Description

Reads and shows the defined NVMe controller property for NVMe over Fabric.

Options

-O <offset>, --offset=<offset>

The offset of the property. One of CAP=0x0, VS=0x8, CC=0x14, CSTS=0x1c, NSSR=0x20

-H

--human-readable: Show the fields packed in the property

-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, ā€‰--verbose

Increase the information detail in the output.

-t <timeout>, --timeout=<timeout>

Override default timeout value. In milliseconds.

Examples

Bugs

Currently the CAP value is truncated to 32 bits due to a limitation in the ioctl interface.

In a recent enough kernel, the 64 bit value is shown in kernel traces.
