Workaround
1. Access the BIOS Setup Utility.
2. Navigate to RC Settings > QPI and change:
MMIOH Size per IOH from 2Gb to 4Gb (the default is 2Gb).
3. Navigate to RC Settings > Chipset > NorthBridge Configuration and change:
PCIE-MMIO-64 Bits Support to Enabled (the default is Disabled).
4. Save your changes and exit the BIOS Setup Utility.
5. Reboot the server.
Reset Takes a Long Time and Causes the Server to Power
Cycle
If you have a pending BIOS upgrade, a routine reset might take longer than expected and might
cause your server to power cycle and reboot several times. This is expected behavior as it is
necessary to power cycle the server to upgrade the BIOS firmware. If the upgrade includes an
FPGA update, it can take more than 30 minutes to complete.
A pending BIOS upgrade exists when both conditions are true:
■
You update the BIOS and service processor firmware using Oracle ILOM.
■
You select the option to Delay BIOS Upgrade.
■
The host is powered on.
If you then reboot the server expecting a routine server reset and instead initiate a (delayed)
BIOS upgrade, wait until the upgrade is finished. Do not interrupt the process, as this can result
in corrupted firmware and server down time.
