5.8 SCSI 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.
