Viewing the Logical Associations, 226 | Dell MD3200, MD3220 instruction

Viewing the Logical Associations

You can use the Associated Logical Elements option to view the logical associations among different virtual disks in a storage array. To view the associations for source virtual disks, snapshot virtual disks, and snapshot repository virtual disks:

1In the AMW, select the Logical tab or in the Topology pane of the Mappings tab.

2Select View→ Associated Logical Elements. Alternatively, you can right- click the virtual disk to open a pop-up menu and select View→ Associated Logical Elements.

If you select a virtual disk that does not have logical associations with other virtual disks, the Associated Logical Elements option is disabled.

NOTE: The View Associated Logical Elements dialog appears, which indicates the logical associations for the selected virtual disk.

3To close the View Associated Logical Elements dialog, click Close.

Viewing the Physical Associations

You can use the Associated Physical Components option to view the physical components that are associated with source virtual disks, snapshot virtual disks, snapshot repository virtual disks, disk groups, unconfigured capacity, and free capacity in a storage array.

To view the physical associations:

1In the AMW, select a node in the Logical pane of the Logical tab or in the Topology pane of the Mappings tab.

2Select View→ Associated Physical Components. Alternatively, if the selected node is a virtual disk, you can right-click the node to open a pop- up menu and select View→ Associated Physical Components. If the selected node is a disk group, unconfigured capacity, or free capacity, you can right-click the node to open a pop-up menu and select View→ Associated Physical Components.

The View Associated Physical Components dialog appears with blue dots next to the physical components that are associated with the selected node.

3To close the View Associated Physical Components dialog, click Close.
