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.
