When you use multiple remote connections, you should prepare as many quorum disks as remote connections to avoid the possibility of a single remote connection failure causing the suspension of the GAD pairs that are using the other normal remote connections.
Simultaneously, you must make a combination of one quorum disk, one remote connection from the primary storage system to the secondary storage system, and one remote connection from the secondary storage system to the primary storage system.
When all paths used in the remote connection are blocked, the GAD pairs will be suspended in units of quorum disks. In the configuration shown below, the GAD pairs that are using remote connection 1 will be suspended even if the failure occurred at remote connection 2. Also, when a failure occurs at the path from the volume at the primary site or the secondary site to the quorum disk, the GAD pairs that are using the same quorum disk will be suspended.
