nvme-error-log - Send NVME Error log page request, return result and log
nvme error-log <device> [--namespace-id=<nsid> | -n <nsid>] [--log-entries=<entries> | -e <entries>] [--raw-binary | -b]
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.
-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.
• 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.
