Unfortunately there is nothing under scsi:

[root at localhost ~]# ll /sys/class/scsi_*
total 0

total 0

total 0

I also tried kudzu (http://linux.die.net/man/8/kudzu), but it still
shows only the original drive:

[root at localhost ~]# kudzu
[root at localhost ~]# kudzu -p
class: HD
detached: 0
device: vda
driver: virtio_blk
desc: "Virtio Block Device"

While looking around I found this comment (in a bug not directly related):

Hot-add is not supported for RHEV 2.1.


So maybe it actually cannot work?
