Zoning terminology
The following Advanced Zoning terms are used in the procedures:
• A zone is a region within the fabric where a specified group of fabric-connected devices (called zone
members) have access to one another. When zoning is enabled, objects not explicitly defined in a
zone are isolated, and members in the zoned fabric do not have access to them.
• A group of one or more zones is called a zone configuration.
• The complete set of all zone members defined in a fabric is called the defined zone configuration.
• Zoning procedures change zone objects in the defined configuration. When you enable a
configuration with the
cfgenable
command, it becomes the effective zone configuration.
• A copy of the defined zone configuration (plus the name of the effective zone configuration) can be
saved with the
cfgsave
command. The resulting saved zone configuration is restored after a switch
reboot. If you make changes to the defined zone configuration but do not save them, there will be
differences between the defined zone configuration and the saved zone configuration.
To use zoning, you must install zoning licenses on all the switches in the fabric before attempting to bring
a switch into the fabric. If a zoning license is removed, you must make sure it is reinstalled properly on
the affected switch before attempting the
cfgenable
zoning operation. Failure to follow these steps can
cause inconsistency of the zoning configuration on the affected switches if a zoning operation be
attempted from a remote switch in the fabric. On the affected switches, an error message indicates that
the zoning license is missing.
To list the commands associated with zoning, use the
zonehelp
command.
For detailed information on the zoning commands used in the procedures, refer to the HP StorageWorks
Fabric OS 4.x command reference guide or to the online man page for each command.
