Use this option to grant logical drive access to a particular host group and/or host and to define the logical unit number (LUN) that should be used to access it.
Important:
When you have defined a specific logical drive-to-LUN mapping for a host group or host that is currently under the Default Host Group, the host group or host moves out of the Default Host Group and under the Storage Subsystem (root) node indicating that the host group or host has a specific logical drive-to-LUN mapping. Once a specific logical drive-to-LUN mapping is defined for a host group or host, the host group or host no longer has access to the logical drives (if any) in the Default Host Group.
Example:
|
In the example to the left, the host group St. Louis has been defined, but currently does not have any defined hosts, host ports, or specific logical drive-to-LUN mappings. |
|
|
|
In the example to the left, associated hosts and host ports have been defined for the St. Louis host group. Also, a specific logical drive-to-LUN mapping has been defined for the St. Louis host group. |

How to Define a Logical Drive-to-LUN Mapping
1 |
From the Storage Partitioning Definitions Window, select the Default Host Group, or a host group or host from the Topology View; then, select either the Configure >> Logical Drive-to-LUN Mappings >> Define New Mapping pull-down menu option or Define New Mapping from the right-mouse pop-up menu.
|
||||||||
2 |
Select a single logical drive from the logical drive-to-LUN mapping table. The logical drive-to-LUN mapping table lists the names and unique logical drive identifiers (world-wide name) of the logical drives that are available for definition. |
||||||||
3 |
Select a single Logical Unit Number (0 through 31) from the LUN drop-down list box. |
||||||||
4 |
Select Apply to save the logical drive-to-LUN mapping and leave the dialog open. Select OK to save the logical drive-to-LUN mapping and close the dialog. |
