Comment 10 for bug 1732199

On further inspection, iscsiadm is actually returning 0 (success) - it's just the stderr output that's tripping up os-brick, at:

https://github.com/openstack/os-brick/blob/master/os_brick/initiator/connectors/iscsi.py#L120-L123

which produces:

Sep 24 10:55:26.759691 ubuntu-xenial-rax-ord-0002235107 nova-compute[15157]: WARNING os_brick.initiator.connectors.iscsi [req-eb1112fc-2010-4878-b6ed-7bd6d5c65b82 req-118f3f55-90c0-47b4-98c9-9b8069625dce service nova] Couldn't find iscsi sessions because iscsiadm err: iscsiadm: could not read session targetname: 5

Maybe it should be looking at the exit code instead of the stderr text (maybe just log it as a warning and move on?)...
