Provides access to the SCSI adapter driver.
The scsi special file provides an interface to an attached SCSI adapter. This special file should not be opened directly by application programs (with the exception of diagnostics applications). The /dev/scsi0, /dev/scsi1, ... /dev/scsin files are the scsi special files.
The description of the SCSI Adapter device driver in AIX® Version 7.1 Technical Reference: Kernel and Subsystems, Volume 1 provides the implementation specifics for the SCSI adapter.
