SUM same system_id UTM does not connect

Question

Hi, 
 i am troubleshooting a problem with our SUM Gateway and 2 of our 5 UTMs. 
 These 2 UTMs won&acute;t connect together to the SUM because they have the same system_id. I tried to change or reset the id with 
 cc reset_system_id but they got no new id. They have always the same id. Reboot, nothing helps. So, only 1 UTM could connect simultaneously. What can i do? Only a reset of one UTM? What is with backup? Does it restore the system_id as well? Or is there a way to change the system_id? Thx Bj&ouml;rn

Hey Bjoern. 
 When I had this kind of issue, I SSH'd into the device and manually changed the content of /etc/guid. Just change some numbers and letters. Then run 
 cc reset_system_id 
 and reboot. 
 That did it for me.
