Configuring GAB manually

VCS uses the Group Membership Services/Atomic Broadcast (GAB) protocol for cluster membership and reliable cluster communications. GAB has two major functions.

It handles the following tasks:

  • Cluster membership

  • Cluster communications

To configure GAB

  1. Set up an /etc/gabtab configuration file on each node in the cluster using vi or another editor. The following example shows an /etc/gabtab file:
        /sbin/gabconfig -c -nN

    Where the -c option configures the driver for use. The -nN option specifies that the cluster is not formed until at least N systems are ready to form the cluster. Veritas recommends that you set N to be the total number of systems in the cluster.

    Warning:

    Veritas does not recommend the use of the -c -x option or -x option for /sbin/gabconfig. Using -c -x or -x can lead to a split-brain condition.

  2. Edit the following file on each node in the cluster to change the values of the GAB_START and the GAB_STOP environment variables to 1:

    /etc/default/gab
