Bug ID 627961: nic_failsafe reboot doesn't trigger if HSB fails to disable interface

Last Modified: Apr 28, 2025

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
12.1.1, 12.1.1 HF1, 12.1.1 HF2, 12.1.2

Fixed In:
12.1.2 HF1

Opened: Nov 10, 2016

Severity: 3-Major

The HSB driver attempts a nic_failsafe in the case of failing to disable the interface.

TMM may restart continuously resulting in interfaces bouncing constantly.

The driver disables nic_failsafe prior to triggering the nic_failsafe. This is in hsb_ifdown_go_dead.

Reboot the device.

This release fixes issues where nic_failsafe reboot did not happen on HSB failures.
