Adaptec AIC-6x60 family SCSI host adapter subsystem
The Adaptec AIC-6x60 family host adapter driver provides a Storage
Interface (SDI)-compliant interface to any Adaptec Host Adapters based on
the Adaptec AIC-6x60 family of SCSI controller chips.
These devices include AHA-1505, AHA-1510,
and AHA-1720A/1722A as well as any motherboard implementations
using the AIC-6260 or the AIC-6360 SCSI chips.
The Adaptec AIC-6x60 family 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.
Adaptec SCSI controllers cannot be used reliably with Emulex
SCSI/ESDI bridge controllers (also known as
This is due to hardware-induced timing differences between these bridge
controllers and any SCSI controllers other than the one that
they were designed to be used with.
It is not possible to provide a software solution to this problem.
Exercise extreme caution 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.
