HiSup:
A hierarchical support (HISUP) bit set to zero indicates the SCSI target device does not use the
hierarchical addressing model to assign LUNs to logical units
Response Data Format:
This Standard Inquiry Data is in SCSI-2 format. Set to 2.
Additional Length:
The media changer uses this field to indicate the number of additional bytes of INQUIRY response
data available.
SCCS:
The media changer does not contain an embedded storage array controller component. Set to 0.
ACC: The ACC bit set to zero indicates that no access controls coordinator may be addressed through
this logical unit.
TPGS:
The media changer does not support asymmetric logical unit access or supports a form of
asymmetric access that is vendor specific. Neither the REPORT TARGET GROUPS nor the SET
TARGET GROUPS commands is supported.
3PC: A Third-Party Copy (3PC) bit set to zero indicates that the media changer does not supports
third-party copy commands such as the EXTENDED COPY command.
Protect:
A PROTECT bit set to zero indicates that the media changer does not support protection
information.
BQue: Basic Queuing is not supported, set to 0.
EncServ:
An Enclosure Services (ENCSERV) bit set to zero indicates that the media changer does not
contain an embedded enclosure services component.
MultiP:
A MULTIP bit set to zero indicates that this SCSI target device has a single port and does not
implement the multi-port requirements.
MChanger:
This medium changer is not an attached medium changer. Set to 0.
Addr16:
When Addr16 is set to 1, the media changer does support 16-bit wide SCSI addresses. When set
to 0, indicates that the media changer does not support 16-bit wide SCSI addresses.
WBus16:
When WBus16 is set to 1, the media changer transfers SCSI data over an 16-bit wide bus. When
WBus16 is not set data transfers are done over an 8-bit wide bus.
Sync: When Sync is set to 1, data transfers are done in synchronous mode. When Sync is not set, data
transfers are done in asynchronous mode.
Linked:
Linked Commands are not supported. Set to 0.
CmdQue (Command Queuing):
For Fibre Channel, this is returned as 1, indicating command queuing is supported. For SCSI, this
is returned as 0, indicating no command queuing is supported.
