After a BIOS upgrade on SSLv, which reboots the hardware, you receive the following notification even though the hardware was rebooted during the upgrade:
BIOS Version: 0ACNU026
ME Version: 0A:4.1.5.2
BMC Version: 3.30.32501
Power CPLD Version: 2.3
HDD1 CPLD Version: 20190221
HDD2 CPLD Version: 20190221
Bridge CPLD Version: 20190221
Bypass CPLD Version: D.07
SAS IOC Version: 10.00.01.00
[WARNING] A cold power cycle is required to enable the latest firmware to reset and cleanly load the updated firmware version.
A BIOS update often requires an additional restart because the update process needs to fully apply the new settings to the system firmware, which typically happens during the boot sequence after the initial restart, essentially "finalizing" the changes made to the BIOS.
Follow the steps noted to reboot one additional time after the initial BIOS upgrade reboot.
