on cp1085, IPMI does not work (noticed because sometimes the puppet run gets stuck at the "Loading facts" step?)
i tried the commands from https://wikitech.wikimedia.org/wiki/Management_Interfaces
and locally it fails with:
ipmi_cmd_get_chassis_status: driver timeout
and from remote it fails with:
Error: Unable to establish IPMI v2 / RMCP+ session
Trying to SSH to the mgmt interface failed with:
No more sessions are available for this type of connection!
In Icinga there is an existing comment that this is "known" but there was no ticket yet.
