just like Angelos described, we also have logic in our poweroff script that checks if the node is really IDLE and only sends the poweroff command if that's the case.
hosts=$(scontrol show hostnames $1)
for host in $hosts; do
scontrol show node $host | tr ' ' '\n' | grep -q 'State=IDLE+POWER$'
if [[ $? == 1 ]]; then
echo "node $host NOT IDLE" >>$OUTFILE
echo "node $host IDLE" >>$OUTFILE
ssh $host poweroff

Subject: [External] [slurm-users] [slurm 20.02.3] don't suspend nodes in down state
how can I prevent slurm, to suspend nodes, which I have set to down state for maintenance?
I know about "SuspendExcNodes", but this doesn't seem the right way, to roll out the slurm.conf every time this changes.
Is there a state that I can set so that the nodes doesn't get suspended?
It happened a few times that I was doing some stuff on a server and after our idle time (1h) slurm decided to suspend the node.
