Using Wwns - HP 316095-B21 - StorageWorks Edge Switch 2/24 User Manual

configure for a zone varies according to the number of zones in the zone set, the
length of the zone names, and other factors, but is essentially bounded by the
available nonvolatile random-access memory (NVRAM) in the managed product.
Note:
the switch or director is set to Open Fabric 1.0 mode. In this case, you must use node
WWNs as zone members.
The type of zone members identified for a zone may be mixed and matched. For
example, two members may be specified by a port number and the third member
by the WWN of the device.

Using WWNs

To identify a zone member by WWN, use the 16-digit WWN of the device. For
example:
In EWS the WWN displays with the switch or director manufacturer's name
before the WWN. 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.
Note:
This functionality is not available in EWS.
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.
