nvme-list-subsys(1) =================== NAME ---- nvme-list-subsys - List all NVMe subsystems SYNOPSIS -------- [verse] 'nvme list-subsys' [-o | --output-format=] 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 subsystems leading to the device. OPTIONS ------- -o :: --output-format=:: Set the reporting format to 'normal' or 'json'. Only one output format can be used at a time.
