[GAB parameter] Control port seed [Description and command] 
This option defines the minimum number of nodes that can form the cluster. This option controls the forming of the cluster. If the number of nodes in the cluster is less than the number specified in the gabtab file, then the cluster will not form. For example: if you type gabconfig -c -n4, then the cluster will not form until all four nodes join the cluster. If this option is enabled using the gabconfig -x command then the node will join the cluster even if the other nodes in the cluster are not yet part of the membership. Use the following command to set the number of nodes that can form the cluster: gabconfig -n count Use the following command to enable control port seed. Node can form the cluster without waiting for other nodes for membership: gabconfig -x
