Figure 28 Example of a 4x4x4 Delta Resync configuration
By performing a Delta Resync when the operation site is changed from the primary site to the local
site because of a host failure at the primary site or for other reasons, the configuration is switched
to a 4x4x4 Delta Resync configuration with the local site as the origin in a short time. As a result,
operation can be continued.
The following figure shows a configuration example after a failover during a host failure at the
primary site.
