Actions for a service are 54 carried out by its assigned service restarter agent. The default service 55 restarter is \fBsvc.startd\fR (see \fBsvc.startd\fR(1M)). 56 .SH OPTIONS 57 The following options are supported: 58 .sp 59 .ne 2 60 .na 61 \fB-S\fR \fIstate\fR 62 .ad 63 .RS 20n 64 For the subcommands which normally operate on explicit \fIFMRI\fRs or an 65 \fIFMRI\fR pattern, the \fB-S\fR option can be used to select all \fIFMRI\fRs 66 in the given state. 67 .RE 68 69 .sp 70 .ne 2 71 .na 72 \fB\fB-v\fR\fR 73 .ad 74 .RS 20n 75 Print actions verbosely to standard output. 76 .RE 77 78 .sp 79 .ne 2 80 .na 81 \fB-Z\fR 82 .ad 83 .RS 20n 84 Administer services in all zones.

If an abbreviated \fIFMRI\fR (a fault 107 management resource identifier) matches more than one service or instance, a 108 warning message is displayed and that operand is ignored. 109 If a pattern matches more than one service or instance, the subcommand is 110 applied to all matches. See \fBsmf\fR(5). 111 .sp 112 .LP 113 In the case that the service has more than one instance, \fBsvcadm\fR return a 114 non-zero exit status. 115 .sp 116 .ne 2 117 .na 118 \fB\fBenable\fR \fB[\fR\fB-rst\fR\fB]\fR {\fIFMRI\fR | \fIpattern\fR}...\fR 119 .ad 120 .sp .6 121 .RS 4n 122 Enables the service instances specified by the operands. For each service 123 instance, the assigned restarter will try to bring it to the online state. This 124 action requires permission to modify the "general" property group of the 125 service instance (see \fBsmf_security\fR(5)). 126 .sp 127 If the \fB-r\fR option is specified, \fBsvcadm\fR enables each service instance 128 and recursively enables its dependencies. 129 .sp 130 If the \fB-s\fR option is specified, \fBsvcadm\fR enables each service instance 131 and then waits for each service instance to enter the \fBonline\fR or 132 \fBdegraded\fR state. \fBsvcadm\fR will return early if it determines that the 133 service cannot reach these states without administrator intervention. 134 .sp 135 If the \fB-t\fR option is specified, \fBsvcadm\fR temporarily enables each 136 service instance. Temporary enable only lasts until reboot. This action 137 requires permission to modify the "restarter_actions" property group of the 138 service instance (see \fBsmf_security\fR(5)).

For each service 150 instance, the assigned restarter will try to bring it to the disabled state. 151 This action requires permission to modify the "general" property group of the 152 service instance (see \fBsmf_security\fR(5)). 153 .sp 154 If the \fB-s\fR option is specified, \fBsvcadm\fR disables each service 155 instance and then waits for each service instance to enter the disabled state. 156 \fBsvcadm\fR will return early if it determines that the service cannot reach 157 this state without administrator intervention. 158 .sp 159 If the \fB-t\fR option is specified, \fBsvcadm\fR temporarily disables each 160 service instance. Temporary disable only lasts until reboot. This action 161 requires permission to modify the "restarter_actions" property group of the 162 service instance (see \fBsmf_security\fR(5)). By default, \fBdisable\fR is 163 persistent across reboot. 164 .sp 165 If the \fB-c\fR option is specified, the given free-form comment is recorded 166 in the (temporary) service configuration under the \fBgeneral/comment\fR 167 property.

See the restarter and service documentation for 202 more information. 203 .sp 204 If the service is managed by \fBsvc.startd\fR(1M), the \fBrefresh\fR method 205 will be invoked if it exists to request the service reread its own 206 configuration. For other restarters, see the restarter documentation. 207 .sp 208 This action requires permission to modify the "restarter_actions" property 209 group of the service instance (see \fBsmf_security\fR(5)). 210 .RE 211 212 .sp 213 .ne 2 214 .na 215 \fB\fBclear\fR {\fIFMRI\fR | \fIpattern\fR}...\fR 216 .ad 217 .sp .6 218 .RS 4n 219 For each service instance specified by the operands, if the instance is in the 220 \fBmaintenance\fR state, signal to the assigned restarter that the service has 221 been repaired.

Additionally, it makes the specified milestone the default 294 boot milestone, which persists across reboot. The default milestone is defined 295 by the \fBoptions/milestone\fR property on the master restarter, 296 \fBsvc:/system/svc/restarter:default\fR.
