Figure 57 Communication Failure—Site 2 to Quorum Witness
Communication Failure—Site 2 to Quorum Witness and Site 1 to Site 2
In a dual-network communication failure between site 2 and the quorum witness, and between site
1 and site 2 (see Figure 58 (page 147)):
• HP 3PAR StoreServ array A reacts to the isolation of HP 3PAR StoreServ array B just as it
would react to a failure of HP 3PAR StoreServ array B. However, because HP 3PAR StoreServ
array A is already source, no action is required.
• A failover does not happen:
Host I/O continues to go to source volumes.◦
◦ Replication of I/O across remote-copy links stops.
