I'm assuming your using the default LVM storage back-end. Something to look at: "sudo tgtadm --lld iscsi --op show --mode target" - Make sure your target is present (on the cinder node) You shouldn't *need* to do this, but to trouble-shoot you could also try: "sudo iscsiadm -m discovery -p 192.168.150.96:3260 -t st" followed by trying to login. "sudo iscsiadm -m node -T iqn.2010-10.org.openstack:volume-3ac4b027-905e-4318-a74e-2bdf94f5d887 -l" John
