This section explains the procedure on how to change the state to DOWN of the node during recovery from LEFTCLUSTER state.
If a node is shut down normally, it is considered DOWN by the remaining nodes. If it leaves the cluster unexpectedly, it will be considered LEFTCLUSTER. It is important to mark a node DOWN as SOON as possible to allow normal cluster operation for the remaining nodes. The menu option [Tools] - [Mark Node Down] allows nodes to be marked as DOWN.
Note
Marking a node DOWN should be only done if the node is actually down (inoperable or inoperative); otherwise, this could cause data corruption.
To do this, select [Tools] - [Mark Node Down]. This displays a dialog of all of the nodes that consider another node to be LEFTCLUSTER. Clicking on one of them displays a list of all the nodes that node considered LEFTCLUSTER. Select one and then click [OK]. This clears the LEFTCLUSTER status on that node.
Refer to "Chapter 5 LEFTCLUSTER state" for more information on the LEFTCLUSTER state.
