The boot-archive service is controlled by SMF. The service instance is svc:/system/boot-archive:default.
To check the status of the boot-archive service, type this command:
$ svcs boot-archive STATE STIME FMRI online 10:35:14 svc:/system/boot-archive:default
The service must always be enabled. Otherwise, automatic recovery of the boot archive upon a system reboot might not occur. As a result, the boot archive could become unsynchronized or corrupted and would prevent the system from booting.
To enable a disabled boot-archive service, type the following:
$ svcadm enable system/boot-archive
