Handling of Parity Errors (PERR)

Handling of Parity Errors (PERR)

This section lists facts and considerations about how the server handles parity errors (PERR).

■The handling of parity errors works through NMIs.

■During BIOS POST, the NMI is logged in the DMI and the SP SEL. See the following example command and output:

[root@d-mpk12-53-238 root]# ipmitool -H 129.146.53.95 -U root -P changeme -I lan

sel list -v
SEL Record ID	: 0100
Record Type	: 00
Timestamp	: 01/10/2002 20:16:16
Generator ID	: 0001
EvM Revision	: 04
Sensor Type	: Critical Interrupt
Sensor Number	: 00
Event Type	: Sensor-specific Discrete
Event Direction	: Assertion Event
Event Data	: 04ff00
Description	: PCI PERR

■FIGURE D-3shows an example of a DMI log screen from BIOS Setup Page, with a parity error.
