A.2.2 Supporting SCSI-Specific Functionality

Depending on the nature of its device, an SFD also might (or must) be responsible for the following SCSI-specific functionality:

In general, an SFD has the same responsibilities as a SCSI class driver for those requests that require device-specific handling. For a discussion of the functionality required of SCSI class drivers, see Section A.1.

The following subsections describe how SFDs provide this SCSI-specific functionality in the context of each standard routine that a SCSI filter driver commonly has.
