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