NAME
svcadm - manipulate service instances SYNOPSIS
/usr/sbin/svcadm [-v] enable [-rst] {FMRI | pattern}... /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.

The invocation and non-interactive output are Evolving. svcprop(1), svcs(1), inetd(1M), init(1M), svccfg(1M), svc.startd(1M), libscf(3LIB), contract(4), attributes(5), smf(5), smf_security(5) 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. 27 July 2005 svcadm(1M)
