After you install VCS, 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:
where the -c option configures the driver for use and -nN specifies that the cluster is not formed until at least N nodes are ready to form the cluster. By default, N is the number of nodes in the cluster.
Note
The use of the -c -x option for /sbin/gabconfig is not recommended. The Gigabit Ethernet controller does not support the use of -c -x.
