How To Install NDCTL and DAXCTL Packages on Red Hat Enterprise Linux (RHEL) and CentOS 7

Applies To

This document applies to RHEL/CentOS 7.5 or later running Linux Kernel 3.10.0 or later.

Introduction

The ndctl utility is used to manage persistent memory devices within the system while the daxctl utility managed device-dax instances. libndctl is required for several Persistent Memory Development Kit (PMDK) and ipmctl features if compiling from source. If ndctl is not available, the PMDK may not build all components and features. This page describes how to install ndctl and daxctl using the Linux package repository.

Both ndctl and daxctl are Linux only utilities.

Installing NDCTL Packages

1. Query the repository to identify if ndctl is delivered:

   $ sudo apt search ndctl

2. Install the ndctl package. This automatically installs daxctl and libndctl.

   $ sudo apt-get install ndctl

3. Done!
