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>] [--verbose | -v]

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 <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.

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.
