nvme-fw-log - Send NVMe Firmware log page request, returns result and log
nvme fw-log <device> [--raw-binary | -b]
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.
- Print the raw fw log buffer to stdout.
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.
