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).
