NDCTL-CHECK-LABELS(1)

NAME

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

SYNOPSIS

ndctl check-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. In addition to checking if a label area has a valid index block, running this command in verbose mode reports the reason the index block is deemed invalid.

OPTIONS

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).
