Speaking of SAN's, has anyone gotten the multipath feature in SL42 to work? We have an IBM blade equipped with a dual-port Qlogic controller connected through two independent fabrics to a DS400/Adaptec array with a dual-port controller. fdisk -l shows two paths to every logical array, ie. each disk shows up twice. The instructions make it look easy (comment everything out from /etc/multipath.conf, start up multipathd and away you go). Running multipath -v2 -l shows nothing. multipath -v3 shows that it sees all of the devices but I don't know how to decipher where it is going wrong (I'd attach the output but I'm typing this from home).
