svcs
* svcs -a: Lists all services currently installed, including their state.
* svcs -d FMRI: Lists dependencies for FMRI.
* svcs -D FMRI: Lists dependents for FMRI.
* svcs -l FMRI: Provides a long listing of information about FMRI; includes dependency information
* svcs -p FMRI: Shows relationships between services and processes.
* svcs -t: This change is temporary (does not persist past a boot).
* svcs -x: Lists erred services and explains why a service is not available.
* svcs -xv: Verbose debugging information.
svcadm
* svcadm clear FMRI: Clear faults for FMRI.
* svcadm disable FMRI: Disable FMRI.
* svcadm enable FMRI: Enable FMRI.
* svcadm refresh FMRI: Force FMRI to read config file.
* svcadm restart FMRI: Restart FMRI.
