Information

Please have the following information available:

• Hostname of the machine
• Running kernel (you can obtain it running uname -a)
• A specific problem description and its severity, that is, its impact on your operations
• Additional relevant information about the affected systems: attach logs and error messages.
• It is not unlikely that Linux Support will ask you to get access to the machine, in that case:
