Replace a Node Using an Active Standby Node
Note: A node must be down for Vertica before you can replace it with an active standby node. If you attempt to replace a functioning node, Vertica displays an error message.
Replacing a Node with Automatic Failover
Vertica can automatically replace a failed node with an active standby node. In the General Parameters configure the FailoverToStandbyAfter
parameter to allow automatic failover.
Manually Replacing a Node
