## 9.7 Scenario: Default split and merge policy 

## 9.7.1 Scenario description 

This section shows a scenario with the default split and merge policy. 

Figure 9-35 shows the topology of the default split and merge scenario.

This scenario keeps the default configuration for the split and merge policy and does not set the quarantine policy. To simulate a cluster split, break the network communication between the two PowerHA nodes, and disable the repository disk access from the PHA170 node. 

After a cluster split occurs, restore communications to generate a cluster merge  event.
