Create Cluster?

You can create a cluster from the Create Cluster? menu. You also have the option to delete the node from the cluster if the node that is selected is in a cluster.

The Create Cluster? option allows you to create a new SAN Volume Controller cluster. Press the select button on the Create cluster? menu to start creating a cluster. Figure 1 shows the sequence of the create cluster menu options.

From the front panel, when you create a cluster, you can set either the IPv4 or the IPv6 address for Ethernet port 1. If required, you can add more management IP addresses by using the SAN Volume Controller Console or the CLI.

Delete Cluster?

The Delete Cluster? option deletes the cluster state data from the node. This option is displayed only if you select the Create Cluster? option on a SAN Volume Controller node that is already a member of a cluster.

Use this option as the final step in decommissioning a cluster after the other nodes have been removed from the cluster using the command-line interface (CLI) or the graphical user interface (GUI).

Attention: Use the front panel to remove cluster state data from a single node cluster. To remove a node from a multi-node cluster, always use the CLI or the remove node options from the GUI.
From the Delete Cluster? panel, perform the following steps to delete the cluster state data from the node:
  1. Press and hold the up button.
  2. Press and release the select button.
  3. Release the up button.
After the option is run, the node shows "Cluster:" with no cluster name. If this option is performed on a node that is still a member of a cluster, the cluster will show error 1195, "Node missing," and the node will still appear in the list of nodes in the cluster. The node should be removed by using the GUI or CLI.

Use the up button to return to the Create Cluster? option.
