       /usr/sbin/svcadm [-v] disable [-st] {FMRI | pattern}...

       /usr/sbin/svcadm [-v] restart {FMRI | pattern}...

       /usr/sbin/svcadm [-v] refresh {FMRI | pattern}...

       /usr/sbin/svcadm [-v] clear {FMRI | pattern}...

       /usr/sbin/svcadm [-v] mark [-It] instance_state {FMRI | pattern}...

       /usr/sbin/svcadm [-v] milestone [-d] milestone_FMRI

       /usr/sbin/svcadm [-v] restarter_FMRI {FMRI | pattern}...

       svcadm  issues  requests  for  actions on services executing within the service management facility (see smf(5)). Actions for a service are
       carried out by its assigned service restarter agent. The default service restarter is svc.startd (see svc.startd(1M)).

OPTIONS

       The following options are supported:

       -v	       Print actions verbosely to standard output.

SUBCOMMANDS

   Common Operations
       The following subcommands are used during the typical administration of a service instance.

       For subcommands taking one or more operands, if the operand specifies a service (instead of a service instance), and that service has  only
       a  single  instance,  svcadm  operates on that instance. If an abbreviated FMRI (a fault management resource identifier) or pattern matches
       more than one service, a warning message is displayed and that operand is ignored.

       In the case that the service has more than one instance, svcadm return a non-zero exit status.

       enable [-rst] {FMRI | pattern}. . .

	   Enables the service instances specified by the operands. For each service instance, the assigned restarter will try to bring it to  the
	   online state. This action requires permission to modify the "general" property group of the service instance (see smf_security(5)).

	   If the -r option is specified, svcadm enables each service instance and recursively enables its dependencies.

	   If  the  -s	option	is specified, svcadm enables each service instance and then waits for each service instance to enter the online or
	   degraded state. svcadm will return early if it determines that the service cannot reach these states  without  administrator  interven-
	   tion.

	   If  the -t option is specified, svcadm temporarily enables each service instance. Temporary enable only lasts until reboot. This action
	   requires permission to modify the "restarter_actions" property group of the service instance (see smf_security(5)). By default,  enable
	   is persistent across reboot.

       disable [-st] {FMRI | pattern}. . .

	   Disables  the service instance specified by the operands. For each service instance, the assigned restarter will try to bring it to the
	   disabled state. This action requires permission to modify the "general" property group of the service instance (see smf_security(5)).

	   If the -s option is specified, svcadm disables each service instance and then waits for each service instance  to  enter  the  disabled
	   state. svcadm will return early if it determines that the service cannot reach this state without administrator intervention.

	   If  the  -t	option	is  specified,	svcadm temporarily disables each service instance. Temporary disable only lasts until reboot. This
	   action requires permission to modify the "restarter_actions" property group of the service instance (see smf_security(5)). By  default,
	   disable is persistent across reboot.

       restart {FMRI | pattern}. . .

	   Requests  that  the	service  instances  specified  by  the	operands  be  restarted.  This	action	requires  permission to modify the
	   "restarter_actions" property group of the service instance (see smf_security(5)).

       refresh {FMRI | pattern}. . .

	   For each service instance specified by the operands, requests that the assigned restarter update the  service's  running  configuration
	   snapshot  with  the	values	from  the  current  configuration.  Some  of these values take effect immediately (for example, dependency
	   changes). Other values do not take effect until the next service restart. See the restarter and service documentation for more informa-
	   tion.

	   If the service is managed by svc.startd(1M), the refresh method will be invoked if it exists to request the service reread its own con-
	   figuration. For other restarters, see the restarter documentation.

	   This action requires permission to modify the "restarter_actions" property group of the service instance (see smf_security(5)).

       clear {FMRI | pattern}. . .

	   For each service instance specified by the operands, if the instance is in the maintenance state, signal to the assigned restarter that
	   the	service  has  been repaired. If the instance is in the degraded state, request that the assigned restarter take the service to the
	   online state. This action requires permission to modify the "restarter_actions" property group of the service instance  (see  smf_secu-
	   rity(5)).

   Exceptional Operations
       The following subcommands are used for service development and temporary administrative manipulation.

       mark [-It] instance_state {FMRI | pattern}. . .

	   If  instance_state is "maintenance", then for each service specified by the operands, svcadm requests that the assigned restarter place
	   the service in the maintenance state. See svc.startd(1M) and inetd(1M) for a  detailed  description	of  the  actions  taken  for  each
	   restarter.

	   If  instance_state  is "degraded", then for services specified by the operands in the online state, svcadm requests that the restarters
	   assigned to the services move them into the degraded state.

	   If the -I option is specified, the request is flagged as immediate.

	   The -t option is only valid for maintenance requests. When this option is specified, the request  is  flagged  as  temporary,  and  its
	   effect will only last until the next reboot.

       milestone [-d] milestone_FMRI

	   If  milestone_FMRI is the keyword "none", all services other than the master restarter, svc:/system/svc/restarter:default, will be tem-
	   porarily disabled.

	   If milestone_FMRI is the keyword "all", temporary enable and disable requests for all services will be nullified.

	   If milestone_FMRI is one of the following:

	   svc:/milestone/single-user:default
	   svc:/milestone/multi-user:default
	   svc:/milestone/multi-user-server:default

	   then temporary enable and disable requests for the indicated service and all services it depends on (directly or  indirectly)  will	be
	   nullified. All other services will be temporarily disabled.

	   Changing  the system's current milestone with the "milestone" subcommand will not change the current run level of the system. To change
	   the system's run level, invoke /sbin/init directly.

	   This action requires permission to modify the "options_ovr" property group of the  svc:/system/svc/restarter:default  service  instance
	   (see smf_security(5)).

	   The	-d  option  immediately changes the milestone to the requested milestone, as above. Additionally, it makes the specified milestone
	   the default boot milestone, which persists across reboot. The default milestone is defined by the  options/milestone  property  on  the
	   master  restarter, svc:/system/svc/restarter:default. If this property is absent, "all" is the default. This action requires permission
	   to modify the "options" property group of the svc:/system/svc/restarter:default service instance (see smf_security(5)).

   Operands
       The following operands are supported:

       FMRI		       An FMRI that specifies one or more instances. FMRIs can be abbreviated by specifying  the  instance  name,  or  the
			       trailing portion of the service name. For example, given the FMRI:

			       svc:/network/smtp:sendmail

			       All the following are valid abbreviations:

			       sendmail
			       :sendmail
			       smtp
			       smtp:sendmail
			       network/smtp

			       While the following are invalid:

			       mail
			       network
			       network/smt

			       If  the	FMRI  specifies a service, then the command applies to all instances of that service. Abbreviated forms of
			       FMRIs are unstable, and should not be used in scripts or other permanent tools.

       pattern		       A pattern that is matched against the FMRIs of service instances according to the  "globbing"  rules  described	by
			       fnmatch(5). If the pattern does not begin with "svc:", then "svc:/" is prepended.

       If an abbreviated FMRI or pattern matches more than one service, a warning message is displayed and that operand is ignored.

       Example 1: Restarting a Service Instance

       The following command restarts the NFS server. The full FMRI for the default service instance is: svc:/network/nfs/server:default

       However, you can abbreviate the full FMRI as follows:

       # svcadm restart nfs/server

       Example 2: Disabling the Standard HTTP Server

       The following command disables the standard HTTP server, using an abbreviated FMRI:

       $ svcadm disable http

       Example 3: Enabling an Instance and Its Dependent Instances

       The following command enables the foo:bar instance, and all instances on which it depends:

       $ svcadm enable -r foo:bar

       Example 4: Synchronously enabling an instance

       The  following command enables the foo:bar instance. The command will not return until the instance comes online or svcadm determines it is
       not possible for the service to come online.

       $ svcadm enable -s foo:bar

       Example 5: Restricting and Restoring the Running Services

       The following command restricts the running services to single user mode:

       # svcadm milestone milestone/single-user

       The following command restores the running services:

       # svcadm milestone all

       The following exit values are returned:

       0	Successful completion.

       1	A fatal error occurred. One or more error messages are displayed on standard error.

       2	Invalid command line options were specified.

       3	svcadm determined that a service instance that it was waiting for could not reach the desired state without  administrator  inter-
		vention due to a problem with the service instance itself.

       4	svcadm	determined  that a service instance that it was waiting for could not reach the desired state without administrator inter-
		vention due to a problem with the service's dependencies.

NOTES

       The amount of time svcadm will spend waiting for services and their dependencies to change state is  implicitly	limited  by  their  method
       timeouts.  For  example,  a service using the default restarter whose start method hangs will be transitioned to the maintenance state when
       its timeout expires. svcadm will then consider it impossible for this service to come online without administrator intervention.

       Attempts to synchronously enable a service which depends (directly or indirectly) on a file may fail with an exit  status  indicating  that
       dependencies are unsatisfied if the caller does not have the privileges necessary to search the directory containing the file. This limita-
       tion may be removed in a future Solaris release.
