BusLogic FlashPoint SCSI host adapter subsystem
The BusLogic FlashPoint SCSI host adapter driver provides a Storage Device
Interface (SDI) compliant interface to BusLogic FlashPoint SCSI Host Adapters.
The supported devices include the BT-930, BT-932, BT-950,
and the BT-952.
The BusLogic SCSI host adapter driver enables SDI-compliant target drivers
(such as sd01 and st01) to communicate on the SCSI bus with target
controllers and logical units. This allows normal access to mass-storage
devices using standard system interfaces and filesystems.
It is also possible for an application to access the SCSI bus
subsystem directly by using the pass-through interface.
BusLogic SCSI adapters support the Tag Command Queueing feature as default.
To disable this feature, change the value of the flashpt_do_tag variable in
the /etc/conf/pack.d/flashpt/space.c file from 1 to 0. After you have changed
the value in the file, rebuild the kernel for the Tag Command Queueing feature
to be effective.
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.
