If you mean stonith resource - for all I know location it does not
affect stonith operations and only changes where monitoring action is
performed. You can create two stonith resources and declare that each
can fence only single node, but that is not location constraint, it is
resource configuration. Showing your configuration would be helpflul to

In two-node cluster you can set pcmk_delay_max so that both nodes do not
attempt fencing simultaneously.

Not that I'm aware of.
