Formatting an SSD

Formatting an SSD


This command is used to format an SSD. Secure formatting and quick formatting are supported.


hioadm format -d devicename [-m formatmode] [-t lbasize]


Parameter Description Value
devicename Name of an SSD. Example: nvme0
formatmode Formatting mode.
  • 0: quick formatting (Secure Erase Settings=0)
  • 1: secure formatting (Secure Erase Settings=1)

If this parameter is not specified, the default value 0 is used.

lbasize Sector size and type.
  • 0: The sector size is 512 B, and the metadata size is 0 B.
  • 1: The sector size is 4 KB, and the metadata size is 0 B.
  • 2: The sector size is 512 B, and the metadata size is 8 B.

If this parameter is not specified, the sector size and type are not changed.

  • Linux and Windows support the preceding values. ESXi supports only the value 0. If this parameter is not specified, the sector size and type are not changed.
  • In the ES3000 V3 series, an SSD with a capacity greater than 4 TB does not support 512B sectors.

Usage Guidelines

  • Before running this command, stop all I/O services of the SSD and perform the following:
    • For Linux, unmount all logical disks. Stop all the processes on the logical disks that use the SSD, and run the fuser command to check that these processes are all stopped. The following information (in this example, the SSD has two logical disks) indicates that a process is using an SSD logical disk. Stop the process.
      [root@localhost tool]# fuser /dev/nvme0n1 /dev/nvme0n2
      /dev/nvme0n1:        14789
      /dev/nvme0n1:        14812
    • For ESXi, delete all partitions of all logical disks.
    • For Windows, make all logical disks offline, as shown in Figure 6-2.
      Figure 6-2  Making a logical disk offline

  • Do not read or write data when running this command. Otherwise, I/O errors may occur.


# Perform secure formatting of the nvme0 SSD, and set the sector size to 512 B and metadata size to 0 B.
