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>] [--verbose | -v]

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

   -v, --verbose
       Increase the information detail in the output.

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.
