Bi-directional

Configuration -

Zoning and

Optional LUN

Mapping

Figure 8-3 provides an example of a bi-directional configuration using FC/SCSI Tape Pipelining with Fibre Channel switch zones. The zones for this example are defined in Table 8-2. See the “Required Fibre Channel Switch Zoning” section on page -4 to determine when zoning is necessary.

The Edge will do automatic host LUN mapping on a first learned basis, which will fill the host LUN map from the lowest to the highest order. Static LUN mapping can be used to designate the desired order of the host LUN map, as in this example. To determine why and when to do static mapping, see the “Required Static Edge LUN Mapping” section. Table 8-4 and Table 8-5 (page -7) define the static Edge LUN mapping for nodes 10 and 20.

	Mapping
Required Fibre	Fibre Channel switch zoning is required to isolate individual devices
Channel Switch	from specific servers. When an UltraNet Edge 3000 is part of a
Zoning	network configuration, it is automatically mapped to its peer. Devices
	that are visible to one node are automatically mapped into the peer
	node’s LUN map and vice versa. When a zone is defined, the devices
	an Edge node has access to are determined by the members defined
	in its zone.
