I'm in the middle of upgrading my environment from 4.1 to 5.1.
I have upgraded vCenter and about half of my blades
I'm running 28 installations of vmware on 2 IBM bladecenters.
My 4.1 environment has been pretty bulletproof but so far I can't say the same for 5.1
This occurs intermittently and has happened to at least 6 of my hosts (5.1.0 Build 1065491).
I keep encountering a scenario where the host disconnects.
The guests show disconnected also although they are still functional.
The ESXi console will let me enter the username and password but freezes and never actually enters the hypervisor.
Since the guests are powered on and owned by an otherwise functioning host, I cannot remove them and add them to another host.
The only solution I have found is to reboot the host, which also reboots the vms.. Obviously this is unacceptable..
Does anyone have any suggestions?
