* we use setup_iscsi_client.py to deploy iscsi client services, configuring intiator and mulitpath this is done by qa task ceph_iscsi_client * qa/cephadm: adds remotes ip addresses to iscsi gateway, * rename poolname: iscsi >> datapool, which we usually use for tests and expresses type of pool more clearly.
