NVME-CHANGED-NS-L(1) NVMe Manual NVME-CHANGED-NS-L(1)

NAME

nvme-changed-ns-list-log - Send NVMe Changed Namespace List log page request, returns result and log.

SYNOPSIS

nvme [<global-options>] changed-ns-list-log <device> [--raw-binary | -b]

DESCRIPTION

Retrieves the NVMe Changed Namespace List log page from an NVMe device and provides the returned structure.

The <device> parameter is mandatory and must be a NVMe character device (ex: /dev/nvme0).

On success, the returned Changed Namespace List log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse.

OPTIONS

-b, --raw-binary

Print the raw Changed Namespace List log buffer to stdout.

GLOBAL OPTIONS

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o <fmt>, --output-format=<fmt>

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

--output-format-version=<version>

Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.

--timeout=<ms>

Set the timeout for the command in milliseconds.

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file.

EXAMPLES

•Print the Changed Namespace List Log page in a human readable format: 

# nvme changed-ns-list-log /dev/nvme0

•Print the raw Changed Namespace List log to a file: 

# nvme changed-ns-list-log /dev/nvme0 --raw-binary > log.raw

It is probably a bad idea to not redirect stdout when using this mode.
