17.3.2 Timing for node switching
Implement the node switching at the following timing:
-
When the cluster software detects node failure# such as hardware failure
-
When the process being monitored (Administration Agent or Management Server) is down
-
When the node switching command of the cluster software is used
-
When other events in which the cluster software switches the node occur
- #
-
Indicates failure occurring in nodes except the servers. This includes hardware failure in nodes and cluster software failure.
