To successfully integrate with GroupWise, you need to install but not configure the GroupWise server software for your version of GroupWise on the GWDR server. GWDR requires the GroupWise server software to be installed on the server to be able to copy the database files during a backup and run a POA during disaster recovery mode. Before installing the GroupWise server software, make sure the following is installed on your GWDR server:
Motif (This can be installed through YaST > Software Mangement).
(Optional) If installing on SLES 12 or 15, install rpm-32bit from YaST as well.
After you have these installed on your server, install the GroupWise server software and then continue with Installing GroupWise Disaster Recovery.
