Parameters

WWPN The WWPN of the FC initiator port.

Target WWPN The WWPN of an FC port on an NVMe-capable device.

NQN The qualified name of the NVMe subsystem.

FeatureID The feature identifier:

0x1 = Arbitration

0x2 = Power management

0x3 = LBA range type

0x4 = Temperature threshold

0x5 = Error recovery

0x6 = Volatile write cache

0x7 = Number of queues

0x8 = Interrupt coalescing (not supported)

0x9 = Interrupt vector configuration (not supported)

0xA = Write atomicity normal

0xB = Asynchronous event configuration

0xC = Autonomous power state transition

0xD = Host memory buffer

0xF = Keep alive timer

0x80 = Software progress marker (optional feature)

0x81 = Host identifier (mandatory feature)

0x82 = Reservation notification mask (optional feature)

0x83 = Reservation persistence (optional feature)

ctrlid The controller that processes the request (optional), in hexadecimal.

raw Specifies that the output is to be provided in hexadecimal format if the feature returns a data structure; ignored if no data

structure is returned (optional).

select The attribute value to be returned (optional):

0 = Current

1 = Default

2 = Saved

3 = Supported capabilities:

 Savable: You can change the value, and the value persists after a controller reset. If a value is not savable, you can

change the value, but the value will not persist after a controller reset.

 Changeable: You can save the feature using the SetFeature command (not currently supported).

 Namespace specific: The FeatureID is specific to the namespace identified in the command line by nsid.

If no Select parameter is specified, the output contains the current, default, and saved values for the selected feature

and the supported capabilities of the feature.

Some Select parameter attribute values may not be available on all targets. To determine the level of support for the

Select parameter, issue the nvme-id-ctrl command and examine the value displayed for Non-zero feature

Select option. If the value is Not Supported, the only allowed value for the Select parameter is 0 (current). An

attempt to enter a nonzero value for the Select parameter results in an Invalid Argument error. Additionally, if no

Select parameter is specified, only the current value for the selected feature is presented.

nsid The namespace for which a feature is to be retrieved.

vector The interrupt vector for which the configuration settings are to be retrieved, in hexadecimal. Valid values are 0x0 to 0xffff.

This applies only to the interrupt vector configuration feature (FeatureID=0x9).
