ORBIT-USER: Is the grid not available?

[Xiangpeng Jing]

It seems the grid is off and nodes can not be brought up. Can not image either.
Every node reports "not available".

 Testbed : grid - Command: on
 Node n_9_12 - Error (node state: 'Not Available')
...........

Imaging errors:
(Domain:  default from hostname)
(Timeout:  800 sec.)
