qlc1020 -- QLogic PCI IQ host adapter

Description

The QLogic PCI IQ host adapter subsystem enables SCSI target drivers (such as sd01 and st01) to communicate on the SCSI bus with target controllers and logical units. This driver implements the Portable Device Interface (PDI) for such PDI target drivers.

This driver supports Hot Insertion/Removal of devices on the SCSI Bus via the pdiadd(1M) and pdirm(1M) commands. It supports WIDE SCSI controllers.

You can access this subsystem directly using the pass-through driver interface. This allows you to issue sb control blocks directly to the target controller. To find the appropriate device to use, while any device is being accessed through the target driver (for example, sd01), use the B_GETDEV ioctl to get the major and minor numbers of the pass-through node. This node may be created and opened for pass-through use (SDI_SEND ioctl).

ioctl calls

All of the pass-through ioctl(2) commands documented on the sdi(7) manual page are supported by this driver. In addition, the following command is supported:

SDI_HBANAME
Returns the host bus adapter driver name.
