NAME

6       ndctl-zero-labels - zero out the label area on a dimm or set of dimms
7

SYNOPSIS

9       ndctl zero-labels <nmem0> [<nmem1>..<nmemN>] [<options>]
10

DESCRIPTION

12       The namespace label area is a small persistent partition of capacity
13       available on some NVDIMM devices. The label area is used to resolve
14       aliasing between pmem and blk capacity by delineating namespace
15       boundaries. This command resets the device to its default state by
16       deleting all labels.
17

OPTIONS

19       <memory device(s)>
20           One or more nmemX device names. The keyword all can be specified to
21           operate on every dimm in the system, optionally filtered by bus id
22           (see
23                  --bus= option).
24
25       -b, --bus=
26           Limit operation to memory devices (dimms) that are on the given
27           bus. Where bus can be a provider name or a bus id number.
28
29       -v
30           Turn on verbose debug messages in the library (if ndctl was built
31           with logging and debug enabled).
