I am trying to make a change in my system per use docs. I am trying to do this and keep getting an error. It was already created. I can't find a way to edit this.

crm(live)configure# primitive stonith_sbd stonith:external/sbd pcmk_delay_max="30"
ERROR: syntax in primitive: Unknown arguments: pcmk_delay_max=30 near <pcmk_delay_max=30> parsing 'primitive stonith_sbd stonith:external/sbd pcmk_delay_max=30'

Any help appreciated.
Thank you
