McDATA 3000 manual Required Static, Edge LUN Mapping, Fibre Channel Switch Zone Device FC Switch

Network Configuration Examples

Note: McDATA prefers World Wide Name (WWN) zoning over port zoning. It allows the zoning to continue working when cables are moved from port to port during switch troubleshooting. Also, when using interop mode, it is the only allowable zoning method.

	Zone 2	Server C, Edge 10
	Zone 3	Server C, Tape C1, Tape C2, Tape C3, Media Changer 1
	Zone 4	Edge 10, Tape B2, Media Changer 1
FC Switch 2	Zone 1	Server B, Edge 20

	Zone 3	Edge 20, Tape A1, Tape A2, Tape C4, Media Changer 2

Required Static	The Automatic DataPath Mapping function of the Edge will
Edge LUN Mapping	automatically discover and map host LUNs on a first learned basis. It
	will fill the host LUN map from the lowest to the highest order. Static
	Edge LUN mapping should be used when a specific order is desired
	in the host LUN table.
	When using static LUN mapping to configure a remote target LUN,
	the automatic LUN discovery function is disabled for that target. This
	allows a method for “zoning” remote LUNs available through this
	pair of Edges.
	A configurable number of LUNs (default is 8) will be attempted to be
	discovered for each discovered remote target. This is configured in
	the Discover LUN Count field on page -35 and page -40. If the
	remote target LUN is out of this range, this LUN will need to be
	statically mapped.
