Introduction to Naming of a Linux-based Data Disk

2024-11-01 09:12:26

The name of a Linux-based data disk is automatically assigned by the system. The naming rules are as follows:

l  X series data disks: The X series EVS disks are mounted using the NVMe protocol. Therefore, the devices are named as /dev/nvme*n1, for example, /dev/nvme0n1, /dev/nvme1n1, /dev/nvme2n1, and so on. If the system disk of a cloud server is an X series, the system disk is assigned /dev/nvme0n1 by default.

l  Non-x series data disks: A device is named as /dev/vd[a-z], for example, /dev/vda, /dev/vdb, /dev/vdc, and so on. If the system disk of a cloud server is not an X series, the system disk is assigned /dev/vda by default.

Operation Guide of Disk Partitions

When the disk capacity is smaller than 2 TB:

l  Initialising Windows-based Data Disks (Windows 2008)

l  Initialising Windows-based Data Disks (Windows 2019)

l  Initialising Linux-based Data Disks (fdisk)

l  Initialising Linux-based Data Disks (parted)

When the disk capacity is greater than 2 TB:

l  Capacity Greater than 2 TB, Initialising Windows-based Data Disks (Windows 2008)

l  Capacity Greater than 2 TB, Initialising Windows-based Data Disks (Windows 2012)

Capacity Greater than 2 TB, Initialising Linux-based Data Disks (parted)
