If using VMware in an HA cluster configuration, after stopping the virtual server and switching it to maintenance mode, it is necessary to shut down the ESX Server.
However, there is a possibility of system complications if there is a power outage, as this operation cannot be performed.
As an example of the system complications, the ESX Server cannot be managed, the VMware HA configuration is corrupted and has to be restarted etc., and the length of time it takes to return to operation increases.
If using the VMware HA operation management template in Systemwalker Runbook Automation, it automatically shuts down the virtual server if there is a power outage, and switches it to maintenance mode, and the ESX Server can be shut down. By this means, it is possible to avoid a VMware HA configuration crash.
The purpose of the VMware HA operation management template is to shut down the ESX Server in an appropriate order in an environment that has introduced Systemwalker Runbook Automation and is using VMware in an HA Cluster configuration.
