Yes, for SX it's possible so that admins can reconfigure the system. Platform services are kept running. Though I don't know what is the policy re applications (if they should be kept running at unlock... please check) Ovidiu ________________________________ From: Alonso, Juan Carlos [juan.carlos.alonso@intel.com] Sent: Friday, May 17, 2019 12:50 AM To: starlingx-discuss@lists.starlingx.io Subject: [Starlingx-discuss] On Simplex, can the active controller be locked? Hello, In a Simplex configuration, is it possible now to Lock/Unlock the active controller-0 (the only controller)? During our sanity we figured out that controller-0 could be locked. For Duplex and Standard configuration we must swact the active controller first, then perform a lock of such controller. Regards. Juan Carlos Alonso
