nvmecontrol: New commands to support Fabrics hosts - discover: Connects to a remote Discovery controller, fetches its Discovery Log Page, and enumerates the remote controllers described in the log page. The -v option can be used to display the Identify Controller data structure for the Discovery controller. This is only really useful for debugging. - connect: Connects to a remote I/O controller and establishes an association of an admin queue and a single I/O queue. The association is handed off to the in-kernel host to create a new nvmeX device. - connect-all: Connects to a Discovery controller and attempts to create an association with each I/O controller enumerated in the Discovery controller's Discovery Log Page. - reconnect: Establishes a new association with a remote I/O controller for an existing nvmeX device. This can be used to restore access to a remote I/O controller after the loss of a prior association due to a transport error, controller reboot, etc. - disconnect: Deletes one or more nvmeX devices after detaching its namespaces and terminating any active associations. The devices to delete can be identified by either a nvmeX device name or the NQN of the remote controller. - disconnect-all: Deletes all active associations with remote controllers.
