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.
