nvme-effects-log - Man Page
Send NVMe Command Effects log page request, returns result and log
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, ā--human-readable
This option will parse and format many of the bit fields into a human-readable format.
- -b, ā--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
