Replacing Hardware Components in Your Quiver 2U Hybrid Gen2 Nodes

This section explains how to replace hardware components in Quiver 2U Hybrid Gen2 nodes.

For detailed hardware replacement instructions, see RSC-2MS Rackmount Chassis User’s Manual in the documentation provided to Qumulo by AIC.

Important
Before installing your Quiver 2UH Gen2 node in a server rack, you must remove the shipping screws from the node.

Removing and Replacing the Top Cover

Follow the instructions in the SC-2MS Rackmount Chassis User’s Manual: Top Cover (p. 13).

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. For more information, see NVMe M.2 Boot Drive.

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 HDD Drive

Your Quiver 2UH Gen2 chassis contains 24 HDDs. For more information about drive location and mapping, see Internal HDD Drives.

Replacing an NVMe Drive

Your Quiver 2UH Gen2 chassis contains 6 NVMe drives. For more information about drive location and mapping, see Rear NVMe Drives.

Replacing a Power Supply Unit (PSU)

Follow the instructions in the SC-2MS Rackmount Chassis User’s Manual: Power Supply Unit Module (p. 14).

Replacing a Fan Module

Follow the instructions in the SC-2MS Rackmount Chassis User’s Manual: Fan Module (p. 15).

To Replace the Node Chassis

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

Remove the existing HDD and NVMe drives, the boot drive, and the NIC from the chassis.
Install the existing components in the new chassis.
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).

Follow the prompts to complete the chassis replacement.
