Platform Management Intel® Server Board X38ML seconds. The SDR repository cannot be accessed or modified until the erasure is complete. The SDR may only be erased while the BMC is in SDR update mode. 5.12.2 Initialization Agent The BMC implements the internal sensor initialization agent functionality specified in the Intelligent Platform Management Interface Specification, Version 2.0. When the BMC initializes or when the system boots, it scans the SDR repository and configures the IPMB devices that have management controller records and the Init Required bit set in their SDR repository. This includes setting sensor thresholds, enabling or disabling sensor event message scanning, and enabling or disabling sensor event messages. SDR Update mode does not affect the initialization agent. Any records available during the initialization agent runtime are initialized. The initialization process causes the IPMB micro-controllers to rearm their event generation. In some cases, this causes a duplicate event to be sent to the BMC. The BMC's mechanism to detect and delete duplicate events should prevent any duplicate event messages from being logged. For details on the initialization agent, refer to the IPMI 2.0 specification. 5.13 Field Replaceable Unit (FRU) Inventory Device The BMC implements the interface for logical FRU inventory devices as specified in the Intelligent Platform Management Interface Specification, Version 2.0. This functionality provides commands used for accessing and managing the FRU inventory information. These commands can be delivered through all interfaces. The BMC provides FRU device command access to its own FRU device. The FRU device ID mapping is defined in Table 32. The BMC controls the mapping of the FRU device ID to the physical device.

Applications cannot relocate or resize any FRU inventory areas. Note: Fields in the internal use area are not for OEM use. Intel reserves the right to relocate and redefine these fields without prior notification. Definition of this area is part of the software design.

Initialization Agent

The BMC implements the internal sensor initialization agent functionality specified in the

Intelligent Platform Management Interface Specification, Version 2.0.

When the BMC initializes

or when the system boots, it scans the SDR repository and configures the IPMB devices that

have management controller records and the

Init Required

bit set in their SDR repository. This

includes setting sensor thresholds, enabling or disabling sensor event message scanning, and

enabling or disabling sensor event messages.

SDR Update mode does not affect the initialization agent. Any records available during the

initialization agent runtime are initialized.

The initialization process causes the IPMB micro-controllers to rearm their event generation. In

some cases, this causes a duplicate event to be sent to the BMC. The BMC’s mechanism to

detect and delete duplicate events should prevent any duplicate event messages from being

logged. For details on the initialization agent, refer to the IPMI 2.0 specification.

BMC FRU Inventory Area Format

See the

Platform Management FRU Information Storage Definition, Version 1.0

The BMC provides only low-level access to the FRU inventory area storage. It does not validate

or interpret the data. The BMC includes the common header area. Applications cannot relocate

or resize any FRU inventory areas.

Note:

Fields in the internal use area are not for OEM use. Intel reserves the right to relocate

and redefine these fields without prior notification. Definition of this area is part of the software

design. The format in the internal use area may vary with different BMC firmware revisions.
