In cinder.conf, I am using

iscsi_helper=ietadm

The interesting fact here is create is working, but not delete. Also the
following command(hiding the credentials),

sudo cinder-rootwrap /etc/cinder/rootwrap.conf iscli deletevdev -s ******
-u root -p ****** -v `iscli getvdevlist -s ****** -u root -p ****** | grep
volume-123ff5b0-ff3d-43ea-b3b0-0d84 | awk '{ print $2 }'`

if run from terminal works fine. Any pointers on this are much appreciated
