8. Correctable Error Threshold
Option Values:
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:
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.
When Rank Sparing RAS Mode is configured, "All" and "None" are not valid, so they will not be
presented as choices.
This threshold is applied on a per-rank basis. The Correctable Error occurrences are counted for
each memory rank. When any one rank accumulates a CE count equal to the CE Threshold, then
a single CE SEL Event is logged, and all further CE logging is suppressed.
Note that the CE counts are subject to a "leaky bucket" mechanism that reduces the count as a
function of time, to keep from accumulating counts unnecessarily over the term of a long
operational run.
This is also the Correctable Error threshold used when Rank Sparing RAS Mode is configured.
When a CE threshold crossing occurs in Rank Sparing Mode on a channel which is in Redundant
state, it causes a Sparing Fail Over (SFO) event to occur. That threshold crossing will also be
logged as a Correctable Error event if it is the first to occur on the system.
An SFO event causes the rank with the error to be replaced by the spare rank for that channel, and
the channel goes to a non-redundant state (with a "Redundancy Degraded" SEL Event logged).
There may be an SFO for each channel in the system, although only the first one can be logged as
a CE event.
