Common mechanisms of identifying members in Fibre Channel Zone are the following (see
"Configuring and Managing Zones"
•
•
In the case of iSCSI, behind an iSCSI interface multiple iSCSI devices may be connected. Interface
based zoning may not be useful because all the iSCSI devices behind the interface will automatically be
within the same zone.
In transparent initiator mode (where one Fibre Channel virtual N port is created for each iSCSI host as
described in the
mapping then the standard Fibre Channel deice pWWN-based zoning membership mechanism can be
used.
Zoning membership mechanism has been enhanced to add iSCSI devices to zones based on the
following:
•
•
For iSCSI hosts that do not have a static WWN mapping, the feature allows the IP address or iSCSI node
name to be specified as zone members. Note that iSCSI hosts that have static WWN mapping can also
use these features. IP address based zone membership allows multiple devices to be specified in one
command by providing the subnet mask.
Note
In proxy initiator mode, all iSCSI devices connecting to an IPS port gain access to the Fibre Channel
fabric via a single virtual Fibre Channel N port. Thus, zoning based on the iSCSI node name or IP
address will not have any effect. If zoning based on pWWN is used then all iSCSI devices connecting to
that IPS port will be put in the same zone. To implement individual initiator access control in proxy
initiator mode, configure a iSCSI ACL on the virtual target (see the
section on page
To add an iSCSI initiator to the zone database, follow these steps:

Purpose
Enters configuration mode.
Creates a zone name for the iSCSI devices in the
IPS module or MPS-14/2 module to be included.
Assigns an iSCSI node name-based membership
into a zone.
Deletes the specified device from a zone.
Assigns an iSCSI IP address-based membership
into a zone.
Deletes the identified device from a zone.
Assigns an iSCSI port WWN-based membership
into a zone.
Deletes the device identified by the port WWN
from a zone.
