Replacement procedure for RAID controller
The following figures show the serial number for the RAID controller. Note the serial number of the RAID controller before replacement. The serial number changes after the RAID controller is replaced.
To view the serial number of the RAID controller, log in to the iLO remote console and click .
Before an HPE representative can replace the RAID controller, you must shut down the node.
To shut down the node:
- Sign in to the NetBackup Flex Scale infrastructure management UI and navigate to Monitor > Infrastructure > Nodes.
- On the node where the failure occurred, click the Actions menu (vertical ellipsis) from the right side of the row in the UI 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.
The HPE representative replaces the RAID controller.
After the hardware vendor notifies you that the hardware component is replaced, verify that the issue is resolved.
To verify that the issue is resolved, complete the following steps:
- Power on the server and wait till the node joins the cluster.
- Verify the state and serial number of the RAID controller in the iLO remote console.
- Verify that the node status in the NetBackup Flex Scale infrastructure management UI is shown healthy.
- After the node joins the cluster, to avoid the data corruption replace that node. When the controller is replaced, the write data is lost as there is no way to move the Flash Backed Write Cache (FBWC) from one controller to another controller.
Shut down the node. Navigate to Monitor > Infrastructure > Nodes. Click the Actions menu (vertical ellipsis) from the right side of the row in the UI and click Shutdown node.
The node is shown unhealthy after you shut down the 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.
- Prepare the node for replacement:
Deploy the ISO on the node that was shut down.
Perform factory reset on that node from the node-level CLI by using the system factory-reset command.
- From the NetBackup Flex Scale infrastructure management UI perform the replace node operation.
Scan for nodes. Click Scan for nodes to discover the nodes.
Select a node from the displayed list and replace the node. For the unhealthy node, click the Actions menu (vertical ellipsis) from the right side of the row in the UI, and click Replace node.
In the Replace node dialog box, select the node that you want to use to replace the unhealthy node and click Replace node.
- After the replace node operation completes successfully check the node status in the NetBackup Flex Scale infrastructure management UI. Navigate to Monitor > Infrastructure > Nodes. The node is online and shown healthy
Click Dashboard and verify that all the NetBackup services are running.
