NAME
nvme-error-log - Send NVME Error log page request, return result and log
SYNOPSIS
nvme error-log <device> [--log-entries=<entries> | -e <entries>] [--raw-binary | -b] [--output-format=<fmt> | -o <fmt>]
DESCRIPTION
Retrieves NVMe Error log page from an NVMe device and provides the 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 error 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 may be printed to stdout for another program to parse.
OPTIONS
-e <entries>, --log-entries=<entries> Specifies how many log entries the program should request from the device. This must be at least one, and shouldn’t exceed the device’s capabilities. Defaults to 64 log entries. -b, --raw-binary Print the raw error log buffer to stdout. -o <format>, --output-format=<format> Set the reporting format to normal, json, or binary. Only one output format can be used at a time.
EXAMPLES
• Get the error log and print it in a human readable format: # nvme error-log /dev/nvme0 • Print the raw output to a file: # nvme error-log /dev/nvme0 --raw-binary > error_log.raw It is probably a bad idea to not redirect stdout when using this mode.
