I posted a similar question previously but not this specific question. Maintenance mode timeout and retries
I am looking for suggestions on the following:
VM appliance that takes longer than 300 seconds to shutdown and allow the host to enter Maintenance Mode. This is legitimate. It sometimes takes the application longer to clean everything up and shutdown and cannot be sped up.
The VM cannot be migrated. It needs to be on specific hosts.
I know the command line will allow me to specify a timeout but I am hoping there is a way to change the default or perhaps delay the start of maintenance mode so that it doesn't timeout and fail. When this happens it creates a series of problems for some custom HCI software.
Can the timeout value be changed in code somewhere? That way customers can still use vsphere and not command line.
Not all customers have access to vRA\vRO or other automation tools so I am looking for some native solution for now. I feel the answer is basically no from the research I have done but hoping for something that will work.
Thank you
