cucsProcessorErrorStatsSparingErrors2WeeksH is a read-only Gauge32 on the processor's ErrorStats object, a companion figure kept alongside the base sparingErrors2Weeks counter and covering the same errors tied to memory rank sparing, the RAS feature that swaps in a spare DIMM rank when one starts failing over the same rolling two-week window. An admin watching this CPU cares because a climbing count here points at memory rank sparing degrading, which is exactly the kind of silent memory-subsystem fault that precedes an uncorrectable error or a forced DIMM/processor replacement. For example, if memory rank sparing on a blade's processor starts logging a nonzero and rising value here week over week, an admin would schedule that blade for a memory reseat or RMA before the errors escalate to a crash.
