Hi All,
Could you please try to move the VM to other Host and try the same steps ?
If you have only a single host ....then try to restart the VMware services on the host
#service mgmt-vmware restart
Finally,
The solution is that I must close all of the VSphere 4.1 client which connects to three different VCenter. After closing them all and open just one VSphere client that I need all is good.
