NVME-LOG-CHANGED-(1)              NVMe Manual             NVME-LOG-CHANGED-(1)

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

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

DESCRIPTION
       Retrieves the NVMe Changed Allocated 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 Allocated 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
       o   Print the Changed Allocated Namespace List Log page in a human
           readable format:

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

       o   Print the raw Changed Allocated Namespace List log to a file:

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

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