DB2 High Availability Instance Configuration Utility (db2haicu) maintenance mode

When you run DB2® high availability instance configuration utility (db2haicu) and there is already a cluster domain created for the current database manager instance, db2haicu operates in maintenance mode.

When db2haicu is running in maintenance mode, db2haicu presents you with a list of configuration and administration tasks that you can perform.

db2haicu maintenance tasks include adding cluster elements such as databases or cluster nodes to the cluster domain, and removing elements from the cluster domain. db2haicu maintenance tasks also include modifying the details of cluster domain elements such as the failover policy for the database manager instance.

When you run db2haicu in maintenance mode, db2haicu presents you with a list of operations you can perform on the cluster domain:
