SCSI Host Bus Adapter Drivers

This chapter contains information on creating SCSI host bus adapter (HBA) drivers. The chapter provides sample code illustrating the structure of a typical HBA driver. The sample code shows the use of the HBA driver interfaces that are provided by the Sun Common SCSI Architecture (SCSA). This chapter provides information on the following subjects:

• Introduction to Host Bus Adapter Drivers

• SCSI Interface

• SCSA HBA Interfaces

• HBA Driver Dependency and Configuration Issues

• Entry Points for SCSA HBA Drivers

• SCSI HBA Driver Specific Issues

• Support for Queuing
