v1_bustype_info_t(9s)
NAME
  v1_bustype_info_t - General: Stores bus information for the DEVGETINFO
  ioctl command

SYNOPSIS
       typedef struct v1_bustype_info {
	   int adpt_num;
	   int nexus_num;
	   int bus_num;
	   int ctlr_num;
	   int rctlr_num;
	   int slave_num;
	   int unit_num;
	   int pad0;
	   union {
	       v1_scsi_bus_info_t scsi;
	       uchar_t busdata[DEV_BUS_LEN];
	   } bus;
       } v1_bustype_info_t;

MEMBERS
  adpt_num
      Specifies the controller chip relative to the current adapter.  For
      example, if an adapter has two controller chips, chip A is instance 0
      and chip B is instance 1.

  nexus_num
      Specifies the slot that the adapter is using.

  bus_num
      Specifies the logical bus number	the adapter is plugged into.

  ctlr_num
      Specifies the systemwide instance number of the current adapter.	For
      example, two adapters with two controller chips result in instances 0,
      1, 2, and 3, corresponding to adapter 0, chip A; adapter 0, chip B;
      adapter 1 chip A; adapter 1, chip B.

  rctlr_num
      Specifies the remote ID for the adapter, usually 0.

  slave_num
      Specifies the number of the device relative to the controlling
      hardware. For example, if two disk devices are connected to chip A, one
      is slave 0 and the other is slave 1.

  unit_num
      Specifies the systemwide number of this device.

  bus Specifies a union of architecture-specific bus information, either a
      scsi_bus_info_t structure or an array of characters.






DESCRIPTION
  The v1_bustype_info_t data structure contains information about the bus
  type that is returned by the DEVGETINFO ioctl command.
