Chapter 20 iSCSI Configuration
Configuring iSCSI
Step 4 Set the iSCSI node name or IP address and VSAN membership.
Step 5 In the Node WWN section, check the Persistent check box.
Step 6 Check the System Assigned check box if you want the switch to assign the nWWN. Or leave this
unchecked and set Static WWN field.
Step 7 In the Port WWN section, check the Persistent check box if you want to statically map pWWNs to the
iSCSI initiator.
Step 8 If persistent, check the System Assigned check box and set the number of pWWNs to reserve for this
iSCSI initiator if you want the switch to assign pWWNs.
Or leave this unchecked and set one or more pWWNs for this iSCSI initiator.
Step 9 Optionally set the AuthUser field if authentication is enabled. See the “iSCSI User Authentication”
section on page 20-17.
Step 10 Click Create to create this iSCSI initiator or click Cancel to close the dialog box without creating a new
iSCSI initiator.
iSCSI Proxy Initiators
Note When an interface is in the proxy initiator mode, you can only configure Fibre Channel access control
(zoning) based on the Fibre Channel interface attributes—the WWN pair and available FCIDs. You
cannot configure zoning using iSCSI attributes such as the IP address or the iQN name of the iSCSI
initiator. To enforce initiator-based access control, use iSCSI based access control (see the “Access
Control in iSCSI” section on page 20-16).
By default, each iSCSI initiator appears as one Fibre Channel initiator in transparent mode in the Fibre
Channel fabric. For some storage arrays, this appearance requires the initiator’s pWWN to be manually
configured for access control purposes. This process can be quite cumbersome. The proxy initiator
feature allows all iSCSI initiators to connect through one IPS port making it appear as one Fibre Channel
port per VSAN. It simplifies the task of configuring the pWWN for each new initiator on the storage
array, and of configuring Fibre Channel access control such as zoning. This feature along with static
target importing (using LUN mapping) results in the configuration being performed only on the switch
