vdsm and backend logs

Versions:
Red Hat Enterprise Linux Server release 6.2 (Santiago)
vdsm-4.9-112.1.el6.x86_64

Scenario (reproduction steps):
1. Add lun to an existing storage server on Data Center with at least 2 hosts.
2. The backend sends connectStorageServer to the HSM which returns successfully, then sends it sends immediately getDevicesVisibility which returns with False since multipath didn't have the time to map the new lun, hence the backend sends disconnectStorageServer.

From vdsm log:
