Field Definition
Peripheral qualifier The peripheral qualifier is used with the peripheral device type field to
identify the device currently connected to the logical unit. The peripheral
qualifier field may take on the following values:
000b = The specified peripheral device type is currently
connected to this logical unit. This peripheral qualifier does not
mean that the device is ready for access by the initiator.
001b = The FibreBridge is capable of supporting the specified
peripheral device type on this logical unit. However, the physical
device is not currently connected to this logical unit.
011b = The FibreBridge is not capable of supporting a physical
device on this logical unit. For this peripheral qualifier, the
peripheral device type will be set to 1Fh.
Peripheral device
type
The peripheral device type field indicates the type of peripheral on this
logical unit.
03h = Processor type device. The FibreBridge responds as a
processor type device.
1Fh = Unknown or no device type.
ISO version The FibreBridge does not claim compliance with the ISO version of
SCSI. This field will be set to 00b.
ECMA version The FibreBridge does not claim compliance with the ECMA version of
SCSI. This field will be set to 00b.
ANSI version The ANSI version field will be set to 3h indicating compliance with ANSI
X3.301-1997.
AERC The Asynchronous event reporting capability field will be set to 0b.
NACA The Normal ACA Supported bit will be set to 0b.
HiSup The Hierarchical support bit indicates if the FibreBridge is configured to
implement Hierarchical LUN addressing. See the section on LUN
Address Methods for additional information.
Additional length The additional length field specifies the length in bytes of the
parameters. If the allocation length of the command descriptor block is
too small to transfer all of the parameters, the additional length is not be
adjusted to reflect the truncation.
TCQ The TCQ field will be set to 1b to indicate support for command queuing.
Vendor identification The Vendor identification field is set to ‘ATTO’ and padded with spaces.
Product identification The Product identification field is set to ‘FibreBridge xxxx’, where xxxx is
the four-digit ATTO model number of the specific FibreBridge.
Product revision level The product revision level field is set to the current firmware revision
level. The revision consists of four ASCII characters.
