Yes it did workout with "system power on" through SP mode.
I have 3210 so its both controllers are in same chassis, therefore power off/on was not an option.
There was some fans noise that suddenly started and it was something related to battery and nvmem, a simple reboot did not slow down fans but reboot -s did work for normalizing fans on this controller. There will be a patch for it but scheduling it ma take time so i tried reboot -s.
