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

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.
