If it is in takeover mode then issue `cf giveback` from controller A CLI and it'll power up. </P><P>If it's halted you'll need to make a console connection (if you haven't configured the BMC) and you should see the loader prompt. Type `bye` at the loader prompt and the controller should boot unless there are any issues, in which case you'll need to halt boot with ctrl/c when prompted for Special Boot Menu and select option 5, Maintenance Mode Boot.</P></BODY></HTML> Tue, 09 Aug 2011 05:17:09 GMT andrc 2011-08-09T05:17:09Z Netapp 2020, controller b software start? https://community.netapp.com/t5/ONTAP-Hardware/Netapp-2020-controller-b-software-start/m-p/78462#M5547 <HTML><HEAD></HEAD><BODY><P>Controller A is up and functioning.&nbsp; Controller b was halted.&nbsp; Is there a way to start controller b via commands while a is active?</P></BODY></HTML> Thu, 05 Jun 2025 06:48:31 GMT https://community.netapp.com/t5/ONTAP-Hardware/Netapp-2020-controller-b-software-start/m-p/78462#M5547 mattbettis 2025-06-05T06:48:31Z Netapp 2020, controller b software start? https://community.netapp.com/t5/ONTAP-Hardware/Netapp-2020-controller-b-software-start/m-p/78467#M5548 <HTML><HEAD></HEAD><BODY><P>That depends on if controller B is halted or in takeover mode, you can check this with `cf status` on controller A CLI.
