If you have a pending BIOS upgrade, a routine reset takes longer than expected, and causes the 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 Integrated Lights Out Manager (ILOM).
You select the Oracle ILOM 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.
Caution - Data corruption and system downtime. Interrupting the firmware upgrade process can corrupt the firmware and render the server inoperable. Do not interrupt the upgrade. Allow the process to finish.
