LUN masking considerations
The node WWN and port WWN of the local switch are used to query LUNs on the physical target. If
the physical target uses LUN masking to control access, these WWNs must be added to the LUN
masking to ensure that the LUN query returns the LUNs to the switch.
You can obtain these WWNs in either of two ways:
Enter the
iscsiCfg
--
easycreate tgt
command with the
-s
option to return the node and port
WWNs of the switch.
The following is an example.
switch:admin>
iscsicfg --easycreate tgt -s
The following WWNs will be used for any easycreate operation from this switch:
Node WWN: 10:00:00:60:69:80:04:4a
Port WWN: 21:fd:00:60:69:80:04:4a
Enter the
fcLunQuery
command with the
-s
option to return the node and port WWNs of the
switch.
The following is an example.
switch:admin>
fclunquery -s
The following WWNs will be used for any lun query from this switch:
Node WWN: 10:00:00:60:69:80:04:4a
Port WWN: 21:fd:00:60:69:80:04:4a
iSCSI FC zoning overview
After you have finished setting up the iSCSI target gateway, you can create an iSCSI FC zone for
discovery domains. However, if you do not have a zoning license, or if zoning is not implemented,
you cannot create an iSCSI FC zone for discovery domains.
Depending on whether you have an effective zone configuration enabled in the current fabric, you
will be able to choose where to put the iSCSI FC zone. It can be either contained in a defined
configuration or integrated into the effective configuration.
Figure 36
on page 277 illustrates a
defined iSCSI FC Zone containing iSCSI virtual initiators and FC targets.
