Configuration Overview
32 Network Storage Router e1200-160
Note: The router can respond to multiple Target IDs on a SCSI bus.
Both Fibre Channel ports and SCSI buses have predefined maps.
There are four predefined maps:
■ Indexed Map
■ Port 0 Device Map
■ Auto Assigned Maps
■ SCC Map
When a host sends a command, the router will select which map to use, based on
the port receiving the command and the ID of the host sending the command. For
Fibre Channel 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 or is not assigned a
specific map, the router will use the default map.
Indexed Map
An indexed map is initially empty.
Port 0 Device Map
The Port 0 Device Map should be used when editing and assigning oncoming
hosts.
Auto Assigned Map
An auto assigned map is built dynamically and contains all of the devices found
during discovery. This map will change automatically any time the discovery
process finds a change in the devices attached. This map cannot be modified by
the user.
SCC Map
An SCC map is only available on Fibre Channel ports and contains only a single
entry for LUN
0. This LUN is a router controller LUN. Access to attached devices
is managed using SCC logical unit addressing.
