I have a Dell server with a 1G dual port iSCSI adapter. I have installed the NIC driver and using Microsoft iSCSI initiator, map few luns to both the ports and enable MPIO. The target I used was Microsoft iSCSI Software target. In MPIO, I set the policy as Round robin.
Now, I use IOMeter to start IO on all the luns. WHile the IO is running, I pull one cable from a port. Now, what I see is that IO stops on the connected port as well and then resumes after 30 seconds.
My question here is, since Round robin policy is a load balancing policy, why does the IO pause for 30 seconds on the connected port? Is it possible to eliminate the 30 second period entirely?
