Group Membership and Atomic Broadcast configuration files
The following files are required by the VCS communication services for Group
Membership and Atomic Broadcast (GAB).
/etc/gabtab
After installation, the file /etc/gabtab contains a gabconfig(1M) command
that configures the GAB driver for use.
The file /etc/gabtab contains a line that resembles:
/sbin/gabconfig -c -n N
where the -c option configures the driver for use and -n N specifies that the
cluster will not be formed until at least N systems are ready to form the cluster.
N is the number of systems in the cluster.
