are defined by assigning a , which grants a or access to a particular (or a number of virtual disks) in a .

The Storage Partitioning Wizard helps you to quickly define a single storage partition. It guides you through the major steps required to specify which , , , and associated are to be included in the partition.

If a storage partition has not been defined (and the Storage Partitioning feature has been enabled), an informational dialog is displayed each time the is selected. The dialog emphasizes that the following topology must be defined before defining the actual storage partition:

1	Define the . Define host groups only if you have two or more hosts that will share access to the same virtual disks. Otherwise, skip to step 2. For more information, see Defining a Host Group.
2	Define the hosts that will access virtual disks on the storage array. For more information, see Defining a Host.
3	Define the that will allow a host to access virtual disks on the storage array. For more information, see Defining an HBA Host Port.
4	Define the storage partition using the Storage Partitioning Wizard. To learn more about the wizard, see A Preview of the Storage Partitioning Wizard. You can also define storage partitions by using the Define Additional Mapping dialog. For more information, see Defining Additional Virtual Disk-to-LUN Mapping.

Important:

You can include a in a partition. However, any hosts mapped to the secondary virtual disk will have read-only access until the virtual disk is promoted to a , or the mirror relationship is removed.

Storage Partitioning fails under the following conditions:

All virtual disk-to-LUN mappings are defined.
You attempted to create a virtual disk-to-LUN mapping for a host group that conflicts with an established virtual disk-to-LUN mapping for a host in the host group.
You attempted to create a virtual disk-to-LUN mapping for a host in a host group that conflicts with an established virtual disk-to-LUN mapping for the host group.

Storage Partitioning is unavailable under the following conditions:

The Storage Partitioning is not enabled. For information on enabling premium features, see Enabling Premium Features.
No valid host groups or hosts exist in the Mappings View.
No HBA host ports have been defined for the host being included in the partition.
All virtual disk-to-LUN mappings have been defined.

1	From the Topology pane of the Mappings View, select any node or object, and select Mappings >> Define >> Storage Partitioning.
2	Follow the directions on each of the dialogs, and click Next when ready to move to the next dialog.

The following list describes the dialogs you encounter when using the Storage Partitioning Wizard:

The Introduction dialog of the Wizard describes the process of creating a storage partition, and reminds you that the required virtual disks and host groups, hosts, or both must be created before continuing the wizard.
The Select Host Group or Host dialog enables you to select a single host group or host for which access is to be defined.
The Select Virtual Disks/LUNs dialog guides you through the process of selecting a virtual disk, and assigning a LUN that the host group or host will use to access the virtual disk. The wizard is completed on this dialog.
