Do you see the disks ? (doing a lsscsi would show it). I guess not.
If not, you need to probe/hotplug the disks first
ho,
# echo "- - -" > /sys/class/scsi_host/host${host_no}/scan
## the three -'s are for wildcards for channel, id and LUN.
If you don't know the "host_no", do it on for all the hosts under
scsi_host, it will not harm anything.
If you have multipathd running when you run the "echo" above you would
see all the dm devices when it completes (or soon thereafter).
You don't need to reboot the server.
