Hello Babu. Thanks for responding.

Yes. I have assigned 1 LUN to each of the controllers.

I changed to "failback manual" in /etc/multipath.conf and rebooted. I'm 
not sure if the reboot was necessary or not. This does not appear to 
have changed the behavior.

There are no "MODE_SELECT" messages in syslog. Would these be appearing 
elsewhere? The syslog from the last reboot up until I started receiving 
the "Illegal Request" messages is available here http://tinypaste.com/f7f413
