cfgadm_pci - PCI Hotplug hardware specific commands for cfgadm SYNOPSIS
/usr/sbin/cfgadm [-f ] [-y | -n ] [-v] [-o hardware_options] -c function ap_id [ap_id] /usr/sbin/cfgadm [-f ] [-y | -n ] [-v] [-o hardware_options] -x hardware_function ap_id [ap_id] /usr/sbin/cfgadm [-v] [-s listing_options] [-o hardware_options] [-l [ ap_id | ap_type]] /usr/sbin/cfgadm [-v] [-o harware_options] -t ap_id [ap_id] /usr/sbin/cfgadm [-v] [-o hardware_function] -h [ ap_id| ap_type] DESCRIPTION
The PCI hardware specific library /usr/lib/cfgadm/pci.so.1 provides the support for hot plugging pci adapter cards into pci hot pluggable slots in a system that is hot plug capable, through the cfgadm command. See cfgadm(1M). For PCI Hot Plug, each hot plug slot on a specific PCI bus is represented by an attachment point of that specific PCI bus. An attachment point consist of two parts: a receptacle and an occupant. The receptacle under PCI hot plug is usually referred to as the physical hot pluggable slot; and the occupant is usually referred to as the PCI adapter card that plugs into the slot. Attachment points are named through ap_ids. There are two types of ap_ids: logical and physical. The physical ap_id is based on the physi- cal pathname, that is, /devices/pci@1/hpc0_slot3, whereas the logical ap_id is a shorter, and more user-friendly name. For PCI hot plug- gable slots, the logical ap_id is usually the corresponding hot plug controller driver name plus the logical slot number, that is, pci0:hpc0slot1; pci nexus driver, with hot plug controller driver named hpc and slot number 1. The ap_type for Hot plug PCI is pci. Note that the ap_type is not the same as the information in the Type field. See the System Administration Guide: Basic Administration for a detailed description of the hot plug procedure. OPTIONS
The following options are supported: -c function The following functions are supported for PCI hot pluggable slots: configure Configure the PCI device in the slot to be used by Solaris. connect Connect the slot to PCI bus. disconnect Disconnect the slot from the PCI bus. insert Not supported. remove Not supported. unconfigure Logically remove the PCI device's resources from the system. -f Not supported. -h ap_id | ap_type Print out PCI hot plug specific help message. -l list List the values of PCI Hot Plug slots. -o hardware_options No hardware specific options are currently defined. -s listing_options Same as the generic cfgadm(1M). -t ap_id This command is only supported on platforms which support testing capability on the slot. -v Execute in verbose mode. When -v is used with -l option the cfgadm command outputs information about the attachment point. For PCI Hot Plug, the Information field will be the slot's system label. This string will be obtained from the slot-name property of the slot's bus node. The information in the Type field is printed with or without the -v option. The occupant Type field will describe the contents of the slot. There are 2 possible values: unknown The slot is empty. If a card is in the slot, the card is not configured or there is no driver for the device on the card. subclass/board The card in the slot is either a single-function or multi-function device. subclass is a string representing the subclass code of the device, for example, SCSI, ethernet, pci-isa, and so forth. If the card is a multi-functional device, MULT will get printed instead. board is a string representing the board type of the device. For example, hp is the string used for a PCI Hot Plug adapter, hs is used for a Hot Swap Board, nhs for a Non--Hot Swap cPCI Board, bhs for a Basic Hot Swap cPCI Board, and fhs for a Full Hot Swap cPCI Board. Most pci cards with more than one device are not multi-function devices, but are implemented as a pci bridges with arbitrary devices behind them. In those cases, the subclass displayed is that of the pci bridge. Most com- monly the bridges are pci-pci, a generic pci to pci bridge or stpci, a semi-transparent pci bridge. -x hardware_function Perform hardware specific function. These hardware specific functions should not normally change the state of a receptacle or occupant. The following hardware_functions are supported: enable_slot | disable_slot Change the state of the slot and preserve the state of slot across reboot. Preservation of state across reboot is only supported on select platforms. enable_slot enables the addition of hardware to this slot for hot plugging and at boot time. disable_slot disables the addition of hardware to this slot for hot plugging and at boot time. When a slot is disabled its condi- tion is shown as unusable. enable_autoconfig | disable_autoconfig Change the ability to autoconfigure the occupant of the slot. Only platforms that support auto configuration support this feature. enable_autoconfig enables the ability to autoconfigure the slot. diable_autoconfig disables the ability to autoconfigure the slot. led=[led_sub_arg],mode=[mode_sub_arg] Without sub-arguments, print a list of the current LED settings. With sub-arguments, set the mode of a specific LED for a slot. Specify led_sub_arg as fault, power, att, or active. Specify mode_sub_arg as on, off or blink. Changing the state of the LED does not change the state of the receptacle or occupant. Normally, the LEDs are controlled by the hot plug controller, no user intervention is necessary. Use this command for testing purposes. Caution: Changing the state of the LED can misrepresent the state of occupant or receptacle. The following command prints the values of LEDs: example# cfgadm -x led pci0:hpc0_slot1 Ap_Id Led pci0:hpc0_slot1 power=on,fault=off,active=off,attn=off The following command turns on the Fault LED: example# cfgadm -x led=fault,mode=on pci0:hpc0_slot1 The following command turns off the Power LED: example# cfgadm -x led=power,mode=off pci0:hpc0_slot0 The following command sets the active LED to blink to indicate the location of the slot: example# cfgadm -x led=active,mode=on pci0:hpc0_slot3 EXAMPLES
Example 1: Printing out the Value of Each Slot The following command prints out the values of each slot: example# cfgadm -l Ap_Id Type Receptacle Occupant Condition c0 scsi-bus connected configured unknown c1 scsi-bus connected unconfigured unknown c2 scsi-bus connected unconfigured unknown cpci_slot1 stpci/fhs connected configured ok cpci_slot2 unknown empty unconfigured unknown cpci_slot4 stpci/fhs connected configured ok cpci_slot5 stpci/fhs connected configured ok Example 2: Replacing a Card The following command lists all DR-capable attachment points: example# cfgadm Type Receptacle Occupant Condition c0 scsi-bus connected configured unknown c1 scsi-bus connected unconfigured unknown c2 scsi-bus connected unconfigured unknown cpci_slot1 stpci/fhs connected configured ok cpci_slot2 unknown empty unconfigured unknown cpci_slot4 stpci/fhs connected configured ok cpci_slot5 stpci/fhs connected configured ok The following command unconfigures and electrically disconnects the card: example# cfgadm -c disconnect cpci_slot4 The change can be verified by entering the following command: example# cfgadm cpci_slot4 Ap_Id Type Receptacle Occupant Condition cpci_slot4 unknown disconnected unconfigured unknown Now the card can be swapped. The following command electrically connects and configures the card: example# cfgadm -c configure cpci_slot4 The change can be verifed by entering the following command: example# cfgadm cpci_slot4 Ap_Id Type Receptacle Occupant Condition cpci_slot4 stpcipci/fhs connected configured ok FILES
