representation of a physical point in the system where +components can be inserted or removed. +A hotplug port is a representation of a logical point in the system device tree +where the connection of a device to the system is managed. +.Pp +The +.Nm +command only supports hotplug operations on hotplug connectors for PCI Express +buses and PCI buses that implement the Standard PCI Hotplug feature. +Hotplug ports on PCI Express and PCI buses in systems with PCI Express fabrics +are also supported. +Additional buses may be supported in the future. +.Pp +The +.Nm +command operates on the following kinds of objects: +.Bl -tag -width "connection" +.It Cm path +Hotplug connectors and ports are integrated into the system device tree. +The names of connectors and ports are unique relative only to their bus +controller. +A device path is required to uniquely reference a connector or port. +.It Cm connector +If a hardware component supports being physically inserted or removed, then a +hotplug connector represents the location where this action may occur. +When a connector exists, it has a hierarchy of ports and device nodes that +depend upon it. +.It Cm port +All device nodes can be virtually hotplugged, even if their hardware does not +support physical hotplugging. +A hotplug port exists between a device node and its parent node in the system +device tree. +It represents the location where the device node and its dependents can be +managed. +.It Cm connection +A hotplug connection is a generic term to refer to either a hotplug connector or +a hotplug port. +.El +.Pp +Hotplug connectors and ports are managed according to a state model. +The +.Nm +command can list information about the hotplug connections in a system, or it +can initiate change of state operations on specific hotplug connections. +.Pp +Hotplug connectors can be in the following states: +.Bl -tag -width "present" +.It Cm empty +A component is not physically inserted in the connector. +.It Cm present +A component is physically inserted in the connector, but the component is +powered off. +The component is not in use. +.It Cm powered +A component is physically inserted in the connector, and the component is +powered on. +The component is disabled and is not in use. +.It Cm enabled +A component is physically inserted in the connector. +The component is powered on and has been probed and tested. +The component is enabled and devices that represent its functions can be used. +.El +.Pp +Hotplug ports can be in the following states: +.Bl -tag -width "port-present" +.It Cm port-empty +No device exists for the hotplug port. +.It Cm port-present +A device exists for the hotplug port, but the device has not been probed and it +has no attached device driver. +The device is not in use. +.It Cm offline +A device exists for the hotplug port, and the device has been probed. +A device driver is not attached, and the device is not in use. +.It Cm online +A device exists for the hotplug port, and its device driver is fully attached. +The device is in use. +.It Cm maintenance +A device exists for the hotplug port, and its device driver is fully attached. +The device is in use, but not fully operational. +A maintenance or fault management operation is affecting the device. +.El +.Pp +The +.Nm +command can also access bus private properties for each hotplug connector. +The current values of bus private properties can be displayed. +New values for each bus private property can be set directly. +.Sh EXIT STATUS +.Bl -diag +.It 0 +Successful completion. +.It 1 +Invalid command line options were specified. +.It 2 +The specified path or connection does not exist. +.It 3 +A fatal error occurred. +One or more error messages are displayed on standard error. +.It 4 +The hotplug service is not available. +.El +.Sh EXAMPLES +.Bl -tag -width 0n +.It Sy Example 1 No Showing All Hotplug Connections +The following command shows all hotplug connections: +.Bd -literal +# hotplug

+To show the full paths of hotplug connections and devices, enter the following +command: +.Bd -literal +# hotplug list -l +/pci@0,0 <pci.2,1> (ONLINE) +/pci@0,0/pci108e,534a@2,1 [pci30] (EMPTY)

+/pci@0,0/pci108e,534a@4 +.Ed +.It Sy Example 2 No Reporting Failure During State Change Operation +If a change of state operation fails, an explanation is displayed to describe +the failure. +An attempt to offline a hotplug port with dependent devices that are currently +in use by the system might fail as follows: +.Bd -literal +# hotplug offline /pci@0,0/pci10de,5d@e pci.a,0 +ERROR: devices or resources are busy. +pci108e,534a@a,0: + { Network interface nge0 } + { nge0: hosts IP addresses: 10.0.0.1 } + { Plumbed IP Address } +.Ed +.It Sy Example 3 No Displaying Bus-Specific Properties

+fault_led=<on|off|blink> +active_led=<on|off|blink> +attn_led=<on|off|blink> +card_type=<type description> +board_type=<type description> +.Ed +.It Sy Example 4 Displaying Bus-Specific Options +The following command displays the card type and the current state of the Power +LED of a PCI hotplug connector: +.Bd -literal +# hotplug get -o card_type,power_led /pci@0,0 pci.2,1 +card_type=fibre +power_led=on +.Ed +.It Sy Example 5 No Setting a Bus-Specific Property +The following command turns on the attention LED of a PCI hotplug connector: +.Bd -literal +# hotplug set -o attn_led=on /pci@0,0 pci.2,1 +.Ed +.El +.Sh DIAGNOSTICS +The following error message is displayed on systems that do not have any +supported I/O buses: +.Bd -literal +ERROR: there are no connections to display. +(See hotplug(1m) for more information.) +.Ed +.Pp +If this error message is seen, note that the system might still have other I/O +devices that support hotplugging, through the +.Xr cfgadm 1M
