During boot, the BIOS may briefly display a red warning message indicating that the System Event Log (SEL) is full. This message appears after multiple reboots, due to the limited SEL storage space of the On-Board Platform Instrumentation. The SEL storage space of the mBMC allows for the storage of 92 SEL entries. A typical reboot adds several informational event messages to the SEL as part of the normal boot process.
The warning message displayed by the BIOS is not an error. It is a warning message that the SEL is full and that no more system event messages can be logged until the SEL is cleared.
The System Event Log (SEL) of the On-Board Platform Instrumentation should be cleared regularly. There are several methods of clearing the SEL, including:
- going to BIOS Setup (F2) and clearing the SEL
- using the SEL Viewer (included on the Intel® Server Deployment Toolkit and the Software Update Package and available as a download)
- via Intel® Server Management 8.x software
Alternatively, some Intel servers (Intel® Server Board SE7520AF2, Intel® Server Board SE7520BD2 and Intel® Server Board SE7520JR2) have a connector to allow upgrade to the Intel Management Module (IMM) Professional or Advanced editions. The Intel Management Modules include an increased SEL capacity up to 3,276 SEL entries.
