System Event Log Messages for IPMI Systems 41
Memory ECC Events
The memory ECC event messages monitor the memory modules in a system. These messages monitor
the ECC memory correction rate and the type of memory events that occurred.
< Entity Name > PS Redundancy sensor
redundancy degraded.
Information Power supply redundancy is degraded if one
of the power supply sources is removed
or failed.
<
Entity Name > PS Redundancy sensor
redundancy lost.
Critical Power supply redundancy is lost if only one
power supply is functional.
<
Entity Name > PS Redundancy sensor
redundancy regained.
Information This event is generated if the power supply
has been reconnected or replaced.
Table 3-6. Memory ECC Events
Event Message Severity Cause
ECC error correction detected on
Bank # DIMM [A/B].
Information This event is generated when there is a
memory error correction on a particular Dual
Inline Memory Module (DIMM).
ECC uncorrectable error detected on
Bank # [DIMM].
Critical This event is generated when the chipset is
unable to correct the memory errors. Usually,
a bank number is provided and DIMM may
or may not be identifiable, depending on
the error.
Correctable memory error logging
disabled.
Critical This event is generated when the chipset in
the ECC error correction rate exceeds a
predefined limit.
