Appendix: Setting Zoning

Zoning Features

After completing login to the console of the 8G FC Switch, provide proper setting for the zoning of
the 8G FC Switch according to the procedure below.
The 8G FC Switch has two zoning features, WWN mode zoning and port mode zoning.
Port Mode Zoning:
Port mode zoning is a feature to separate SFP+ ports by zone by specifying the Domain ID and
the port number set in the 8G FC Switch.
NOTE:
The same SFP+ port can belong in more than one zone.
The devices can communicate with the devices only which connect to the SFP+
ports belonging in the same zone.
Since the port mode zoning is managed by usinig the Domain ID and the SFP+
port number which is specific to each 8G FC Switch, zoning resetting is not
required in maintenance replacement when a failure occures in the device
connecting to the 8G FC Switch. However, Fibre Channel devices must be
connected to the SFP+ ports which are set zoning because access are limited for
each SFP+ port in each zone.
WWN Mode Zoning:
WWN mode zoning is a feature to separate devides by zone by using individual WWPn that the
Fibre Channel devices have.
NOTE:
The same WWpn can belong in more than one zone.
The devices can communicate with the devices only which have WWpn belonging
in the same zone.
Since accesses are limited by using WWPn, the device of maintenance
replacement can communicate even if it is connected to any SFP+ port of the 8G
FC Switch when a failure occurs in the device connecting to the 8G FC Switch.
However, since WWPn is an individual value of the device and the WWPn will
change by replacement, zoning resetting is required to change WWPn setting to
the replaced Fibre Channel device.
If the Domain ID and the port number change in maintenance replacement of the storage
device, the hardware path may change in some host OS.
Setting at shipment from factory
Any zoning is not set when an 8G FC Switch is shipped from the factory.
Every connected device can communicate with any other devices.
