The Reliability/Availability/Serviceability (RAS) strategy for S/390® G5 and G6 is to continue the S/390 objective of providing Continuous Reliable Operation (CRO). The RAS strategy is constructed with a set of building blocks which work closely together: error prevention, error detection, error recovery, problem determination, service structure, change management, and RAS measurement and analysis. The interdependency among the building blocks is such that removing or weakening any of them limits the ability of the design to achieve the overall CRO objective. Each building block must be fully implemented and must execute flawlessly within itself and together with the other blocks.
