WD7000 FASST2 host adapter subsystem
Description
The WD7000 FASST2 SCSI 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 Storage Device Interface (SDI)
for such SDI target drivers.
It is also possible to 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-though 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 commands are supported:
- B_REDT
-
Reads the extended Equipped Device Table (EDT)
data structure that is stored in
the SCSI driver's internal data structure.
- B_HA_CNT
-
Gets the value of the number of host adapters for which the SCSI
driver is configured.
