HP iLO 4 Firmware Issues

32434wqreRecently there has been an issue raised with HP that in rare  instances,  on a ProLiant Gen8 series server with HP Integrated Lights-Out 4 (iLO 4) Firmware Versions 1.30, 1.32, 1.40 or 1.50, intermittent Non-Maskable Interrupt (NMI) events may occur. After rebooting the server, the operating system loads properly and no additional impact to system operation will occur.

If this issue occurs, the operating system will indicate that an NMI has happened; however, the specific indication will vary by OS:

  • VMware ESXi operating systems will experience a Purple Screen of Death (PSOD).
  • Linux operating systems will display a message indicating that an NMI occurred.
  • Windows will experience a Blue Screen of Death (BSOD).

Upon investigation the Integrated Management Log (IML) will contain NO information about the NMI event.  This issue has been reported in both virtualized and non-virtualized operating system environments and can occur due to an unexpected PCIe event in the iLO 4 subsystem that may result in an NMI when iLO 4 is gathering system management information.This affects the Integrated Lights-Out 4 (iLO 4) subsystem and is specific to iLO 4 Firmware Versions 1.30, 1.32, 1.40 and 1.50.

HP has created a new firmware version 1.51 (or later) that correctly fixes the issue.  You can get it HERE
