wd7000 -- 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.
