Start / StopCommand is not issued to the resources with Unknown state, during start / stop of resource group or takeover.
"StartCommand / StopCommand is not issued to the resources with Unknown state, during starting / stopping of resource group or takeover"
This request comes from the PMR - 04264,616,760 The request is for a change to issue StartCommand / StopCommand to Unknown resources during the start / stop of a resource group or takeover.
At high workload on the system, Unknown will likely to occur due to a time-out of the MoniorCommand and also likely to cause a takeover. Especially at the time of takeover, if stop command is not issued to the Unknown resources, the resources will run on both systems, which may cause for example, damage to the file system is mounted. The TSA policy that TSA does not cause any action to the Unknown resources is no problem if system is running normally, care is needed during takeover.
Because there is a risk of damage when critical resource runs at the same time in both systems, we usually include a command to force shutdown of the resource in the StopCommand to avoid the risk. Therefore issuing a StopCommand even for Unknown resources would be able to protect critical resources.
