Hi Danishka: Yes. I think this is related to Heartbeat. If Heartbeat miss count reaches threshold, node will graceful recovery , which reboot the node. BR Austin Sun.

A couple of times we noticed all nodes except the active controller rebooted after reboot of the switch. When we purposely reboot the switch, only one storage node rebooted. I understand the importance of the redundant switch, but is this possible with starlingX? (Maybe an issue related to heartbeats). Regards, Danishka
