Just simple add the code from OnPlayerSpawn to the command, like so;

pawn Код:

CMD:dm(playerid, params[]) {
        new randomcoords = random(sizeof(DMSpawn));
        SetPlayerPos(playerid, DMSpawn[randomcoords][0], DMSpawn[randomcoords][1], DMSpawn[randomcoords][2]);
            return 1;
}

I'm sure you can add the messages & checks to the command yourself.
