This section describes the zoning functions supported by the MSA Fabric Switch 6. It
describes zoning at the individual switch and describes how the
merge command
functions are used to support zoning across a Fabric.
Zoning Elements
Before setting up zoning, you must understand the following zoning elements:
• Zone Members
• Zones
• Zone Sets
CAUTION: Never add a zoned switch to an established fabric that has no zoning. If
a switch configured with zoning is added to a fabric that has no configured zoning,
the fabric’s HBAs and targets will no longer be able to communicate and the traffic in
the fabric will be disrupted. For best results, only add a switch configured with zoning
to a fabric configured with the same zoning configuration.
Zone Members
Zone members are Fibre Channel edge devices that are identified by their World
Wide Port Name (WWPN). Any device that you want to include in a zone must be
identified as a zone member. While internally the zone members are tracked by their
WWPN, you can create a Zone Member Name that acts as an alias for the device.
This makes it easier to identify the devices during configuration and operation. The
following are examples of Fibre Channel devices that can be named as zone
members:
• Servers
• Raid systems
• Disk drives
• Tape libraries
IMPORTANT: The World Wide Node Name (WWNN) of the Fibre Channel device cannot be
used to create a zone member. WWNN-bases zoning is expressly prohibited in the FC-MI
standard. Use World Wide Port Name (WWPN) to create a zone member.
