Configuring Zones

Zoning is configured through the HAFM application by authorizing or restricting
access to name server information associated with device node ports (N_Ports)
that attach to director or switch fabric ports (F_Ports). A device N_Port can
belong to multiple zones. Zoning is configured by:
A zone contains a set of attached devices that can access each other. Zones are
grouped into zone sets. A zone set is a group of zones that is enabled (activated) or
disabled across all directors and switches in a multi-switch fabric. Only one zone
set can be enabled at one time. Zone members are defined and zones or zone sets
are created using the HAFM application. HP products support the following
zoning features:
156
The eight-byte (64-digit) World Wide Name (WWN) assigned to the HBA or
Fibre Channel interface installed in the device connected to the director or
switch (recommended method).
Caution: If zoning is implemented by WWN, removal and replacement of a
device HBA or Fibre Channel interface (thereby changing the device WWN)
disrupts zone operation and may incorrectly exclude a device from a zone.
The domain identification (ID) and physical port number of the director or
switch port to which the device is attached.
Caution: If zoning is implemented by port number, a change to the director
or switch fiber-optic cable configuration disrupts zone operation and may
incorrectly include or exclude a device from a zone.
Zone members — The maximum number of members configurable for a
zone is 4,096.
Number of zones — The maximum number of configurable zones in a zone
set is 1,023 (1,024 including the default zone).
Number of zone sets — The maximum number of configurable zones sets is
64.
Active zone set — The zone set that is active across all directors and switches
in a multi-switch fabric. For the active zone set:
