Physical Planning Considerations
134 SAN High Availability Planning Guide
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.
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:
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:
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.
