LSISAS6160 SAS Switch User Guide Chapter 3: SAS Domain Manager Graphical User Interface | Domain Tab
If the topology supports the configuration, the wizard builds two zone groups: one for
the initiators, and one for the targets, with the names <zone set name> + #001 and
<zone set name> + #002. The wizard scans through the domain and assigns to one zone
group all the ZPSDS entry point phys that are upstream from initiators. The wizard
assigns to another zone group all the ZPSDS entry point phys that are upstream from
targets. The wizard then sets up permissions to allow the two zone groups to
communicate with each other, but it prevents phys in one zone group from making
connections to each other. When you click the Apply button, the wizard creates the
zone set and the two associated zone groups.
3.6.2.2 Connector Wizard Use the Connector Wizard to automatically configure a zone set and associated zone
groups by grouping connectors on the edge of the ZPSDS. Each window of the wizard
includes instructions to guide you through the configuration process.
The wizard uses a snapshot of the current domain to identify the connectors on the
edge of the ZPSDS and then displays a list of these connectors. (The list does not
include connectors that link expanders within the ZPSDS.) Type the zone set name
(maximum of 28 characters) and bundle the connectors into zones by selecting one or
more connectors from the list. You can define multiple zones as needed in order to
meet your zoning requirements. Zones can overlap, but the wizard removes zones that
are subsets of larger zones. 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 phys associated
with the connectors 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. It 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.
NOTE: If phys on the edge of the ZPSDS are associated with connectors, then their
connectors are displayed in the selection list. If phys on the edge of the ZPSDS are not
associated with connectors, but they have formed into ports (they are connected to a
device), then ports are displayed in the selection list. If phys on the edge of the ZPSDS
are not associated with connectors, and have not formed into ports, individual phys are
displayed in the selection list.
