Replacement procedure for a chassis fan
This topic describes the process for replacing a chassis fan in a NetBackup Flex Scale node. Each node contains six fans.
The following section describes how to identify a chassis fan failure from NetBackup Flex Scale:
An alert is generated for the node where the fan is malfunctioning. To view the alert, do one of the following from the NetBackup Flex Scale infrastructure management UI:
Click in the left pane. In the Alerts area, click to see a complete list of alerts.
At the top of any screen, click the icon.
Click . On the Alerts and notifications page, use the filters to locate specific types of alerts.
Note:
If Call Home is configured for your setup, diagnostic information is sent to the AutoSupport server.
The node where the fan malfunctions is shown as Unhealthy. In the NetBackup Flex Scale infrastructure management UI, navigate to to view the health of the nodes.
Navigate to , click the node that is unhealthy and for which the alert was generated, and then click . The state of the fan is shown as Failed.
The following section describes how to identify a chassis fan failure from third-party tools:
The HPE Integrated Lights-Out (iLO) remote console shows a failure. Navigate to and note the details in the Summary section for malfunctioning fan.
You need to shut down the node on which the fan is malfunctioning. For a cluster with fewer than six nodes, only a single node can be down, stopped, or shut down at any given point in time. For a larger cluster of up to 16 nodes, a maximum of two nodes can be down, stopped, or shut down at any given point in time. When you shut down a node, the cluster services running on the node are stopped and the NetBackup jobs running on the node fail over to other cluster nodes. After the hardware maintenance is complete, you need to turn on 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. If you shut down the node where the NetBackup Flex Scale infrastructure management UI is running, it fails over to another node. It can take a few minutes for the UI to be up on another node.
Note:
If the loss of nodes exceeds the supported fault tolerance, either due to node failures or because the nodes are stopped or shut down, the cluster goes in an inconsistent state.
To shut down the node:
- Shut down the node where the chassis fan failed. Navigate to Monitor > Infrastructure > Nodes and click Shutdown node.
- Confirm that the node is shut down successfully. In the UI, you can view the notification at the top of the page. In the iLO remote console, wait until the system shows the System halted message.
- Shut down the node. Press the Power button on the front panel of the server or from the iLO remote console use the Server Power > Press and Hold option.
- Contact the hardware vendor to replace the hardware component.
The HPE representative replaces the chassis fan.
After the hardware vendor notifies you that the hardware component is replaced, verify that the issue is resolved.
Power on the server from the iLO remote console using the option and wait till it joins the cluster.
Check the node status and the services status in the NetBackup Flex Scale infrastructure management UI:
Verify the fan status in the NetBackup Flex Scale infrastructure management UI. Navigate to .
Verify the fan status in the iLO remote console. Navigate to .
