For some reason, after I was working on setting up VMWare ESXi 5.5 on my own server. It worked for a week without any problem and then, I ran into the error on screen as below :
"no coredump target has been configured. host core dumps cannot be saved."
I really don't know what should I do with that and why it happened. Tried to google and found many websites refer to this link -> Configuring a diagnostic coredump partition on an ESXi 5.x/6.0 host (2004299)
The question here is do I really need to create a partition for this purpose? If I need it, it should be there already since it works without that error for a week before. I really confused until I found another article here ->
Configuring ESXi coredump to file instead of partition (2077516)
"Configuring ESXi coredump to file instead of partition (2077516)" is a lot easier and I don't really need to do anything with partition at all. Tested and it works.
