The document outlines 13 test cases for different SCSI commands with transfer lengths and directions. It also describes preliminary procedures for initializing a device including inquiry, test unit ready, and capacity commands. Failure procedures are specified for read/write commands returning illegal request sense keys and for test unit ready commands returning a stall.
