> # Using Enclosures with DCNM-SAN Topology Maps

> Because not all devices are capable of responding to FC-GS-3 requests, different ports of a single server or storage subsystem may be displayed as individual end devices on the topology map. See the "Modifying the Device Grouping" topic to group these ports into a single enclosure for DCNM-SAN.

> Clicking Alias->Enclosure displays hosts and storage elements in the Information pane. This is a shortcut to naming enclosures. To use this shortcut, highlight each row in the host or storage table that you want grouped in an enclosure then click Alias -> Enclosure. This automatically sets the enclosure names of each selected row with the first token of the alias.
