nvme self-test-log <device> [--log-entries=<entries> | -e <entries>]
                        [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

Retrieves the log pages from an NVMe device corresponding to the requested self-test by the user and provides 20-most recent result returned structure​.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)​.

On success, the returned log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer or the json format​.

By default the log is printed out in the normal readable format​.

-e <entries>, --log-entries=<entries>

Specifies how many DST log entries the program should request from the device​. This must be at least one, and shouldn’t exceed the 20 entries​. Defaults to 20 DST log entries​.

-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​.

• Get the self-test-log and print it in a human readable format:

  # nvme self-test-log /dev/nvme0

• Print the raw output to a file:

  # nvme self-test-log /dev/nvme0 -o "binary"

• Get the self-test-log and print it in a json format:

  # nvme self-test-log /dev/nvme0 -o "json"
