Description John Westlund 2017-03-28 15:20:22 MDT 
I have a customer that is trying to change memory modes on KNL hardware that appears to not support changing memory modes via reboot -- the memory mode can only be changed via a power cycle.

All documentation I see references running reboot on the compute node as part of the KNL Slurm configuration. I'm asking them to try running an ipmi power chassis reset locally on the client as the reboot command -- I'm not sure if that will work.

Is there a method of issuing a power control command on the system hosting the slurmctld when the user requests to change memory modes?

Thanks

Downgrading the severity here - please see https://www.schedmd.com/support.php for details on severity levels.

Unfortunately I need to hand you off to Jacob for a bit, as I don't believe we have any support contracts in place at present; until he gives me the go ahead I can't directly engage on questions.

Thanks Tim. I'll share the severity level definitions with the people on this end requesting it be Sev1

Once a support contract is in place for this system then the Slurm support team can engage.
