I got this error / warning in all of my ESX 4.1 433742 hosts after I have successfully upgraded the VCenter 5.1u1
The number of vSphere HA heartbeat datastores for this host is 1 which is
less than required 2
What should I do to fix that issue as per this article: http://www.yellow-bricks.com/2012/04/05/the-number-of-vsphere-ha-heartbeat-datastores-for-this-host-is-1-which-is-less-than-required-2/
should I put check box in that one and only data store ?
I don't want to create any unwanted downtime by any chance.
