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). |
6 |
Create additional storage partitions if backup support is required, according to the procedures in Defining Additional Logical Drive-to-LUN Mappings. For example, to backup all of the logical drives in Storage Subsystem Midwest, the additional storage partition 'Backup Server 1' is defined and mapped to all of the logical drives in the storage subsystem. A backup may then be made of all of the logical drives in Storage Subsystem Midwest. |
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:
