Do not use the Add/Remove Software option in the YaST Control Center to install additional OES products. Instead, select the option specific to the service you want to add.
For example, if you want to add NetStorage as a service on an OES Linux server, the option to use is Network Service > NetStorage. This option not only installs all the required packages, but lets you configure the service as well.
For more information on the location of service-specific options in the YaST Control Center, see OES Linux Installation Guide .
