                        [--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
