Replacement procedure for NVMe disks (SSDs)
NVMes are solid state drives (SSDs). The 7.68 TB NVMe RI drives are in slots 3 and 4 in the mid-bay.
To view the serial number of the NVMe disks, log in to the iLO remote console and click .
The following figures show the serial number for the two NVMe disks. Note the serial number of the NVMe disks. The serial number changes after the faulted disk is replaced.
In the NetBackup Flex Scale infrastructure management UI, navigate to . The disk status is shown faulted.
SSH to the the eth1 (management) IP address of the node and in the node-level CLI, run the following command to check the status of the NVMe disks:
show hardware-health node component=SSD
If there is some problem with the NVMes disks (7.68 TB capacity), in the Status column the disk status is shown NOT-OK.
Before an HPE representative can replace the NVMe disks, 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 faulted NVMe disk with another NVMe disk.
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:
- Restart the node from the iLO remote console using the Power > Momentary Press option.
- Confirm that the serial number of the NVMe disk is updated. After an NVMe disk is replaced, the serial number is different from the one that you noted earlier.
- SSH to the eth1 (management) IP address of the node and run the show hardware-health node component=SSD command in the node-level CLI. In the Status column, the NVMe disk status is shown OK.
- In the NetBackup Flex Scale infrastructure management UI, replace the faulty NVMe disk with a new NVMe disk. If both the NMVe disks are faulty, replace with new disks successively. Navigate to Monitor > Infrastructure > Disks. Click the faulty disk that you want to replace, and then click Actions menu (vertical ellipsis) from the right side of the row in the UI and click Replace disk. The replacement disk is detected and added to the node.
After the disk is replaced, data rebuild process begins and you can monitor the progress at the bottom of the screen when you click Infrastructure > Monitor > Disks. Time taken to rebuild the data depends on the amount of data.
