Public bug reported:
During attach volume operation, initialize_connection in Cinder is
called. If timeout happens during initialize_connection, the volume
state will be changed back to "available". However, volume could be
already mapped to the host on the array. This leaves the database and
array out of sync. If rescan happens on the host after this, the
volumes could show up as faulty devices when issuing the multipath
command.
The timeout exception during attach volume should be handled and a
rollback should be triggered by calling terminate_connection in Cinder.
