Members
Signature
The signature of the error record. This member contains the value 'REPC'.
Revision
A WHEA_REVISION union that describes the revision level of the WHEA_ERROR_RECORD_HEADER structure.
SignatureEnd
The end of the signature of the error record. This member contains the value 0xFFFFFFFF.
SectionCount
The number of sections of error information that are contained in the error record.
Severity
A WHEA_ERROR_SEVERITY-typed value that indicates the severity of the error condition described by the error record.
ValidBits
A WHEA_ERROR_RECORD_HEADER_VALIDBITS union that specifies which members of the WHEA_ERROR_RECORD_HEADER structure contain valid data.
Length
The length, in bytes, of the error record.
Timestamp
A WHEA_TIMESTAMP union that indicates the time that the error was reported to the operating system. This member contains valid data only if the ValidBits.Timestamp bit is set.
PlatformId
A GUID that identifies the platform on which the hardware error occurred. This member contains valid data only if the ValidBits.PlatformId bit is set.
PartitionId
A GUID that identifies the partition on which the hardware error occurred. This member contains valid data only if the ValidBits.PartitionId bit is set.
CreatorId
A GUID that identifies the entity that created the error record. When the Windows kernel creates an error record, it sets this member to WHEA_RECORD_CREATOR_GUID.
NotifyType
A GUID that identifies the notification mechanism by which an error condition is reported to the operating system. The following are the GUIDs for the standard notification types:
CMC_NOTIFY_TYPE_GUID
Corrected Machine Check (CMC)
CPE_NOTIFY_TYPE_GUID
Corrected Platform Error (CPE)
MCE_NOTIFY_TYPE_GUID
Machine Check Exception (MCE)
PCIe_NOTIFY_TYPE_GUID
PCI Express (PCIe) Error
INIT_NOTIFY_TYPE_GUID
INIT Error Record (INIT)
NMI_NOTIFY_TYPE_GUID
Nonmaskable Interrupt (NMI)
BOOT_NOTIFY_TYPE_GUID
Boot Error Record (BOOT)
For error notification types that do not conform to one of the standard types in the previous list, a platform-specific GUID can be defined to identify the notification mechanism. If the notification type does not correspond to any of the standard notification types or any platform-specific notification types, this member is set to GENERIC_NOTIFY_TYPE_GUID.
RecordId
The identifier of the error record. This identifier is unique only on the system that created the error record.
Flags
A WHEA_ERROR_RECORD_HEADER_FLAGS union that describes the error condition.
PersistenceInfo
A WHEA_PERSISTENCE_INFO union that is used by the error record persistence interface.
OsBuildNumber
Reserved2[8]
Reserved[12]
Reserved for system use.
Remarks
A WHEA_ERROR_RECORD_HEADER structure is contained within the WHEA_ERROR_RECORD structure. The WHEA_ERROR_RECORD_HEADER structure describes general information about the hardware error condition that is described by the error record.
