+==== Power Outage ====
+Cables are all on UPS for both controllers and storage yet this happened ...
+<code>
+New alerts:
+* Backup Controller (A) - hpcm40eth0c1.wesleyan.edu had an unscheduled system reboot. The operating
+system successfully came back online at Fri Dec 19 11:07:24 2025.
+</code>
+What's weirder is that both M40 controllers have the almost identical uptime but I only got an email about controller A reboot and B is now active ... maybe that is normal, but my other TrueNAS appliance, the X20, plugged into same UPS pdus remained up and uptime is 135 days.
+**Next prolonged outage look at power leds !!!**
+==== middlewared ====
+As the next step, we would recommend restarting the middleware service on the active controller to refresh the UI/reporting communication state.
+This can be performed through SSH using:
+service middlewared restart
+Please note that restarting middleware will temporarily interrupt access to the TrueNAS web interface while the service restarts. Replication tasks and middleware-managed services may also briefly interrupt during this process, however they should resume automatically once middleware finishes restarting. The controller itself will not reboot and storage services should remain online.
