You can use set instance to change certain properties for the instance. The instance must be in the Down state to use set instance. Verify status by issuing show cluster status.
Instance properties you can change are:
The log path
Arguments used for starting the instance
The primary or secondary address of the instance
The primary or secondary port range used by the instance
For example, to reset the primary port range from 6123 to 6126, enter:
set instance primary port 6123 6126
