SYNOPSIS

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

DESCRIPTION

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.

OPTIONS

-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.

EXAMPLES

  • 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
