Replacing Hardware Components in Your Quiver 1U All-NVMe Gen1 Nodes

This section explains how to replace hardware components in Quiver 1U All-NVMe Gen1 nodes.

To Remove and Replace the Top Cover

Follow the instructions in the ASUS documentation:

Remove the rear cover.
Remove the backplane cover.
Remove the air ducts.
When reassembling the chassis, follow these instructions in reverse order.

Replacing a NIC

Note
Certain node types have two NICs. For more information, see Technical Specifications.

Follow the instructions in the ASUS documentation:

For the left NIC, see Installing an Expansion Card to the Butterfly Riser Card Bracket.
For the right NIC, see Installing an Expansion Card to the Riser Card Bracket.

Replacing an M.2 Boot Drive

The boot drive is located at the M.2 expansion slot at connector NGFF1. For more information, see Installing M.2 (NGFF) Cards in the ASUS documentation.

Initializing the Replacement Boot Drive

After you replace the boot drive, you must initialize the replacement boot drive by using the Qumulo Core Installer and then rebuild the replacement boot drive by using a script on the node in your cluster.

Step 1: Initialize the Replacement Boot Drive

Tip
To get the correct version of the Qumulo Core Installer for the node in your cluster, contact the Qumulo Care team

Create a Qumulo Core USB Drive Installer.
Power on your node, enter the boot menu, and select your USB drive.

The Qumulo Core Installer begins to run automatically.
When prompted, take the following steps:
1. Select [x] Perform maintenance.
2. Select [1] Boot drive reset and then follow the prompts.
The Qumulo Core Installer initializes the boot drive.
When the process is complete, the node is powered down automatically.

Step 2: Rebuild the Replacement Boot Drive

Power on your node and log in to the node by using the qq CLI.
To get root privileges, run the sudo qsh command.
To stop the Qumulo Networking Services, run the service qumulo-networking stop command.
To configure the IP address for the node, run the ip addr add command and specify the node’s IP address. For example:
```
ip addr add 203.0.113.0/CDR dev bond0
```
Ensure that the node can ping other nodes in the cluster.
Run the rebuild_boot_drive.py script and specify the IP address of another node in the cluster, the ID of the node whose boot drive has been replaced, and the password of the administrative account of the cluster. For example:

Note
If your password includes special characters such as the parenthesis (() or the asterisk (*), use the backslash (\) to escape these characters.
```
/opt/qumulo/rebuild_boot_drive.py \
  --address 203.0.113.1 \
  --node-id 2 \
  --username admin \
  --password my\(Special\*Password
```
Follow the prompts.
When the process is complete, reboot the node.

Replacing an NVMe Drive in a Front Storage Bay

There are 12 2.5” hot-swap NVMe drives attached with four screws to trays in front storage bays. For more information, see Installing a 2.5-Inch Storage Device to a Front Storage Bay in the ASUS documentation.

Replacing an NVMe Drive in an Internal Storage Bay

There are 4 2.5” hot-swap NVMe drives in snap-in, toolless trays in internal storage bays. For more information, see Installing a 2.5-Inch Storage Device to an Internal Storage Bay in the ASUS documentation.

Replacing a Power Supply Unit (PSU)

Your Quiver 1UA Gen1 chassis contains two PSUs. Follow the instructions to replace a power supply module in the ASUS documentation.

To Replace a System Fan

Your Quiver 1UA Gen1 chassis has five system fans on the left and two on the right. The fans mount to the chassis with a toolless system. For more information, see Internal Features in the ASUS documentation.

Disconnect a fan from the motherboard. For more information, see Cable Connections and System Fan Connectors in the ASUS documentation.
To remove a fan, lift it upwards from the chassis.

Replacing a DIMM

Your Quiver 1UA Gen1 chassis has 24 DDR5 DIMM slots. For more information, see System Memory and Memory Configurations in the ASUS documentation.

Follow the instructions for removing and installing a DIMM in the ASUS documentation.

Replacing the Node Chassis

Important
After you perform a chassis swap, you must reconfigure the IPMI settings for your node.

Step 1: Remove the Existing Components

At the back of the node, disconnect the power cabling from both power supply units (PSUs) and remove both existing PSUs from the node.
Disconnect the network cabling from the NIC ports and remove the existing NICs from the node.
Remove the NVMe drives in front storage bays, the NVMe drives in internal storage bays, and the NVMe M.2 boot drive from the node.
Remove the existing chassis from the server rack.

Important
We strongly recommend using a server lift or that two people perform this task.

Step 2: Install New Components

Install the new chassis in the server rack.

Caution
To avoid warping the chassis frame, always keep it level while you insert it into the server rack. Never insert the chassis at an angle and don't apply excessive pressure to it.
Install the NVMe drives and the boot drive in the node.
Do one of the following:
- If your replacement chassis comes with NICs, install the new NICs in the chassis and connect the network cabling to the NIC ports.
- If your replacement chassis doesn’t come with NICs, install and connect the existing NICs.
For the PSUs, do one of the following:
- If your replacement chassis comes with PSUs, install the new PSUs in the chassis and connect the power cabling to the PSUs.
- If your replacement chassis doesn’t come with PSUs, install and connect the existing PSUs.
Boot by using the latest version of the Qumulo Core USB Drive Installer.
Select [*] Perform maintenance.
Select [2] Perform automatic repair after part replacement (non-destructive).

The part replacement procedure runs and the FVT passed! message appears.

Note
In some cases, after the part replacement procedure, the message FIX: Run the FVT flash command. appears. Enter 1 as you would for a fixable issue to reboot the node and then repeat the part replacement procedure.
