I suspect that it's "svcadm restart A". Does that do the > right thing? I think this is true if: - a restart method is defined for service A AND - the "restart_on" value expressed in the dependency relationship of B on A is of type "restart" or "refresh". man smf(5) for this mess. > If so, why? Because the dependency attribute of B on A says to restart B if A is stopped due to error, non-error (admin restart) or refresh. > My guess is that it > > 1) stops B because it depends on A > 2) stops A (because you asked for a restart of A) > 3) starts A (because you asked for a restart of A) > 4) starts B (because it's enabled and its dependencies are running) CT
