4.
Perform discovery again from the host to one iSCSI ports on each of the router blades. Ensure
that the iSCSI presented target is listed on the Target's property page of the Microsoft iSCSI
initiator.
5.
From Blade 1, log in or connect to the presented target.
6.
Select the Enable multi-path option, and then verify that two paths are visible for the LUN.
Because the default load balancing policy for the Microsoft iSCSI initiator is round robin,
traffic is distributed between the direct path and the blade 1 path.
7.
Disconnect or log out from the direct path.
The I/Os should fail over from the direct path to the Blade1 path.
8.
Using Iometer, verify that the I/Os have not stopped.
9.
Issue the show perf byte command, see
to ensure that blade1
I/Os are going through the router.
10. From Blade 2, log in or connect to the presented target. The traffic should now be evenly
divided between Blade1 and Blade2.
