• Deleting all zone information, page 69
Introduction to Zoning
HP Advanced Zoning is an optional, licensed feature that allows partitioning of a SAN into logical
groupings of devices that have access to each other. These logical groupings are called zones. Zoning
allows devices in a fabric to see some devices and not others. Using zoning, administrators can control
access to devices. For example, you can partition the SAN into two zones, winzone and unixzone, so that
the Windows servers and storage do not interact with UNIX
®
servers and storage. See ”Verifying,
installing, and removing licenses” on page 34 for information on adding a zoning license.
Zoning terminology
This chapter uses the following terminology to describe zoning:
zone A set of devices or ports that can communicate only with other devices or
ports within the set.
alias A logical group of ports or WWNs. An alias is a way of representing one
or more ports or devices by a more familiar name.
Specifying groups of ports or devices as an alias makes zone
configuration easier, by enabling you to configure zones using an alias
rather than a long string of individual members. For example, you might
assign all the WWNs of all the disks in a particular JBOD to the alias
myJBOD. Then all of those devices can be added easily to any zone by
adding the myJBOD alias to that zone.
zone member An alias; port, domain ID and port pair; port WWN or node WWN that is
part of a zone.
configuration A specified set of zones. A fabric can store any number of zone
configurations, but only one configuration is active at a time.
defined zone configuration The set of all zone configurations defined in the fabric.
effective zone configuration The currently enabled zone configuration (also known as the active zone
configuration). Only one configuration can be enabled at a time. If no
configuration is enabled, no zones are enforced and all devices can see
each other. You cannot modify the effective configuration.
