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:.
switch:admin> portcmd --ping 8/ge0 -s 192.168.100.40 -d 192.168.100.50

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.
portcfg arp [slot/][ge]port args
To add an ARP entry:
:
switch:admin> portcfg arp 3/ge0 add 192.168.255.25 00:01:02:03:04:60
Operation Succeeded
Then verify the newly-created ARP entry using the portShow command:
:
switch:admin> portshow arp 3/ge0
Slot: 3 Port: ge0
IP Address

Configuring an iSCSI interface
The following sections describe the steps needed to finalize iSCSI blade set up.

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
