Chapter 50 Configuring iSCSI
iSCSI Authentication Setup Guidelines and Scenarios
Figure 50-41 Ethernet PortChannel-Based iSCSI High Availability
In Figure 50-41, each iSCSI host discovers one iSCSI target for every physical Fibre Channel target. The
iSCSI session from the iSCSI host to the iSCSI virtual target (on the IPS port) uses one of the two
physical interfaces (because an iSCSI session uses one TCP connection). When the Gigabit Ethernet
interface fails, the IPS module and the Ethernet switch transparently forwards all the frames on to the
second Gigabit Ethernet interface.
Note If an Ethernet PortChannel is configured between the IPS module and an Ethernet switch, the load
balancing policy on the Ethernet switch must be based on source/destination IP address only, not port
numbers, for load balancing with VRRP to operate correctly.
iSCSI Authentication Setup Guidelines and Scenarios
This section provides guidelines on iSCSI authentication possibilities, setup requirements, and sample
scenarios. It includes the following authentication setup guidelines:
• No Authentication, page 50-56
• CHAP with Local Password Database, page 50-57
• CHAP with External RADIUS Server, page 50-57
• iSCSI Transparent Mode Initiator, page 50-58
• Target Storage Device Requiring LUN Mapping, page 50-62
Caution Changing the authentication of an iSCSI interface that is part of an iSLB VRRP group impacts load
balancing on the interface. See the
“Changing iSCSI Interface Parameters and the Impact on Load
Balancing” section on page 50-45.
No Authentication
Set the iSCSI authentication method to none to configure a network with no authentication.
In Fabric Manager, choose End Devices > iSCSI in the Physical Attributes pane. Then select the
Globals tab and set the AuthMethod drop-down menu to none and click Apply Changes.
