This allows you to check the disk status for options such as Fault Tolerance or Microsoft Cluster Services.  The disks must be in an Eagerzerothick format for these options to work.

At this time, there is no official fix, however it appears a reboot should fix the issue but with the Host disconnected from vCenter; vMotion is not an option and the disconnect may trigger HA, but I would hope that you have placed this host into Maintenance Mode prior to disconnecting from vCenter…right?  Also, HA should have been disabled prior to your Update 1 patch…you did that as well, right?
