pmadm is the administrative command for the lower level of the SAF hierarchy, that is, for service administration. See the pmadm(1M) man page. A port can have only one service associated with it, although the same service might be available through more than one port. pmadm performs the following functions:
Prints service status information from the port monitor's administrative file
Adds or removes a service
Enables or disables a service
Installs or replaces a per-service configuration script
In order to identify an instance of a service uniquely, the pmadm command must identify both the service (-s) and the port monitor or port monitors through which the service is available (-p or -t).
