## NAME

nvme-nvm-id-ns-lba-format - Send NVMe Identify NVM Command Set specific Namespace data structure for specified LBA format, display structure

## SYNOPSIS

    nvme nvm-id-ns-lba-format <device> [--uuid-index=<uuid-index> | -U <uuid_index>]
                            [--lba-format-index=<lba_format_index> | -i <lba_format_index>]
                            [-v | --verbose]
                            [--output-format=<fmt> | -o <fmt>]

## DESCRIPTION

Identify NVM Command Set specific Namespace data structure for the specified LBA format index for the NVM Command Set specified in the CSI field.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout.

## OPTIONS

-U <uuid-index>
--uuid-index=<uuid-index>

  UUID Index of the feature

-i <lba_format_index>
--lba-format-index=<lba_format_index>

  This field specifies the index into the LBA Format list identifying the LBA Format capabilities that are to be returned

-v
--verbose

  Increase the information detail in the output.

-o <format>
--output-format=<format>

  Set the reporting format to normal, json, or binary. Only one output format can be used at a time.

## EXAMPLES

- Has the program interpret the returned buffer and display the known fields in a human readable format:

      # nvme nvm-id-ns-lba-format /dev/nvme0n1 -i 0

- Have the program return the raw structure in binary:

      # nvme nvm-id-ns-lba-format /dev/nvme0 -i 0 -o binary > nvm_id_ns.raw
      # nvme nvm-id-ns-lba-format /dev/nvme0n1 -i 0 --output-format=binary > nvm_id_ns.raw
