Cluster: Delete a Cluster Node and Dealing with Problems

You can delete nodes in a cluster. Proceed as follows:

1. Log in to your Software Appliance and open the Cluster page.

2. In the section Cluster Members, click Unlock to make changes.

3. In the Cluster Members list, find the node you want to delete and click Remove.

4. In the Remove dialog, activate the confirmation Yes, I want to remove this node and click Remove.
   

   

The node will be removed from the cluster. Data on the node will remain untouched by this action.

Dealing with Problems

If the cluster is in a state that makes starting without manual intervention impossible like:

• node keeps showing Connecting

• more than one node shows the Force into Primary function in the Action column active

the Force into Primary option has to be used.

1. In the Cluster page, go to the section Cluster Members and click Unlock to make changes.

2. Find the node with the highest LTID and click Force into Primary which appears for this node only.

3. You are prompted to confirm the action. For security reasons and because the data of the other nodes will be destroyed, you have to explicitly type the confirmation: DESTROY ALL DATA.
   

   

4. Click Force into Primary to initiate the following:

   1. In the event that the the Connectivity status of a node is showing Disconnected, the node will be removed from the cluster configuration.

   2. If the Connectivity status of a node shows Connecting, the node will be reconnected to the cluster configuration.

   3. Data on all other connected nodes will be deleted.

   4. Data from the current node will be transferred to all other connected nodes.
