DataDomain - Upgrade by command line

Issue
Today I had to update the firmware of a DataDomain 3300 to the latest version 7.1.0.10-646016, however, there is an issue that prevents you from updating from the GUI ...

Solution

1. First of all we should download locally the firmware .rpm file from the DellEMC support site. In our case we have to download the 7.1.0.10-646016.rpm file.
   
   
2. Then we must copy the .rpm file into a specific path "/ddr/var/releases".
   
   scp 7.1.0.10-646016.rpm sysadmin@dd3300:/ddr/var/releases/
   
   
3. Got access the Data Domain appliance via SSH, we proceed giving the pre-check command ...
   
   sysadmin@dd3300# system upgrade precheck 7.1.0.10-646016.rpm
   
   
4. If no issues were found, we go ahead starting the upgrade ...
   
   sysadmin@dd3300# system upgrade start 7.1.0.10-646016.rpm
   
   and then typing "yes" and enter.
   
   
   
   
   
5. System will reboot automatically...
   
   
   
   
   
6. When the appliance become reachable again, gained access by ssh, we can check the status of the upgrade with the command ..
   
   sysadmin@dd3300# system upgrade status
   
   
   
   
   To be sure that the upgrade is completed successfully, we have to wait the message (as shown below in the picture):
   Current Upgrade Status: DD OS upgrade Succeeded
   
   
   
   
   
   
7. We can now get access to the DataDomain Appliance by the GUI
   
   
   

That's it.
