ID Mapping
There are two options for ID Mapping with the SV Router FC-FC 3: loop mode and point-to-
point mode.
Loop Mode
The SV Router FC-FC 3 contains a mapping table/SAN Database in its non-volatile memory
that maps an FC LUN to each of the attached drives and all other devices that are part of the
FC storage loop. This map represents the address for each device mapped. Each FC LUN is set
to correspond with a particular FC Loop ID that was allocated during the initial loop (or bus)
arbitration process (the loop arbitration process takes place among all elements connected to
the device side loop that a particular host can see).
The SV Router FC-FC 3 can use any of 126 FC ports, with FC LUN IDs 0 to 125. The SV
Router FC-FC 3 is assigned an FC Loop ID independently for both the device and host sides.
•
The host side of the SV Router FC-FC 3 acts as a target and receives commands sent by the
host.
•
The device side of the SV Router FC-FC 3 acts as an initiator and sends commands to the
drives.
The host side component responds to one particular FC Loop ID on the host side loop, and the
device side of the SV Router FC-FC 3 responds to an unrelated FC Loop ID on the device side
loop. All SV Router FC-FC 3s in a loop must have a different Loop ID.
Using the User Service Utility Interface, you can specify a soft ID or a hard ID for both the
host side (see
‘Fibre Channel Host-Side Configuration Menu’ on page 42 ) and the device side
(see ‘Fibre Channel Device-Side Configuration Menu’ on page 44 ). The SV Router FC-FC 3
creates the mapping according to these choices.
Point-To-Point Mode
Point-to-point mode uses a single path between the ports. The devices can communicate, so
there is no need for addressing.
If both devices are capable of operating in point-to-point mode, both ports should be set to use
point-to-point.
