A soft reboot should allow the server to shut down gracefully. A reset wouldn't do that, at least as I understand it. A reset would be more appropriate for a hard reboot, although I see Dmitry had a couple of other concerns with implementing it as a reset on the review.

Hi,

Is there a reason for powering off and on[1] instead of resetting server during SOFT_REBOOT?

I have a patchset[2] that resets the server instead of power cycling it.

[1] https://github.com/openstack/ironic/blob/master/ironic/drivers/modules/ipmitool.py#L820

   elif power_state == states.SOFT_REBOOT:

             _soft_power_off(task, driver_info, timeout=timeout)

             driver_utils.ensure_next_boot_device(task, driver_info)

             _power_on(task, driver_info, timeout=timeout)
