Starting and stopping nodes
You might need to stop a cluster node for hardware maintenance such as replacing some of the hardware components. For a cluster with less than six nodes, only a single node can be down or you can stop only a single node at any given point in time. For a larger cluster, a maximum of two nodes can be down or can be stopped at any given point in time. When you stop a node, the NetBackup jobs running on the node fail over to other nodes in the cluster and the cluster services running on the node are stopped. After the hardware maintenance is complete, you need to start the node. When you start a node, the cluster services are started on the node, the node joins the cluster and can start running backup jobs.
At any given point in time, only a single node can be down or can be stopped in a cluster of up to five nodes. For a larger cluster of up to 16 nodes, two nodes can be stopped or can be down at any given point in time.
Note:
If the loss of nodes exceeds the supported fault tolerance, either due to node failures or nodes are stopped or shut down, the cluster goes in an inconsistent state.
To stop and start a node:
- Use any one of the following options to log in using the user account that you created when you configured the cluster:
Using an user account with an Appliance Administrator and NetBackup Administrator role, log in to the NetBackup web interface
https://ManagementServerIPorFQDN
where ManagementServerIPorFQDN is the public IP address that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration, and then in the left pane click Appliance management.Using an user account with an Appliance Administrator role, log in to the NetBackup Flex Scale web interface
https://ManagementServerIPorFQDN:14161
where ManagementServerIPorFQDN is the public IP address that you specified for the NetBackup Flex Scale management server and API gateway during the cluster configuration.
- In the left navigation bar, click Monitor and then click Infrastructure.
- Click the Nodes tab.
The list of cluster nodes is displayed.
- To stop the node, click the Actions menu (vertical ellipsis) from the right side of the row in the UI, and click Stop node.
The node status changes to unhealthy.
- To start the node, click the Actions menu (vertical ellipsis) from the right side of the row in the UI, and click Start node.
The node status changes to healthy.
