WAVE: Merging WRN recorders fails due to duplicate GUIDs

Applies to Models: Linux WAVE Servers, WRR, WRT, WRN

Issue Summary:
GUID duplication on Linux-based WAVE servers can block the merging of any servers. A duplicate GUID can cause WAVE Sync service disruptions on non-merged servers as well.

 NOTE: These instructions can be used for Linux WRR and WRT servers as well.

Resolution:

1. Click on the Linux version of a Start button in the lower left corner of the screen.
    

2. Enter Terminal then click on the terminal icon:
    

3. Enter: ls /usr/local/src/hit/scripts/ and press Enter.
    
      NOTE: If the script version on your device is less than version 1.03,
                  you should upgrade the OS on that WRN. The re-image instructions are
                  found in: How do I re-image a WRN series WAVE recorder?

4. Enter cat /opt/hanwha/mediaserver/etc/mediaserver.conf and press Enter.
    NOTE: Perform the "cat" command above on both servers and compare the GUID
    Example: serverGUID={985fec24-20af-6355-d06d-8e4b416261c1}
    Proceed to the next step if a duplicate GUID is discovered.

5. Enter sudo -s

6. Enter the Linux password and press Enter.
    NOTE: Password fields in Linux do not progress with spaces, this is a password
               mask, simply enter your password.

7. Enter the command: systemctl stop hanwha-mediaserver and press Enter.

8. Enter the command: nautilus to open a graphical user interface and press Enter.

9. In Nautilus, navigate to: /opt/hanwha/mediaserver/etc

10. Locate the mediaserver.conf and delete it.

11. Return to the Terminal window and enter sudo -s

12. Enter the Linux password and press Enter.

13. Enter the command: systemctl start hanwha-mediaserver and press Enter.
      NOTE: The WAVE server service will generate a new mediaserver.conf file with a random GUID to

                  allow for merging with another WRN.
