Public bug reported:

*Descriprtion*
When a volume is being attached to an instance, the compute transfers the host ports to the storage driver through cinder inside the initialize_connection call. The compute will only pass online ports and will not report any ports that are down (linkdown).

*Issue*
If a port that was down at the attach time, comes up afterwards, or ports were physically added at some points, there is no update mechanism to inform the storage driver about them so the driver will be able to utilize them.

*Solution*
There should be an update mechanism that runs periodically and reports host changes to the driver through cinder.
