# ndctl-enable-region(1)

enable the given region(s) and all descendant namespaces

## NAME

ndctl-enable-region - enable the given region(s) and all descendant namespaces

## SYNOPSIS

```
ndctl enable-region <region> [<options>]
```

## DESCRIPTION

A generic REGION device is registered for each PMEM range / interleave-set. LIBNVDIMM provides a built-in driver for these REGION devices. This driver is responsible for parsing namespace labels and instantiating PMEM namespaces for each coherent set of labels.

## OPTIONS

\<region\>

A *regionX* device name, or a region id number. Restrict the operation to the specified region(s). The keyword *all* can be specified to indicate the lack of any restriction, however this is the same as not supplying a --region option at all.

\-b, --bus=

A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict the operation to the specified bus(es). The keyword *all* can be specified to indicate the lack of any restriction, however this is the same as not supplying a --bus option at all.
