When you need to perform tasks such as configuration changes, patch application, and hardware parts replacement that may require restarting, there are two ways of node maintenance. Performing maintenance on both nodes by stopping both active and standby nodes, and performing maintenance on one node at a time by leaving the active node running to perform maintenance on the standby node first, and then switch the active node to perform maintenance on the other node. In this section, the former is referred to as simultaneous stopped node maintenance, whereas the latter is referred to as mutual switch maintenance.
Refer to the tasks outlined below in either "Figure 3.1 Workflow for simultaneous stopped node maintenance" or "Figure 3.2 Workflow for mutual switch maintenance", and perform your maintenance tasks accordingly.
