Verifying Platform Requirements
The Vertica installer checks the target platform as it runs, and stops whenever it determines the platform fails to meet an installation requirement. Before you update the server package on your systems, manually verify that your platform meets all hardware and software requirements (see Platform Requirements and Recommendations).
By default, the installer stops on all warnings. You can configure the level where the installer stops installation, through the installation parameter
--failure-threshold. If you set the failure threshold to
FAIL, the installer ignores warnings and stops only on failures.
Changing the failure threshold lets you immediately upgrade and bring up the Vertica database. However, Vertica cannot fully optimize performance until you correct all warnings.
