clusterctl bmc power

Change the power state of nodes

Synopsis

Change the power state of the nodes through their service processors.

status report the current state, changing nothing on power on off cut the power without asking the operating system soft ask the operating system to shut down cycle power off and on again reset reset without asking the operating system

Powering many nodes on at once trips rack breakers, so a power-on is sent in batches with a pause between them; both come from the configuration.

A node running a Slurm job is refused unless the workload manager check is turned off, because powering off a running job loses it.
