vSphere Storage 10 Select a compatibility mode. Option Description Physical Allows the guest operating system to access the hardware directly. Physical compatibility is useful if you are using SAN-aware applications on the virtual machine. However, a virtual machine with a physical compatibility RDM cannot be cloned, made into a template, or migrated if the migration involves copying the disk. Virtual Allows the RDM to behave as if it were a virtual disk, so you can use such features as taking snapshots, cloning, and so on. When you clone the disk or make a template out of it, the contents of the LUN are copied into a .vmdk virtual disk file. When you migrate a virtual compatibility mode RDM, you can migrate the mapping file or copy the contents of the LUN into a virtual disk. 11 If you selected virtual compatibility mode, select a disk mode. Disk modes are not available for RDM disks using physical compatibility mode. 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. 12 Click OK. Manage Paths for a Mapped Raw LUN You can manage paths for mapped raw LUNs. Procedure 1 Log in as administrator or as the owner of the virtual machine to which the mapped disk belongs. 2 Select the virtual machine from the Inventory panel. 3 On the Summary tab, click Edit Settings. 4 On the Hardware tab, select Hard Disk, then click Manage Paths. 5 Use the Manage Paths dialog box to enable or disable your paths, set multipathing policy, and specify the preferred path. For information on managing paths, see Chapter 20, “Understanding Multipathing and Failover,” on page 193. 186 VMware, Inc.
Manage Paths for a Mapped LUN in the vSphere Web Client When you use virtual machines with RDMs, you can manage paths for mapped raw LUNs. Procedure 1 Browse to the virtual machine. a Select a datacenter, folder, cluster, resource pool, or host. b Click the Related Objects tab and click Virtual Machines. 2 Right-click the virtual machine and select Edit Settings. 3 Click the Virtual Hardware tab and click Hard Disk to expand the disk options menu. 4 Click Manage Paths. Chapter 18 Raw Device Mapping 5 Use the Edit Multipathing Policies dialog box to enable or disable paths, set multipathing policy, and specify the preferred path. For information on managing paths, see Chapter 20, “Understanding Multipathing and Failover,” on page 193. VMware, Inc. 187
