Patent ID: 7721007

Claim:
A method for transmitting a non-SCSI (non-Small Computer System Interface) read command via SCSI commands, comprising steps of providing a first CDB (Command Descriptor Block) for a Write Buffer command, said first CDB including context information, byte_ 0 , of said first CDB is an opcode for said Write Buffer command; embedding a non-SCSI read command in Writer Buffer Data of said Write Buffer command, byte 1 of said first CDB is an opcode for said non-SCSI read command; providing a second CDB for a Read Buffer command, said second CDB including said context information, byte_ 0 , of said second CDB is an opcode for said Read Buffer command and byte_ 1 , of said second CDB is an opcode for said non-SCSI read command; and embedding data associated with said non-SCSI read command in Read Buffer Data of said Read Buffer command, wherein said context information comprises an identifier unique to said first CDB and is used to correlate said first CDB and said second CDB to complete transmission of said non-SCSI read command.
