L2: Reproduction of problem isolation - technical support designed to duplicate customer problems, isolate problem areas and potential issues, and provide resolution for problems not resolved by Level 1 Support.
L3: Code Debugging and problem resolution - technical support designed to resolve complex problems by engaging engineering in patch provision, resolution of product defects which have been identified by Level 2 Support.

5 High-Availability Tools #
5.1 Geo Cluster Bootstrap Commands #
In the past, configuring a geo cluster was more complicated than configuring the base cluster, as there were no bootstrap commands to help with configuration.
With SLE HA 12 SP3, crmsh now has additional commands
that help configure a geo cluster: geo-init,
geo-init-arbitrator, and geo-join.
