Managing the N1 nodes
You can manage N+1 nodes without shutting down the entire N+1 DS-System.
To manage the N+1 nodes:
1. On the N+1 menu, click Status.
2. Click the List tab, and then do the following:
3. To add an N+1 node, click Add Node, and then do the following:
a) In the IP/DNS box, type the IP address or DNS name of the node you want to add.
b) In the Port box, enter the port number the node will use for communicating with other nodes of the N+1 configuration.
NOTE: Do not change the port number unless you have a specific requirement to do so.
c) Click OK. The new node is displayed at the bottom of the list. Make a note of the node ID.
IMPORTANT: You must install the DS-System software on the new node and point to the same database and online storage used by the N+1 DS-System. Do not start the DS-System service.
4. To manually update the status of the N+1 nodes in the list, click Refresh. To update the status automatically after a specific interval, in the Refresh every [...] seconds box, enter the number of seconds.
5. To stop an N+1 node, select the node, click Stop Node, and then do the following:
a) Select how you want to handle current activities on the DS-System. Your options are as follows:
• Wait for all running activities to complete – Stops the DS-System on the selected node after all current activities are completed.
• Stop when all activities complete or force stop after [...] minute(s): Stops the DS-System on the selected node after all current activities are completed or forces the activities to stop after a specified time.
b) Click OK. No new activities on the node will be allowed to run.
c) Click Close.
IMPORTANT: You cannot restart a stopped node from the DS-Operator. If you stop the DS-Director node, you must reconfigure the N+1 DS-System.
6. To delete an N+1 node, select the node, and then click Delete Node. When the system prompts you to confirm you want to delete the node, click Yes.
NOTE: The node is marked as deleted in the N+1 Cluster config file. You can only remove the last node in the list after stopping the DS-System service or daemon.
7. To view the current status of the N+1 DS-System configuration, click the Graph tab, and then do the following:
a) In the Graph Layout box, specify if you want to view the N+1 configuration in Linear or Star format.
b) To update the status of the N+1 configuration automatically after a specific interval, in the Refresh every [...] seconds box, enter the number of seconds.
8. Click Close.
