Looking for help kind of in a hurry. I've been searching google but not finding any options. Is there any way to fix missing /dev paths to luns without rebooting? For example, see the output from lsscsi below. The only way I know to fix this is with a reboot, but I REALLY Need to avoid that if possible.

I used it to add new disks to a VM without a reboot. http://www.cyberciti.biz/tips/vmware-add-a-new-hard-disk-without-rebooting-guest.html echo "- - -" > /sys/class/scsi_host/host#/scan fdisk -l tail -f /var/log/message is the relevant piece. note where it says 'host#' you'll need to find the host number (all mine had 0,1,2); I can't swear this won't make your host catch on fire, burn to the ground, return as a zombie and write bad checks in your name, but it seemed to work for me. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
