<p class="MsoNormal"><span style="color:#1F497D">I conducted two tests. For case 1, the system can recover. For case 2, it can’t.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Case 1: pull the active controller management cable for longer than 30s, and then reinsert it<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Case 2: pull the active controller management cable for less than 30s, and then reinsert it<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">For case 2, since controller-1 was shown as “offline” on controller-0. “collect all” can’t get the information of controller-1. So I copied the whole folder “/var/log” of controller-1. It is included in the shared
zip package. If you need more information, let me know. Thanks for your help again!<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">I am working on the <a href="https://bugs.launchpad.net/starlingx/+bug/1815513">
LP 1815513</a>. Based on my tests, if I unplug the cable of active controller for management network for a long time (for example, 30s), and then plug it, the whole system can recover after some reboots. But if I unplug the cable for a short time, and then
plug it. The whole system can’t recover. I need to lock/unlock controllers manually to bring the system back. So my questions are:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">1. Is the behavior acceptable? (recover the system by manual lock/unlock operations)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">2. If the answer is no for #1, we need the system to recover automatically. I am not familiar with internal maintenance logics, could you give me some hints?<o:p></o:p></span></p>
