This tool is inspired from lsidrivemap

Configuration

The tool can be configured using lsmap --reconfigure to make the correspondence between logical en physical layout.

Requirements

• The script requires Python 3 and python3-tabulate.

TODO

• Support for nvme drives.
• In the future the tool may also show the temperature of the drive (using hddtemp or similar tool).

Contributions are welcome!
