ATTENTION ! 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 (Domain_ID) and physical port
number of the director or fabric switch port to which the device is
attached.
ATTENTION ! If zoning is implemented by port number, a change to the
director or fabric switch fiber-optic cable configuration disrupts zone
operation and may incorrectly include or exclude a device from a zone.
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 multiswitch fabric. Only one zone set can be enabled at one time.
Zone members are defined and zones or zone sets are created using
the SAN management application. McDATA products support the
following zoning features:
• 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 in the zoning library is 64.
• Active zone set - the zone set that is active across all directors and
switches in a multiswitch fabric. For the active zone set:
— When a specific zone set is activated, that zone set replaces the
active zone set.
— If the active zone set is disabled, all devices attached to the
fabric become members of the default zone.
— All devices not included as members of the active zone set are
included in the default zone.
• Default zone - the default zone consists of all devices not
configured as members of a zone in the active zone set. If there is
no active zone set, then all devices attached to the fabric are in the
default zone. For the default zone:
