5.6SCSI COMMAND DESCRIPTIONS

The SCSI command descriptions that follow this page contain detailed information about the SCSI commands that are supported by the drive. Each description provides a Data Format and Field Descriptions for the Command Descriptor Block for the described command.

The commands are presented in alphabetic order, and each command starts on a new, odd-numbered page.

Common Fields

Several fields that are common to many commands are described here, rather than being repeated throughout the descriptions. These fields include:

Reserved – Reserved bits, fields, bytes, and code values are set aside for future standardization and must be set to 0. If the drive receives a command that contains non-0 bits in a reserved field or a reserved code value, the command is terminated with a CHECK CONDITION status and the sense key set to ILLEGAL REQUEST. However, there are some fields that are not checked for compatibility with older SCSI initiators.

Control – The Link Bit and Flag Bit are supported.

RelAdr – Not supported; must be 0.
