Re: DM Multipath
echo "- - -" > /sys/class/scsi_host/host1/scan
Where 'host0' is the first fiber card, 'host1' is the second, etc.
Make sure to have a 'tail -f' going on /var/log/messages when you run the command so you can spot possible issues.
If a redetect doesn't work, I'd suggest a reboot, unfortunately.
Hope this helps.
