SAN administrator has provisioned the storage LUN ACL to allow the
virtual machine’s ESX/ESXi host to access it.
