I have had this question multiple times now, how do I disable datastore heartbeating? Personally, I don’t know why you would ever want to do this… but as multiple people have asked I figured I would write it down. There is no “disable” button unfortunately, but there is a work-around. Below are the steps you need to take to disable datastore heartbeating.
vSphere Client:
- Right Cluster object
- Click “Edit Settings”
- Click “Datastore Heartbeating”
- Click “Select only from my preferred datastores”
- Do not select any datastores
Web Client:
- Click “Cluster object”
- Click “Manage” tab
- Click “vSphere HA”
- Click “Edit button” on the right side
- Click “Datastore Heartbeating”
- Click “Select only from my preferred datastores”
- Do not select any datastores
It is as simple as that… However, let me stress that this is not something that I would recommend doing. Only when you are troubleshooting and need it disabled for whatever reason, please make sure to enable it when you are done.
