Title: Antminer S9 Hard Reboot
Post by: agswin on October 09, 2018, 04:05:03 AM
Hello and thanks ahead of time. Is there a way to hard reboot (power cycle or equivalent) an antminer s9 remotely? The reboot in the gui doesnt seem to fix alot of issues that a hard reboot (unplug/replug) solves. I can use putty to access the miner. Just wondering if there are linux commands to shutdown and restart that is equivalent to a hard reboot.

The only way to perform a hard reboot is to remove the power and re apply it, unless you have a smart PDU or someone to unplug it / disconnect the power I don't think you'll be able to do what you want.

GUI reboot is soft reboot. Also the API reboot call is a soft reboot.

If you use putty you can access the shell and then run /sbin/reboot which seems equivalent to a hard reboot.

I have found you really need to power cycle the unit to reinitialize cards that are having issues. You can buy a device that allows you to SSH in and physically switch power on and off

You want something like this:

https://www.amazon.com/D-Link-Energy-Monitoring-Amazon-DSP-W215/dp/B00K4YEI28/

Obviously you need to make sure it supports your PSU (110v versus 220v) and the proper amperage.

The link I posted was for informational use only, it is not a specific recommendation.

You can try this method from here  On-board auto reboot with Antminer S9 (daily reboots)  (https://bitcointalk.org/index.php?topic=4720967.0) At least you can do the hard reboot automatically and schedule what time you want to reboot it.

For now, I don't find any methods that you can fully reboot remotely your miner, the above link maybe solved your issue.

I just tried /sbin/reboot and it restarted a board that would not restart using the gui reboot. Thanks guys

Glad I could help! I haven't yet found any difference between /sbin/reboot and physically power cycling the miner.
