/etc/rc.config.d/
gabconf
After you install SFCFS, the file /etc/gabtab contains a gabconfig(1)
command that configures the GAB driver for use.
The file /etc/gabtab contains a line that resembles:
/sbin/gabconfig -c -nN
The -c option configures the driver for use. The -nN specifies that
the cluster is not formed until at least N nodes are ready to form the
cluster. Symantec recommends that you set N to be the total number
of nodes in the cluster.
Note: Symantec does not recommend the use of the -c -x option for
/sbin/gabconfig. Using -c -x can lead to a split-brain condition.
