Last Modified: Apr 28, 2025

Affected Product(s):

Known Affected Versions:
F5OS-C 1.1.0, F5OS-C 1.1.1, F5OS-C 1.1.2, F5OS-C 1.1.3, F5OS-C 1.1.4

Opened: Jan 28, 2020

Severity: 4-Minor

Symptoms

System messages report that BIG-IP system will reboot after the firmware update but the system does not actually reboot. Note: If you try to reboot while the update is in progress, the reboot fails and logs a message indicating that the system is going down for reboot. It does not reboot, however. Messages displayed: -- Failed to start reboot.target: Transaction contains conflicting jobs 'stop' and 'start' for systemd-reboot.service. Probably contradicting requirement dependencies configured. -- See system logs and 'systemctl status reboot.target' for details. -- Broadcast message from root@localhost on ttyS0 (Tue 2021-01-28 10:18:33 PST): The system is going down for reboot NOW!

Impact

The system prevents rebooting while the firmware upgrade is in progress, but the system reports an erroneous message indicating that a reboot will occur.

Conditions

-- Firmware is being updated. -- You initiate a system reboot.

Workaround

Do not attempt to reboot during a firmware update. The message is erroneous and you can safely ignore it.
