Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/cinder" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    VNX: allow specify pool name for replication

    Currently, VNX driver will select a pool of same name as the
    source volume when creating LUN replication. An error will occur if not
    satisfied.
    This patch will allow setting a different pool name for replication
    target instead of using the pool of same name on the remote system.

Technically, confirmed for openstack-manuals, but as http://lists.openstack.org/pipermail/openstack-dev/2017-June/118055.html is implemented, the origin of this content will change.
