1.How
to list the configured services from SMF ?
#

This
output will give list of legacy services,online services,disabled services and
offline services.

3.How to see complete service information and log file name ?
bash-3.00#
svcs -l svc:/system/zones:default
fmri svc:/system/zones:default

enabled true
state online

logfile /var/svc/log/system-zones:default.log
restarter svc:/system/svc/restarter:default
dependency require_all/none
svc:/milestone/multi-user-server (online)
4.To see how many services depends on particular service
?(Ex:svc:/system/zones:default)
bash-3.00#
svcs -D svc:/system/zones:default
STATE STIME FMRI
Here
none of the system services are depends on zones services.
5.To see what are the services required to start particular service ?
bash-3.00#
svcs -d svc:/system/zones:default
STATE STIME FMRI
online May_17 svc:/milestone/multi-user-server:default
i.e "Zones" service depends on
"multi-user-server" service.
6.How
do you see service dependency map ?
bash-3.00#
svcs -p svc:/application/graphical-login/cde-login:default
STATE STIME FMRI
online May_17
svc:/application/graphical-login/cde-login:default
May_17 3429 dtlogin

May_17 3733 Xorg
May_17 4070 dtlogin
May_17 4145 dtgreet
7.How
to check SMF services status using one command ?
The
below command will report if there is an issue with SMF services.
bash-3.00#
svcs -xv
svc:/application/print/server:default
(LP print server)
State: disabled since Fri May 17 20:07:30 2013
Reason:
Disabled by an administrator.
See: http://sun.com/msg/SMF-8000-05
See: man -M /usr/share/man -s 1M lpsched
Impact:
2 dependent services are not running:
svc:/application/print/rfc1179:default
svc:/application/print/ipp-listener:default
# svcs -a
This output will give list of legacy services,online services,disabled services and offline services.

Service
Management facility administration:In the last post we have seen how to list
the services using SMF commands and here we will see how to administrate those
FMRI(Service) using SMF commands.In Solaris Operating system administration,
You should have fair enough knowledge to start,stop,restart the
SMF service.And also you should know how to troubleshoot if the
service is not coming to online.In the end of the post we will see how to
backup and restore the SMF repository. svcadm is a command which will
be used to administrate the SMF services.
Note:Solaris
10 still supports legacy method of stopping and starting service using rc
scripts.
From man page of svcadm,
bash-3.00#
svcadm
Usage:
svcadm [-v] [cmd [args ... ]]
svcadm enable [-rst] ...
- enable and online service(s)
svcadm disable [-st] ...
- disable and offline service(s)
svcadm restart ...
- restart specified service(s)
svcadm refresh ...
- re-read service
configuration
svcadm mark [-It] ... - set maintenance state
svcadm clear ... - clear maintenance state
svcadm milestone [-d] - advance to a service milestone
Services can be specified using an
FMRI, abbreviation, or fnmatch(5)
pattern, as shown in these examples for
svc:/network/smtp:sendmail
svcadm
svc:/network/smtp:sendmail
svcadm
network/smtp:sendmail
svcadm

1. How To enable the SMF service ?
First
you list the service which you want to enable using svcs command.Then you can
use svcadm to enable the service and you can monitor the service status using
svcs command.
Sometimes you
need to use complete FMRI(svc:/network/ipfilter:default)
bash-3.00#
svcs ipfilter
STATE STIME FMRI
disabled May_17
svc:/network/ipfilter:default
bash-3.00#
svcadm enable ipfilter

bash-3.00#
svcs ipfilter
STATE STIME FMRI
online 11:44:31 svc:/network/ipfilter:default
2.How
to Disable the SMF service ?
You
can disable the service using svcadm disable command and check the
staus using svcs.
bash-3.00#
svcadm disable
svc:/network/ipfilter:default
bash-3.00#
svcs svc:/network/ipfilter:default
STATE STIME FMRI
disabled 11:50:00 svc:/network/ipfilter:default
3.How to Enable/Disable service temporarily ?
In
SMF ,we have an option to enable/disable the service temporarily.This
disable will not persist across the reboot.You see that temporary flag in the enabled
status.
bash-3.00#
svcadm disable -t svc:/network/ipfilter:default
