The LEFTCLUSTER state may occur because a particular node (called the offending node) has been rebooted improperly. If a node is rebooted using the normal reboot commands like init(1M) or shutdown(1M), the LEFTCLUSTER state should not occur.
The LEFTCLUSTER state will occur if you reboot the offending node with commands like uadmin(1M) or reboot(1M). In this case the procedure to clear the LEFTCLUSTER state is as follows:
Make sure the offending node is rebooted in multi-user mode.
Use Cluster Admin to log on to one of the surviving nodes in the cluster. Invoke the CF GUI by selecting [Mark Node Down] from the [Tools] pull-down menu. Mark the offending node as DOWN.
The offending node will rejoin the cluster automatically.
