Set Thin Provisioning Pool-Eco-mode

This function sets the Eco-mode schedule that is specified in the "Set Eco-mode Schedule" func-              
tion in the Thin Provisioning Pool and runs the schedule.
ETERNUS DX400/DX8000 series activates the stopped disk motor according to the schedule           
specified for the Thin Provisioning Pool.

When the Eco-mode schedule is set to Thin Provisioning Pool (TPP),          
register at least one Eco-mode schedule in the device.

When the Eco-mode schedule is set to TPP, the same Eco-mode          
schedule  is  set  for  all  the  RAID  Groups  belonging  to  the  TPP.  Enabling            
or disabling the Eco-mode, or setting a different Eco-mode schedule in          
RAID Group units is not allowed.

If  the  device  status  is  changed  to  one  of  the  following  while  Eco-mode  is             
enabled (and the disk is activated), disks installed  in  the  target  TPP  will            
not deactivate the motor based on the Eco-mode settings. Eco-mode         
will be re-enabled when the interrupting process is resolved  (finished,         
etc.):

TPP includes one or more RAID Groups whose status is other than           
"Available"
