3.6.2.3 End Device Wizard Use the End Device Wizard to automatically configure a zone set and associated zone
groups by grouping end devices. Each window of the wizard includes instructions to
guide you through the configuration process.
This wizard uses a snapshot of the current domain to determine the available end
devices and then displays lists of initiators and targets. Type the zone set name
(maximum of 28 characters) and bundle one or more initiators with one or more targets
into a zone by selecting them from these lists. You can define multiple zones as needed
in order to meet your zoning requirements. Zones can overlap, but zones that are
subsets of larger zones are removed. The wizard forces devices that share the same
ZPSDS entry point (siblings) into the same zone by automatically selecting all siblings
when you select a single sibling. You can delete the defined zones by selecting the
check box and clicking the Delete button.
After you define all the zones, the wizard uses the zone definitions to create the
minimal number of zone groups and to configure their permissions. The wizard creates
one zone group per defined zone, populating the zone group with the ZPSDS entry
point phys of the end devices in that zone, and setting up permission for the phys in
the zone group to communicate with each other.
The wizard then compares each zone group to all other zone groups, including zone
groups created during this process, searching for phys that are in both zone groups. If it
finds any such phys (parents), it creates a new zone group (child) and moves the
identified phys to the child. The wizard then grants permission for the child’s phys to
communicate with each other, as well as with the phys of the two parent zone groups.
If one of the parent zone groups is emptied in this process, the wizard transfers all
permissions from the parent to the child. Empty zone groups are later ignored and are
not transferred to the zone manager.
The wizard creates the zone set and associated zone group when you click the Apply
button. The wizard assigns to zone groups the names <zone set name> + #001, <zone
set name> + #002, and so on. If the number of generated zone groups exceeds the
maximum number of 248, the wizard displays an error message.
