NAME

6       ndctl-check-labels - determine if the given dimms have a valid
7       namespace index block
8

SYNOPSIS

10       ndctl check-labels <nmem0> [<nmem1>..<nmemN>] [<options>]
11

DESCRIPTION

13       The namespace label area is a small persistent partition of capacity
14       available on some NVDIMM devices. The label area is used to provision
15       one, or more, namespaces from regions. In addition to checking if a
16       label area has a valid index block, running this command in verbose
17       mode reports the reason the index block is deemed invalid.
18

OPTIONS

20       <memory device(s)>
21           A nmemX device name, or a dimm id number. Restrict the operation to
22           the specified dimm(s). The keyword all can be specified to indicate
23           the lack of any restriction, however this is the same as not
24           supplying a --dimm option at all.
25
26       -s, --size=
27           Limit the operation to the given number of bytes. A size of 0
28           indicates to operate over the entire label capacity.
29
30       -O, --offset=
31           Begin the operation at the given offset into the label area.
32
33       -b, --bus=
34           A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict
35           the operation to the specified bus(es). The keyword all can be
36           specified to indicate the lack of any restriction, however this is
37           the same as not supplying a --bus option at all.
38
39       -v
40           Turn on verbose debug messages in the library (if ndctl was built
41           with logging and debug enabled).
