Bus condition
Asynchronous conditions used to change the transition of the SCSI bus state. The
ATTENTION and RESET conditions are used.
Bus phase
Name of the SCSI bus state. The SCSI bus can be either in the BUS FREE,
ARBITRATION, SELECTION, RESELECTION, or INFORMATION
TRANSFER phase. The INFORMATION TRANSFER phase is further
subdivided into the DATA IN, DATA OUT, COMMAND, STATUS, MESSAGE
IN, or MESSAGE OUT phase depending on the type of transferred information.
Command
Instruction for input/output operation issued to the target. This manual uses CDB
for short.
Common Command Set (CCS)
Standard SCSI logical specification, which has been defined by the relevant
working group of the American National Standards Institute (ANSI). This
specification covers the functions that must be implemented in direct access
storage devices (DASDs), such as hard disk drives.
Common Descriptor Block (CDB)
Data structure that contains an input/output SCSI command. A CDB is sent from
the initiator to the target.
Disconnect
Operation executed by the target to temporarily disconnect the connection between
the SCSI bus and the initiator when use of the SCSI bus is no longer required
while the target is executing a command.
Initiator (INIT)
SCSI device that starts input/output operations on a SCSI bus. This manual also
uses INIT for short.
