Since upgrading to version 11.3 we get regular alerts from our FreeNAS about UPS bing on battery power (exact message see below). We have not had those alerts before the update and we do check out UPS and battery regularly. From what we see this happens when the scheduled self check is running. Though we have not changed the UPS or configuration lately and get the alerts since updating the FreeNAS.
Alert message is:
* UPS ups is on battery power.
UPS Mode: Master
Port or Hostname: 192.168.x.x
Auxiliary Parameters (ups.conf):
Auxiliary Parameters (upsd.conf): ##none##
Shutdown Mode: UPS reaches low battery
Shutdown Timer: 30
Please let us know if we can provide more information from logs or run commands to generate information.
Thanks in advance!
