Table 2. SMF Service States
State Description
uninitialized This is the initial state of all services until its restarter (usually svc.startd) moves services to another state.
offline The instance is enabled but not yet running or unable to run.
online The instance is enabled and running.
maintenance The instance is enabled but unable to run for some reason, and administrative action will be required.
disabled The instance is disabled.
legacy-run The service is not directly managed by SMF, but it was started at some point.
If, for any reason, we wanted to restart a service, we could use the svcadm restart command.
