What steps will reproduce the problem?
1. set up a two onos instance cluster
2. configure three switches to backup-connected to onos instance. two switches connect to instance 1 and one switch connected to instance 2d. topology is tree.
3. pause VM one instance 2, then issue devices command on instance 1
4. after waiting for 12000 us, we saw following errors.
onos> devices

id=of:0000000000000002, available=true, role=MASTER, type=SWITCH, mfr=Nicira, Inc., hw=Open vSwitch, sw=2.0.1, serial=None
Error executing command: No response for 120000 ms. Aborting invocation! BasicInvocationFuture{invocation=BasicInvocation{ serviceName='hz:impl:mapService', op=GetOperation{}, partitionId=87, replicaIndex=0, tryCount=250, tryPauseMillis=500, invokeCount=1, callTimeout=60000, target=Address[192.168.56.102]:5701}, done=false} Not all backups have completed backups-expected:0 backups-completed: 0
5. then will see following
