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.
