The Indexed map is initially empty and can be modified by the user, however, this is not

recommended.

The Auto Assigned map is built dynamically, and contains all the devices found during discovery. This

map changes automatically any time the discovery process finds a change in the devices attached to

the network storage router. This map can be displayed, but cannot be modified directly by the user.

The SCC map is only available on the FC port and contains a single entry. LUN 0 is an network

storage router LUN, and access to devices behind the controller is handled by using SCC logical unit

addressing.

When a host sends a command to the network storage router, the network storage router selects which

map to use, based on the ID of the host sending the command. For FC ports, the host ID is the World

Wide Name. For SCSI buses, the host ID is the initiator ID (0 - 15). When a host is unknown to the

network storage router, or is not attached to a specific map, the network storage router uses the default

setting for mapping. The default setting for each port can be set to Auto-assigned, Indexed, or SCC

(which applies to the FC port only) by the user.
