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 • 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. NVME Part of the nvme-user suite NVMe 10/31/2024 NVME-ERROR-LOG(1)
