From: Peter Oberparleiter <peter.oberparleiter@xxxxxxxxxx>
Path verification events occurring for offline devices are currently
ignored. As a result, offline devices are not removed, even though
they might no longer be accessible (for example because the last path
to the device was varied offline). Fix this by scheduling a status
evaluation for the affected subchannel when a path verification event
occurs.
