The following tutorial can be used as a guide to set up Storage Partitioning on a storage subsystem. Keep in mind that there are other ways to configure a storage subsystem; this is presented as one possible scenario. The tutorial explains how to define the topology and logical drive-to-LUN mappings shown below:
Four hosts (Omaha A and B, and KC-A and B) are connected to Storage Subsystem Midwest. The administrator of the storage subsystem should make sure that Omaha A and B have access to Logical Drives Marketing and H Resources and KC-A and KC-B have access to Logical Drives Legal and Engineering. In addition, the administrator wants Host KC-B to have exclusive access to Logical Drive Financial. To accomplish this, the following steps must be done:
Important: If your storage subsystem is directly managed and has the Access Logical Drive
1 |
Create each logical drive (Financial, Legal, Engineering, Marketing, and H Resources) according to the procedures in Creating a Logical Drive. When entering logical drive-to-LUN mapping settings, use recommended settings or select the Map later with Storage Partitioning feature. |
2 |
Define the host groups (Omaha and Kansas City) according to the procedures in Defining a Host Group. Host groups must be created because multiple hosts must have access to the same logical drives. |
3 |
Define the hosts (Omaha A and B and KC-A and B) under the host groups according to the procedures in Defining a Host. |
4 |
Define the host ports (Omaha A1, A2, B1, and B2 and KC-A1, A2, B1, and B2) according to the procedures in Defining a Host Port. The host ports are the topological entity that lets the hosts access the logical drives. |
5 |
Assign access for each host group or host according to the procedures in Using the Storage Partitioning Wizard. For example, select Host KC-B and define an exclusive logical drive-to-LUN mapping for Logical Drive Financial (one storage partition). Then, select Host Group Kansas City and define logical drive-to-LUN mappings for Logical Drives Legal and Engineering (a second storage partition). Finally, select Host Group Omaha and define logical drive-to-LUN mappings for Logical Drives Marketing and H Resources (a third storage partition). |
After completing all the steps in the previous procedure, the topology and logical drive-to-LUN mappings in the Mappings View window would look like the following:
