SUSE® Linux Enterprise Server comes with various sources of information and documentation, many of which are already 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
module. Both will 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 will help 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 here, there may be one similar enough to offer hints to the solution of your problem.
