NAME

       nvme-error-log - Send NVME Error log page request, return result and log

SYNOPSIS

       nvme error-log <device>  [--namespace-id=<nsid> | -n <nsid>]
                                [--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 retuned 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

       -n <nsid>, --namespace-id=<nsid>
           Retrieve the Error Log for the given nsid. This is optional and its success may depend
           on the device’s capabilities to provide this log on a per-namespace basis (see the
           NVMe Identify Controller for this capability). The default nsid to use is 0xffffffff
           for the device global error log.

       -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.
