The boot sequence has changed for Solaris Local Zones related Service Management Facility (SMF) services in Solaris 11.4.

Solaris 11.4 introduced changes to the boot sequence for Solaris Zone related services impacting Veritas vxodm startup

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.

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..
