The boot sequence has changed for Solaris Local Zones related Service Management Facility (SMF) services in Solaris 11.4.
See related article:
To ensure the Solaris Local Zones do not start before the required Veritas SMF services have all been started, Veritas recommends setting the "autoboot" zonecfg attribute to "false".
Steps:
1.] Run the zonecfg command against the Solaris Local Zone to be updated
Sample syntax
# zonecfg -z ldom06_zone15
At the zonecfg prompt, type the following syntax to disable autoboot (autostarting) of the Solaris Local Zone:
zonecfg:ldom06_zone15> set autoboot=false
2.] The autoboot attribute will not be displayed when set to "false" with the zonecfg "info" argument
zonecfg:ldom06_zone15> info
zonename: ldom06_zone15
zonepath: /export/zones/ldom06_zone15

3.] Verify & commit the zonecfg configuration changes and exit.
zonecfg:ldom06_zone15> verify
zonecfg:ldom06_zone15> commit
zonecfg:ldom06_zone15> exit
NOTE: The Solaris Local Zone will no longer start (boot) automatically when the server restarts.
The "zoneadm -z boot" syntax will still enable the user to start the Solaris Local Zone, however, requires manual intervention or automation via the Veritas Cluster Server (VCS) Zone Agent.

Veritas had to make a change to the SMF "/var/svc/manifest/system/vxodm/odm.xml" manifest file, ensuring Veritas vxodm (VERITAS Oracle Disk Manager) doesn't go into maintenance mode..
