Using Zoning 23
Adding a Switch
When a new switch is added to the fabric, it automatically takes on the zone
configuration information from the fabric. To add the new switch, attach
the E_ports; the new switch is incorporated into the fabric and the enabled
zone configuration.
Merging Fabrics
When a new fabric (with no zone configuration information) is added to an
existing zoned fabric, all switches in the new fabric take on the zoning
characteristics present in the existing fabric.
If two fabrics that both contain zone configuration information are joined,
the fabrics attempt to merge the two sets of zone configuration data.
In the simplest case, where both fabrics have identical zone configuration
data and the same configuration enabled, the fabrics join to make one larger
fabric with the same zone configuration enabled across the new fabric.
If the fabrics have different zone configuration data, the two sets of zone
configuration data are merged, if possible. If not possible, the interswitch
link (ISL) is segmented. A merge is not possible if any of the following
exist:
Configuration mismatch Zoning is enabled in both fabrics, and the
zone configurations that are enabled are
different in each fabric.
Type mismatch The name of a zone object in one fabric is
used for a different type of zone object in
the other fabric.
Content mismatch The definition of a zone object in one fabric
is different from the definition of a zone
object with the same name in the other
fabric.
