NVME-ERROR-LOG(1)                 NVMe Manual                NVME-ERROR-LOG(1)

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
       o   Get the error log and print it in a human readable format:

               # nvme error-log /dev/nvme0

       o   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.
