22.9 System Event Log (SEL)
The BMC implements the system event log as specified in the Intelligent Platform Management
Interface Specification, Version 2.0. The SEL is accessible regardless of the system power state
via the BMC's in-band and out-of-band interfaces.
The BMC allocates 65,536 bytes (64 KB) of non-volatile storage space to store system events.
Each record is padded with a four-byte timestamp that indicates when the record was created,
making each SEL record 20 bytes in size. The SEL timestamps might not be in order. Up to
3,276 SEL records can be stored at a time. An attempt to add records beyond the maximum
results in a failure and the out-of-space completion code is returned.
22.9.1 Servicing Events
Events can be received while the SEL is being cleared. The BMC implements an event
message queue to avoid the loss of messages. Up to three messages can be queued before
messages are overwritten.
The BMC recognizes duplicate event messages by comparing sequence numbers and the
message source. See the IPMI 2.0 specification. Duplicate event messages are discarded
(filtered) by the BMC after they are read from the event message queue. This means the queue
can contain duplicate messages.
22.9.2 SEL Entry Deletion
The Delete SEL command does not reclaim deleted SEL record space, but marks the records
so they are not seen by the IPMI Get SEL Entry command. The BMC implements the Get All
SEL Entry extension command that lists all SEL records, including those that have been deleted
by the Delete SEL command. SEL erasure is the only way to reclaim SEL record space.
The Get All SEL Entry is an OEM-command and assumes a particular SEL implementation. If a
software application that accesses the SEL is required to be IPMI compatible (it is expected to
work with any IPMI-compliant platform), then this command should not be used.
22.9.3 SEL Erasure
SEL erasure is a background process. After initiating erasure with the Clear SEL command,
additional Clear SEL commands must be executed to get the erasure status and determine
when the SEL erasure is completed. This may take several seconds. SEL events that arrive
during the erasure process are queued until the erasure is complete and then committed to the
SEL.
SEL erasure generates an Event Logging Disabled (Log Area Reset / Cleared offset) sensor
event. The BMC generates Event Logging Disable to indicate the SEL area has been erased.
22.10 Sensor Data Record (SDR) Repository
The BMC implements the sensor data record (SDR) repository as specified in the Intelligent
Platform Management Interface Specification, Version 2.0. The SDR is accessible through the
BMC’s in-band and out-of-band interfaces regardless of the system power state The BMC
