  •         No backup or ddboost replication should be running during that period or else it will get affected.     
  •    
               # ddboost file-replication show active   
sysadmin# ddboost file-replication show activeFile-replication active:  There are no file replication operations in progress.    
   
         
  •         For the HA system, verify the health of the HA configuration, run the following command in CLI:     
  •    
                # ha status   
         
  •         For HA systems, run the # ha offline command if the system is in a highly available state with both nodes online. Skip this step if the HA status is degraded.     
  •    
   
    1)  To Power off Data Domain   
   
          # system poweroff   
sysadmin# system poweroffThe 'system poweroff' command shuts down the system and turns off the power.        Are you sure? (yes|no) [no]: yes    
         Once powered off you can proceed to remove power cables from Head unit/Controller or expansion shelves if needed.   
   
     2)  To Power on the system:   
         
  •         Power on all expansion shelves before powering on the Data Domain controller. Wait approximately three minutes after all expansion shelves are turned on.     
  •      
  •         Plugin the power cord for your head unit/controller, for HA systems, power on the active node first, and then the standby node.     
  •      
  •         For HA systems, verify the health of the HA configuration, run the following command:     
  •    
               # ha status   
         
  •         For HA systems, if one of the nodes displays as offline, run the # ha online command on that node to restore the HA configuration.     
  •    
 3)  To Reboot the Data Domain using GUI   
         
  1.         Select Maintenance > System > Reboot System     
  2.      
  3.         Click OK to confirm

    4)  Procedure to reboot/ power off DD3300 using IDRAC:   
   
         Power cycle on DD3300 can be done using IDRAC by following this process:   
         
  •         Login to the IDRAC      
  •    
               By default, iDrac can be accessed using  IP: 192.168.0.120    
               User: root     
               Password: PSNT serial number on the tag in the back of the appliance (See KB 335346 to locate)   
         
  •         Once logged in, various graceful shutdown can be performed, such as:     
  •    
               1) Power Off System   
               2) Non-Masking Interrupt   
               3) Warm Reboot   
               4) Cold Reboot   
   
              User-added image   
   
                      
      The complete reboot process used for any of the systems will generally take 30 minutes to 1 hour.   
   
                                                                                                                                

 

 

Notes:

 

 

   

         
  •         Do not use the chassis power switch to power off the system. Doing so prevents remote power control using IPMI. Use the # system poweroff command instead. The system poweroff command shuts down the system and turns off the power.      
  •      
  •         The IMPI Remote System Power Down feature does not perform an orderly shutdown of the DD OS. Use this feature only if the system poweroff command is unsuccessful     
  •      
  •         After reboot, if the system takes more then 1 hour to come up please contact your support team.
