db_suspend_nodes

This job suspends the given nodes in the given database. Suspending a node means that the node is marked as unavailable, even though it continues to run. This can be used to perform maintenance on a node. If this is done to an active node while the database is running, the database will shutdown and restart with a reserve node instead (if configured).
