nvme-fw-log – Send NVMe Firmware log page request, returns result and log
Synopsis
nvme fw-log <device> [–raw-binary | -b]
Description
Retrieves the NVMe Firmware log page from an NVMe device and provides the retuned 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.
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.
