Applies to Models: WRN-816S and WRN-1632(S)

Summary

Due to the nature of the WRN series recorder running Linux, in some cases, such as losing the administrator password, you may need to re-image the operating system. If Hanwha Vision releases any updates for this model recorder, they will be through an ISO that has the drivers and updates contained within that ISO. This would necessitate a re-image of the Linux OS on this recorder. This article walks you through the process to accomplish this update. 

NOTE: If you need to update the WAVE VMS server or client software version, 
there is no need to perform a re-image. 
Refer to WAVE: How do I update the WAVE VMS software? for information on 
updating the VMS. Refer to the WAVEVMS web site to download and manually 
install the Linux packages. 

WARNING: You need a blank 8GB or larger USB drive to perform this process.  
If you use a smaller drive, the process will fail with an error. This process 
will reformat your USB drive and erase all the data stored on it. We recommend 
using a brand new USB drive for this process. If a new USB drive is 
unavailable, copy off all data from the drive before performing these steps.

Reimaging a WAVE Recorder

To re-image a WRN series WAVE recorder:

1. Connect a USB keyboard and mouse to the WRN unit.
   

   NOTE: The initial stages of re-imaging require a physical keyboard. 
   On-screen keyboards are not available in the re-image process.

2. Back up your WAVE configuration, if possible.
   

   NOTE: Even though you might be locked out of the WRN Linux desktop, 
   in some cases, if you can log into the WAVE system from a client 
   workstation or the WAVE Sync website, you can backup the License keys 
   and the WAVE database.

3. Go to the Balena site and download Balena Etcher to make a bootable USB drive.
   

   NOTE: Etcher is very simple. Select your source file, your destination 
   drive, and burn the image.

4. Download the latest ISO for the WRN at WRN 816_1632 ISO Image.
   
   
5. Once the ISO is downloaded, create your bootable image using Etcher, select your source file (the downloaded ISO) and the destination drive (your USB stick). 
   
   
6. When Etcher is complete, plug the USB Drive into a blue USB 3.0 port on the rear of the WRN unit.
   
   
7. Repeatedly press Ctrl + Alt + T during WRN boot until it beeps, then enter the BIOS Boot Menu.
   
   
8. Select the USB device.
   
   
   

   NOTE: The name shown above will be different depending on the brand of the 
   USB drive.

9. Press Enter to select the first highlighted option.
   
   
   

   NOTE: Ignore the following errors.
   

   Partclone will show progress bars for the first half of the image process.
   

   NOTE: This will take roughly 5 minutes. After the progress bars are 
   complete, you will receive two warning prompts for confirmation that 
   existing files will be deleted and overwritten.

   
   
   
10. Type Y then press the Enter key to proceed with both prompts.
    
    
    
    Partclone will take roughly 5 minutes to complete.
    
    
    
    
11. Select the option to Poweroff then click OK.
    
    
    
    
12. Remove the USB drive from the WRN.
    
    
13. Download the MountDrivesOnly.sh script at the bottom of this page and place it on a USB stick.
    
    
14. Power on the unit, log in with 4321 as the password.
    
    
15. Plug in in USB stick.
    
    
16. Copy the MountDrivesOnly.sh file to the desktop.
    
    
17. After copying the file to the desktop, unplug the USB from the WRN.
    
    
18. Right click on the desktop and select Open in Terminal.
    
    
19. If you have not done so, remove the USB stick before running bash MountDrivesOnly.sh in the terminal.
    
    
20. Enter password 4321.
    
    The machine mounts the hard drives and reboots. 
    
    
21. Open the Disks application and verify that each of the storage drives in the system are mounted as /mnt/sda, /mnt/sdb, /mnt/sdc, /mnt/sdd depending on how many storage drives in the system.
    
    
    
    
22. Open Wave Client and navigate to server system settings storage.
    
    
23. Move the analytics database from the OS drive to one of the storage drives.
    
    
24. Delete the MountDrivesOnly.sh file from the desktop.

Addendum: Should WAVE not recognize the recording drive(s) in Linux upon system 
recovery, refer to the following article to properly remount them for WAVE usage:
