8. Correctable Error Threshold
Option Values: 20
10
5
All
None
Help Text:
Threshold value for logging Correctable Errors (CE) – Threshold of 10 (default) logs 10th CE,
"All" logs every CE and “None”’ means no CE logging. All and None are not valid with Rank
Sparing.
Comments: Specifies how many Correctable Errors must occur before triggering the logging
of a SEL Correctable Error Event. Only the first threshold crossing is logged, unless “All” is selected.
“All” causes every CE that occurs to be logged. “None” suppresses CE logging completely.
