Part VI Troubleshooting #

SUSE® Linux Enterprise Server comes with several sources of information and documentation, available online or integrated into your installed system.

For a quick overview of all relevant system information of a machine, SUSE Linux Enterprise Server offers the hostinfo package. It also helps system administrators to check for tainted kernels (that are not supported) or any third-party packages installed on a machine.

In case of problems, a detailed system report may be created with either the supportconfig command line tool or the YaST Support module. Both collect information about the system such as: current kernel version, hardware, installed packages, partition setup, and much more. The result is a TAR archive of files. After opening a Service Request (SR), you can upload the TAR archive to Global Technical Support. It helps to locate the issue you reported and to assist you in solving the problem.

Additionally, you can analyze the supportconfig output for known issues to help resolve problems faster. For this purpose, SUSE Linux Enterprise Server provides both an appliance and a command line tool for Supportconfig Analysis (SCA).

This chapter describes a range of potential problems and their solutions. Even if your situation is not precisely listed, there may be one similar enough to offer hints to the solution of your problem.
