lshw -class disk command lists all the disk devices in the system, providing details such as the model and the manufacturer, which can help to physically identify the device.

Exploring /dev/disk/: This directory contains symbolic links to all disks, organized by ID, label, UUID, and path. These links can help you identify the physical device based on various attributes.

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2. Get root privileges

sudo su -
