Hi, I've got two SAS links to my San, I want to test failure/recovery by eleminating and device node. The easiest way is to manually unplug a controller link and see what happens. I'd like to know how I can do it via Linux, and then re-enable the device node? I have two device nodes /dev/sda and /dev/sdb.
