Quiescing a node by using immediate drain

On a high availability system, you can remove a node from a pool of active nodes by quiescing the node from the high availability landing page. The default quiesce method is immediate drain, which does not require removing the nodes from the load balancer before starting the quiesce process. If you choose to use the slow drain method, you must remove nodes from the load balancer first.

To quiesce a node from the high availability landing page, perform the following steps:
  1. Identify the Pega Platform node or nodes that you want to quiesce.
  2. Click Configure > System > High Availability > HA Cluster Management.
  3. Select the check box next to the node or nodes that you want to quiesce.
  4. Click Quiesce. When the quiesce process is complete, the status of the node changes into Quiesce Complete in the Runstate column on the HA Cluster Management landing page.
  5. To prevent traffic from being directed to the quiesced node or nodes, configure the load balancer to remove the quiecsed node or nodes from the pool.
    Note: To cancel the quiesce process for the selected node or nodes, click Cancel Quiesce.
