A Redis Software cluster contains a primary node, which coordinates cluster-wide management operations, and multiple secondary nodes. Nodes with either role can host database shards.
Demote primary node
To demote the primary node to a secondary node using the Cluster Manager UI:
-
On the Nodes screen, click the More actions button (⋮) for the primary node you want to demote.
-
Select Set as a secondary node from the list.
-
Select one of the options to determine the new primary node:
-
Automatically: The cluster decides which node becomes the new primary node.
-
Choose specific node: You can manually select which node becomes the new primary node.
-
-
Click Confirm.
Promote secondary node
To promote a secondary node to become the primary node using the Cluster Manager UI:
-
On the Nodes screen, click the More actions button (⋮) for the secondary node you want to promote.
-
Select Set as the primary node from the list.
-
Click Confirm.
After this node becomes the primary node, all cluster management traffic is directed to it.
