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

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

A generic REGION device is registered for each PMEM range or BLK-aperture set. LIBNVDIMM provides a built-in driver for these REGION devices. This driver is responsible for reconciling the aliased DPA mappings across all regions, parsing the LABEL, if present, and then emitting NAMESPACE devices with the resolved/exclusive DPA-boundaries for the nd_pmem or nd_blk device driver to consume.

<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.
