How to change the hostname on the GroupWise Mobility Server

How to change the hostname on GMS 2 server

Since most of the passwords are encrypted on GroupWise Mobility Server 2.0 using the hostname, it is important to follow the steps listed below to change the password.

1. Make a backup copy of GMS settings by typing
   cp /etc/datasync /etc/datasyncbak -v -R -p
2. Make note of the current hostname by typing
   hostname -f
3. Launch YaST | Network Devices | Network Settings | Hostname/DNS and set the Hostname and Domain Name properly
4. Save the Changes
5. Reconfigure the GMS encryption by following TID 7015744, with the hostname from step 2
   
6. Restart GMS to make sure it comes up without a problem by typing rcgms restart and login to GMS webadmin
7. Restart the Server by typing init 6 and press Enter
