Depending on the maintenance task, perform either simultaneous stopped node maintenance or mutual switch maintenance.
Perform simultaneous stopped node maintenance if performing the following tasks:
Database recovery
Maintenance of hardware shared between the active node and standby node, such as a disk
Maintenance of hardware related to resources that are registered to the cluster service
Perform mutual switch maintenance if performing the following tasks. Mutual switch maintenance enables you to perform maintenance without stopping jobs.
Patch application
Maintenance of hardware such as CPUs or memory.
The procedures for simultaneous stopped node maintenance and mutual switch maintenance are shown below in "Maintenance workflows".
Refer to the tasks outlined below in either "Figure 5.2 Workflow for simultaneous stopped node maintenance" or "Figure 5.3 Workflow for mutual switch maintenance", and perform your maintenance tasks accordingly.
