Hitachi G1000 - Suspended Pairs Depending on Failure Location (Quorum Disk Not Shared); Suspended Pairs Depending on Failure Location (Shared Quorum Disk)

Tip: If you are planning to manage many GAD pairs using one quorum disk,
if more than 8 physical paths are necessary for the remote connection, you
can configure the system with one quorum disk for two or more remote
connections.
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.
