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 provision one, or more, namespaces from regions.
       This command resets the device to its default state by deleting all labels.

OPTIONS

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

       -s, --size=
           Limit the operation to the given number of bytes. A size of 0 indicates to operate
           over the entire label capacity.

       -O, --offset=
           Begin the operation at the given offset into the label area.

       -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.

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