Defining Additional Logical Drive-to-LUN Mapping

Related Topics

Use this option to define additional logical drive-to-LUN mappings for an existing storage partition.

Note: This option may also be used to define the initial logical drive-to-LUN mapping.

Important: An Access Logical Drive mapping is not required for directly managed storage subsystems. If the storage subsystem is directly managed, and an Access Logical Drive mapping is assigned to the Default Group, an Access Logical Drive mapping will be assigned to every host created from the Default Group. To prevent this from happening, delete the Access Logical Drive mapping from the Default Group. For more information, see Deleting a Host Port, Host, Host Group, or Logical Drive Mapping.

Procedure

1

From the Topology pane of the Mappings View, select the Default Group, Undefined Mappings node, an individual undefined mapping, a host group, a host, or an Access Logical Drive. Then, select the Mappings >> Define >> Additional Mapping pull-down menu option, or Define Additional Mapping from the right-mouse pop-up menu.

Result: The Define Additional Mapping dialog is displayed.

2

Select a host group or host to which the logical drive is to be mapped from the Host group or host drop-down list. All defined hosts, host groups, and the Default Group are displayed as options.

Note: If a host or host group is selected that does not have a host port defined, a warning dialog is displayed.

3

Select a single Logical Unit Number (LUN) (0 through 31) from the drop-down list.

Note: Only available LUNs are displayed.

4

Select the logical drive to be mapped to from the Logical Drive table. The table lists the names and capacity of the logical drives that are available for mapping, based on the host group or host selected.

Note: You can include a Secondary Logical Drive in a partition. However, any host(s) that are mapped to this logical drive will be unable to access it until it is promoted to a Primary Logical Drive .

5

Select Add to save the logical drive-to-LUN mapping, and leave the dialog open.

Note: The Add button remains unavailable until a host group, host, LUN, and logical drive are selected.

6

Repeat steps 2 through 5 to add multiple additional logical drives to the storage partition.

Note: Once a logical drive has been mapped once, it is no longer available in the Logical Drive table.

7

Select Close to exit the dialog.

Result: The logical drive-to-LUN mappings are saved. The Topology and Defined Mappings panes in the Mappings View are updated to reflect the additional mappings.
