There is also series of guides for cluster maintenance under deployment guides, which may be helpful for you. <a href="https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-10/Cisco-Expressway-Cluster-Creation-and-Maintenance-Deployment-Guide-X8-10.pdf">https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-10/Cisco-Expressway-Cluster-Creation-and-Maintenance-Deployment-Guide-X8-10.pdf</a></div><div class="gmail_default" style="font-family:"trebuchet ms",sans-serif"><br></div><div class="gmail_default" style="font-family:"trebuchet ms",sans-serif">Aside from upgrades, the few times I've had to do something like this was restarting Expressways to clear software errors. I did the primary, then secondary nodes once the primary was back online. This is also the order suggested for upgrades. I personally do not see any value in doing one cluster before the other, but most of the deployments I see are the simple and supported ones. </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Sep 21, 2017 at 3:32 PM, Lelio Fulgenzi <span dir="ltr"><<a href="mailto:lelio@uoguelph.ca" target="_blank">lelio@uoguelph.ca</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
Just wondering what people are doing when they need to restart their expressway cluster? Since C is the one initiating the connection to E, and because the primary is reaching out to subscribers, I'm thinking:<br>
<br>
Shutdown Order<br>
<br>
C primary<br>
C subscribers<br>
E primary<br>
E subscribers<br>
<br>
(Re)Start Up Order<br>
<br>
E subscribers<br>
E primary<br>
C subscribers<br>
C primary<br>
<br>
Thoughts?<br>
