Symptoms

In an Active-Active deployment for OCSC, when OCSC1 has problem with hardware failure, OCSC2 can not handle traffic, either, only after a restart of OCSC2, it works.

The hardware failure: Disk array is there but the disk array controller failed. When the failure happened, ping OCSC1 still worked, but ssh to OCSC1 failed.

Expected Behavior
-----------------------
In Active-Active deployment, when one node is down, the other node should not be infected.


Scenario
-----------------------
1, OCSC1, OCSC2 worked normally

2, OCSC1 had disk failure, but ping still worked, traffic to OCSC1 failed

3, OCSC2 was infected by OCSC1, all the call to OCSC2 failed

4, Restart OCSC2, OCSC2 recovered, 1/2 call successful.

5, Unplug OCSC1 cable, almost all the call successful.
