Learn about Granting Logical Drive Access To Hosts and Host Groups

Related Topics

After defining the storage partition topology, you can begin to assign logical drive access to the host groups or hosts defined in the Topology View of the Mappings View window.

Typically, logical drive access is defined by assigning a logical drive-to-LUN mapping using the Storage Partitioning Wizard, allowing you to grant a host group or host access to a particular logical drive (or a number of logical drives) in the storage subsystem. To learn more about the Wizard, see A Preview of the Storage Partitioning Wizard.

Important:

Granting Logical Drive Access to Host Groups

In the following example, three storage partitions have been defined.

The first storage partition consists of Logical Drive Financial. This logical drive is accessed by Host KC-B using LUN 5. Even though Host KC-B is part of the logical Host Group Kansas City, Host KC-A cannot access this logical drive because the logical drive-to-LUN mapping was created with Host KC-B rather than the Host Group Kansas City.

The second storage partition consists of Logical Drives Legal and Engineering. These logical drives are accessed by Hosts KC-A and KC-B in Host Group Kansas City using LUNs 2 and 4, respectively.

The third storage partition consists of Logical Drives Marketing and H Resources. These logical drives are accessed by Hosts Omaha A and B in Host Group Omaha using LUNs 7 and 2, respectively.

Granting Logical Drive Access to Hosts

In the following example, Host Omaha has been granted access to Logical Drive Legal through LUN 6 using either of its host ports. Host Kansas City has been granted access to Logical Drive Financial through LUN 6 and Logical Drive Engineering through LUN 7 using either of its host ports. Note that the same LUN (LUN 6 in this example) can be used for logical drive access for both hosts (Omaha and Kansas City), because each host has its own LUN address space.
