[GAB parameter] Halt on rejoin [Description and command] 
Default: Disabled This option allows the user to configure the behavior of the VCS engine or any other user process when one or more nodes rejoin a cluster after a network partition. By default GAB will not PANIC the node running the VCS engine. GAB kills the userland process (the VCS engine or the vxconfigd process). This recycles the user port (port h in case of the VCS engine) and clears up messages with the old generation number programmatically. Restart of the process, if required, must be handled outside of GAB control, e.g., for hashadow process restarts _had. When GAB has kernel clients (such as fencing, VxVM, or VxFS), then the node will always PANIC when it rejoins the cluster after a network partition. The PANIC is mandatory since this is the only way GAB can clear ports and remove old messages. Use the following command to enable system halt on rejoin: gabconfig -j Use the following command to disable system halt on rejoin: gabconfig -J
