Power_provisioning server attribute

I got an error when I tried to enable server power_provisioning by a qmgr commond,

Qmgr: set server power_provisioning=true
qmgr obj= svr=default: Cannot set attribute, read only or insufficient permission power_provisioning
qmgr: Error (15003) returned from server

I can set a vnode’s power_provisioning to true without any error. I found this attribute by reading man page and Administrator’s Guide. So I am wondering if I can use this feature to power on/off compute nodes automatically.

Am I misunderstanding this attribute, or I am just setting it incorrectly?

Please try this :
qmgr -c ‘s pbshook PBS_power enabled=true’

and then check qstat -Bf | grep -i power

Great! I got it.
power_provisioning is True now.
Thank you very much for your help.
