NAME

       nvme-fw-log - Send NVMe Firmware log page request, returns result and log

SYNOPSIS

       nvme fw-log <device> [--raw-binary | -b]
                               [--output-format=<fmt> | -o <fmt>]

DESCRIPTION

       Retrieves the NVMe Firmware log page from an NVMe device and provides the returned
       structure.

       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 returned f/w 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 fw log buffer to stdout.

       -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

       •   Print the firmware log page in a human readable format:

               # nvme fw-log /dev/nvme0

       •   Print the log firmware to a file:

               # nvme fw-log /dev/nvme0 --raw-binary > fw_log.raw

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