Stopping a Single Node


You can stop any single node in the cluster to perform maintenance without affecting the integrity of the cluster (because the server’s redundant partner takes on the primary role). These commands just stop the node’s process—they have no effect on the system itself, which may still need to be shut down.

If the node is a SBR node, modifying configuration files often requires a restart.

The stop commands for each type of node are as follows:

SBR nodes (s):

sbrd stop radius

SBR/management nodes (sm) (in the following order):

sbrd stop radius

sbrd stop ssr

Management nodes (m) and data nodes (d):

sbrd stop ssr
