identical zone contains only the same HBA and storage system ports you selected. If the zone contains additional members, it is not considered to be identical.
•If an identical zone exists, it is selected in the Zone pane.
•If an identical zone does not exist, the management server asks you to provide a name for the zone that will be created. The new zone appears in the Zone pane, even though it is not created until the job runs.
•Create new zone if there is no zone containing AT LEAST the selected zone members - The management server tries to find a zone that contains the HBA and storage system ports you selected.
•If a zone contains additional members, the management server selects that zone in the Zone pane.
•If the management cannot find a zone containing the HBA and storage system ports you selected, the management server asks you to name a zone that will be created. The new zone appears in the Zone pane, even though it is not created until the job runs.
IMPORTANT: (McDATA switches only) Path Provisioning looks for the names of the active zone set and of the active zones and all of their saved counterparts in the zoning library in EFC Manager. The provisioning job only occurs if those names match.
About the Use Switch Port Zoning Mode Option
By default, Path Provisioning creates zones through WWNs, which means it looks for a port on a host and a port on a storage system to create the zone. Zoning through WWNs is not dependent upon the switch. This means you could change switches as long as the host and storage system are able to access each other through the network.
To create zones through switch port zoning, select the Use Switch Port Zoning Mode option, and then select ports on a switch to create your zone. For example, if ports 1 and 2 on a switch are designated as a zone, whatever is connected to either of these ports will be a part of the zone.
Display Zone Alias Option
Select the Display Zone Alias option to prevent you from creating duplicate zone aliases on the same port. If you have this option selected when path provisioning detects a Fabric support zone alias provisioning feature, all zone aliases in this Fabric will be also listed on the Path Provisioning Zone panel. If the selected ports are part of any existing zone alias provisioning feature, such zone aliases will be selected and highlighted to prevent you from creating duplicate zone aliases on the same port.
Automatically Configure Zoning
To automatically configure zoning:
1.Click the 
button above the Zone pane before you select a host.
2.Select Automatically create new zone if no existing zone containing HBA and storage system ports is detected.
3.Select one of the options discussed in the previous bulleted list, and click Apply.
