nvme effects-log <device> [--human-readable | -H] [--raw-binary | -b]
                        [--output-format=<fmt> | -o <fmt>] [--verbose | -v]
                        [--timeout=<timeout> | -t <timeout>]

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
