Adding an excluded node to the cluster
A node is excluded from the cluster if the node reboots or panics multiple times. NetBackup Flex Scale monitors the cluster nodes and if a node reboots or panics five times, the node is excluded from the cluster. For a node that is excluded, the health of the node changes to unhealthy and node status is shown Excluded on the page of the NetBackup Flex Scale UI. All cluster services are stopped on an excluded node, similar to a stop node operation.
Note:
NetBackup Flex Scale automatically detects and sets the node status to Excluded if there are multiple occurrences of a node rebooting or going in a panic state. You do not have the option to set the node status to Excluded.
You can include the excluded node back to the cluster. When you include an excluded node, all services that are stopped on the node are restarted.
To include an excluded node:
- Use any one of the following options to log on using the user account that you created when you configured the cluster:
Use a user account with both Appliance administrator and NetBackup Administrator role, or a user account with only an Appliance administrator role to log on to the NetBackup Flex Scale web UI
https://ManagementServerIPorFQDN/webuiwhere ManagementServerIPorFQDN is the public IP address, the FQDN, or the short host name that you specified for the NetBackup Flex Scale management server during the cluster configuration, and then in the left pane click Cluster Management > Infrastructure > Nodes.Use a user account with an Appliance Administrator role to log on to the NetBackup Flex Scale infrastructure management UI
https://ManagementServerIPorFQDN:14161where ManagementServerIPorFQDN is the public IP address, the FQDN, or the short host name that you specified for the NetBackup Flex Scale management server during the cluster configuration, and then in the left pane click Monitor > Infrastructure > Nodes.
- To include the excluded node, click the Actions menu (vertical ellipsis) from the right side of the row in the UI and click Include node.
A notification is displayed on top of the page.
- To monitor the progress, click View details. Alternatively, you can also click the Recent Activity icon from the top right of the UI to see the status of the most recent operations occurring in the cluster.
