Retrieves the NVMe Command Effects log page from an NVMe device and provides the returned structure.
The <device> parameter is mandatory and should be the NVMe character device (ex: /dev/nvme0).
On success, the returned command effects log structure will be printed for each command that is supported.
−H, −−human−readable
This option will parse and format many of the bit fields into a human−readable format.
−b, −−raw−binary
This option will print the raw buffer to stdout. Structure is not parsed by program. This overrides the human−readable option.
−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.
−t <timeout>, −−timeout=<timeout>
Override default timeout value. In milliseconds.
• Print the effects log page in a human readable format:
# nvme effects−log /dev/nvme0
• Have the program return the raw structure in binary:
# nvme
effects−log /dev/nvme0 −−raw−binary
> effects_log.raw
# nvme effects−log /dev/nvme0 −b >
effects_log.raw
