## NAME

ndctl − Manage "libnvdimm" subsystem devices (Non−volatile Memory)

## SYNOPSIS

*ndctl* \[−−version] \[−−help] \[OPTIONS] COMMAND \[ARGS]

## OPTIONS

−v, −−version

Display ndctl version.

−h, −−help

Run ndctl help command.

## DESCRIPTION

ndctl is utility for managing the "libnvdimm" kernel subsystem. The "libnvdimm" subsystem defines a kernel device model and control message interface for platform NVDIMM resources like those defined by the ACPI 6.0 NFIT (NVDIMM Firmware Interface Table). Operations supported by the tool include, provisioning capacity (namespaces), as well as enumerating/enabling/disabling the devices (dimms, regions, namespaces) associated with an NVDIMM bus.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pmem.io/ndctl-user-guide/v66/ndctl-man-pages/untitled.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
