Verifying IP connectivity
After you add the IP addresses of the routes, enter the
portCmd
command to ping a destination IP address
from one of your source IP interfaces on the GbE port and verify the Ethernet IP-IP connectivity.
This verification not only ensures that data packets can be sent to the remote interface, but also aids in
creating and modifying the ARP table:.
Adding ARP entries
It is not necessary to create additional ARP entries for iSCSI Target Gateway to work. The ARP entries for
the IP interfaces will be automatically created when you complete the route for the IP by verifying it with the
ping command outlined in the previous section.
Use this command to configure additional address resolution protocol (ARP) entries for the IP interfaces on
the gigabit Ethernet (GbE) port on the IP interface.

To add an ARP entry:
:
Then verify the newly-created ARP entry using the
portShow
command:
:
Configuring an iSCSI interface
The following sections describe the steps needed to finalize iSCSI blade set up.
• ” Creating iSCSI virtual targets ” on page 117
• ” Creating discovery domains and domain sets ” on page 118
• ” Defining CHAP entries for iSCSI device authentication ” on page 120
• ” Finalizing the iSCSI configuration ” on page 120.
• ” Configuring iSCSI protocol for each iSCSI port (Optional) ” on page 121
Creating iSCSI virtual targets
An iSCSI target must be created before exposing it to the iSCSI host. You must provide the number of
Logical Unit Numbers (LUNs) and the actual LUN values that are part of the created iSCSI target. This
section describes the procedure to create an iSCSI target.
The iSCSI virtual target is created using physical Fibre Channel targets that you can access. The most
important part about creating the iSCSI virtual target is its name. The iSCSI Qualified Name (IQN) is an
