nvme-effects-log - Man Page

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

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.

-o <format>, --output-format=<format>

This option will set the reporting format to normal, json, or binary. Only one output format can be used at a time.

-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.

• 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
