NVME-LIST-SUBSYS(1) NVMe Manual NVME-LIST-SUBSYS(1) NAME nvme-list-subsys - List all NVMe subsystems SYNOPSIS nvme list-subsys <device> [--output-format=<fmt> | -o <fmt>] [--verbose | -v] DESCRIPTION Scan the sysfs tree for NVM Express subsystems and return the controllers for those subsystems as well as some pertinent information about them. If a device is given, print out only the values for the controllers and subsys- tems leading to the device. OPTIONS -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, --verbose Increase the information detail in the output.
