NAME
       ndctl-zero-labels - zero out the label area on a dimm or set of dimms


SYNOPSIS
       ndctl zero-labels <nmem0> [<nmem1>..<nmemN>] [<options>]


DESCRIPTION
       The namespace label area is a small persistent partition of capacity available on some NVDIMM devices.
       The label area is used to resolve aliasing between pmem and blk capacity by delineating namespace
       boundaries. This command resets the device to its default state by deleting all labels.


OPTIONS
       <memory device(s)>
           One or more nmemX device names. The keyword all can be specified to operate on every dimm in the
           system, optionally filtered by bus id (see --bus= option).

       -b, --bus=
           Limit operation to memory devices (dimms) that are on the given bus. Where bus can be a provider name
           or a bus id number.

       -v
           Turn on verbose debug messages in the library (if ndctl was built with logging and debug enabled).
