- What I did
Aligned Mellanox specific platform_reboot script to perform a power cycle instead of calling /sbin/reboot. Also added verbosity to the fw upgrade script call.
Motivation: switches were reported "stuck" after a reboot call, most vendors use "hardware reboot" in their platform_reboot scripts. We now go with the same approach of a more harsh reboot.
WARNING:
do not cherry-pick this to 201811. due to different hw-mgmt version 201811 requires separate PR: #3320
