Hi Brian,

If the blade is power off, it will not open the console instead of
outputting one messsage "The command 'rcons' is only support while the
blade  is in the  on state ".     That's the same when we open the console
through CMM.  Before open the console, our code will check the  blade's
state. That's also what I designed.   When admins get this message, he/she
should power on the blade .  When the blade is on, the console will be
opened automatically.

So I don't think this defect is valid.  

Actually, there is another problem.  at the beginning,  the blade is on,
and we open the console well. and then we power off the blade, and then
power it on. at that time, we open the console,  some errors will come out.
We need to reconnect the connections in this situation.  And Er Tao is
working on.

Thanks.

Er  Tao,   John,    
I asked  Grace to open this bug to track this as a documentation/design 
issue. 
I told her that she will need to rpower  <blade>  on   before  executing
the rcons
command to the blade as the work around . 
 
Since we are using the  "blade"  to be used  for CEC/blade properties, we
need 
to have the  "blade" CEC  powered up so that  rcons  can be used .  
If the  blade is powered off   the rcons  returns  the error. I think we
will need to 
document in our Wiki  that the admin should  rpower  <blade>  state  to
make sure the blades is on,  if not the admin should rpower blade on, and
check rpower blade state to be on before running the rcons <blade>   
I think that we need to document
