 The value could be B<lpar> or B<fnm>. The tooltype value B<lpar> is for xCAT and B<fnm> is for CNM. The default value is "B<lpar>". For cold start in the large cluster, it will save a lot of time if the admins use "B<rpower> I<noderange> B<onstandby> B<-T> B<fnm>" to power on all the CECs from the management node through the B<fnm> connections.

-Turn CEC to low power state (state EOCT). This is a disruptive operation which requires the CEC to be powered off prior to entering low power mode. And we can use power off command to get out of lowepower state.

 Places the rack in the rack standby state. It requires that all CECs and DE be powered off before it will run.
