<nsid>] [−o <fmt> |
−−output−format=<fmt>]
DESCRIPTION
For the NVMe
device given, sends an identify command for controller list
and provides the result and returned structure. This uses
either mode
12h or 13h depending on the requested namespace
identifier.
The
<device> parameter is mandatory and may be either the
NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex:
/dev/nvme0n1).
The starting controller in the list always begins with 0
unless the
‘'−−cntid'‘ option is given to
override.
On success, the
controller array is printed for each index and controller
identifier.
OPTIONS
−c <cntid>, −−cntid=<cntid>
Retrieve the identify list structure starting with the given controller id.
−n <nsid>, −−namespace−id=<nsid>
If provided, will request the controllers attached to the specified namespace. If no namespace is given, or set to 0, the command requests the controller list for the entire subsystem, whether or not they are attached to namespace(s).
−o <format>, −−output−format=<format>
Set the reporting format to normal or json. Only one output format can be used at a time.
