this looks like a generic commands for all that does the power cycle?

Yes, Note that it's the platform reboot script, so this is only for Mellanox platforms.

@mykolaf Can you create a separate PR for 201811 branch please? This change cannot be cherry-picked cleanly. Thanks! |

We noticed that null characters sometimes appear in our logs after we started using power cycle to reboot.
This gets in the way of greping the logs.
- What I did
Made sure the filesystem is synced and unmounted before performing the power cycle.
- How I did it
- How to verify it
Perform multiple reboots, then
cat -A /var/log/syslog* | grep -A 15 rebooting | grep ^@
Check that no null characters are present
- Description for the changelog
Made sure the filesystem is synced and unmounted before performing the power cycle on Mellanox platforms.
