nvme-dapustor-smart-log-add - Man Page

nvme dapustor smart-log-add <device> [--namespace-id=<nsid> | -n <nsid>]
                        [--raw-binary | -b] [--json | -j]

Retrieves the NVMe DapuStor Additional SMART log page from the 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 smart 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 Additional SMART 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 SMART log.

-b,  --raw-binary

Print the raw DapuStor Additional SMART log buffer to stdout.

-j,  --json

Dump output in json format.

• Print the DapuStor Additional SMART log page in a human readable format:

  # nvme dapustor smart-log-add /dev/nvme0

• Print the raw DapuStor Additional SMART log to a file:

  # nvme dapustor smart-log-add /dev/nvme0 --raw-binary > smart_log.raw

  It is probably a bad idea to not redirect stdout when using this mode.
