The following are issues you might encounter when booting a system:
Services do not start at boot time.
A system might hang during boot time, if there are problems starting any Service Management Facility (SMF) services. To troubleshoot this type of issue, you can boot the system without starting any services. For more information, see How to Investigate Problems Starting Services at System Boot in Managing System Services in Oracle Solaris 11.2
system/filesystem/local:default SMF service fails during boot.
Local file systems that are not required to boot the system are mounted by the svc:/system/filesystem/local:default service. When any of those file systems cannot be mounted, the service enters a maintenance state. System startup continues, and any services that do not depend on filesystem/local are started. Subsequently, any services that require filesystem/local to be online before starting through dependencies are not started. The workaround for this issue is to change the configuration of your system so that a sulogin prompt is displayed immediately after the service fails instead of allowing the system startup to continue.
