Fabric Zoning
140 High Availability Fabric Manager User Guide
Using WWNs
To identify a zone member by WWN, use the 16-digit WWN of the device. For
example:
10:00:08:00:88:40:C0:D4
In the HAFM and Product Manager, the WWN is preceded with the switch or
director manufacturer’s name. The WWN is assigned to the Fibre Channel
interface or HBA installed in devices such as servers or storage devices. Although
the device may also have a node WWN, this WWN is not used for zoning
identification. If you have assigned a nickname to the WWN through the
Configure Nicknames dialog box, that nickname displays when you point to the
WWN. In this case, you will assign the nickname as the zone member.
The advantage of identifying a zone member as the WWN of the attached device
is that the identification will not change if fiber cable connections to ports are
rearranged. This is especially important if you are using spare ports. You can
simply move the fiber cable to a spare port from a failed port and still maintain the
zoning configuration.
The disadvantage of identifying a zone member by the WWN is that removal and
replacement of a device HBA or Fibre Channel interface (thereby changing the
device WWN) disrupts zone operation and may incorrectly include or exclude a
device from a zone.
Using Port Numbers
To identify a zone member by port number, use the domain identification number
of the managed product and the port number on that managed product. For
example:
Domain 1, Port 1
Note: Port numbers cannot be used for zone members if the interoperability mode for
the switch or director is set to Open Fabric 1.0 mode.
Port numbers can be 0-n, with n representing the number of ports on the managed
product minus one. When you define a zone member by a port number, any device
attached through that port is included in the zone. A port number that you assign
as a zone member is automatically prefixed with the domain identification number
of the managed product.
