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:
