qlc1020 -- QLogic PCI SCSI host adapter

Description

The QLogic PCI SCSI host adapter subsystem enables SCSI target drivers (such as sd01(7) and st01(7)) to communicate on the SCSI bus with target controllers and logical units. This driver implements the Storage Device Interface (SDI) for such SDI target drivers.

This driver supports hot insertion and removal of devices on the SCSI Bus via the sdiadd(1M) and sdirm(1M) commands. It supports WIDE SCSI controllers.

It is also possible for an application to access the SCSI bus subsystem directly by using the pass-through interface. See pt_open(3X).

ioctl calls

The following command is supported:

SDI_HBANAME: Returns the host bus adapter driver name.

Notices

Extreme caution should be exercised when using the pass-through interface. It is possible to interfere with normal system I/O and cause hangs if pass-through is used to an active device. Pass-through should only be used to a device that is otherwise quiescent.
