Target/Adapter ID field is equal to FFH ( indicat ing a Board -cont rol
command).
In a Pass-through Parameter Block: An invalid tag type was

specified.
In a Message Pass-through Parameter Block: A non-

02H Bad Unit Number
This code will be re ported for the followi ng conditions:
Target/Adapter ID field: The value specified in the Target/
Adapter ID field of a Parameter Block was not valid (valid values
are 00H-0FH and FFH).
In a Pass-through Parameter Block: The value s pecifie d in the
Target ID field is the same as the SCSI ID assigned to the RF3880.
This is not a valid S CSI ID to issue comm ands to.
In a Pass-through Parameter Block: the value used in the L UN
field of the SCSI command contained in the Parameter Block is
invalid. (Valid values are 00H-07H.)
In General Options Parameter Block: the value specified in
the SCSI Bus ID field (used to designate an RF3880 SCSI ID othe r
than that set with jum pers) is invalid. (Valid values are 00H-0FH.)
In Unit Options or Extended Unit Options Parameter
Block: Value specified in the Unit SCSI ID field was inv alid. (Valid
values are any number between and including 00H and 0FH, not
being used by the RF3880.)
0FH Bad Command List
Size
This code will be re ported when the Start Command List
command terminates for th e fo ll owing reasons:
- Number of Parameter Blocks field contains invalid value. (Valid
values are 2-2034.)
- Number of Status Blocks field contains i nvalid value. (V alid valu es
are 2 -4096.)
*10H Bad Command List
Index
This code is returned under these conditions:
- Parameter Block In (PBIN) index exceeded the number of
Parameter Blocks that can be in th e li st .
- Status Block Out (SBOUT) index exceeded the number of Status
Blocks that can be in the list.
- A VME bus error occurred while accessing the Status Block list.
*11H State wrong for Start/
Stop Command List
command
This code is returned under these conditions:
Start Command List command issued when a com mand list is
already active.
Stop Command List command issued when no command list is
presently active.
Command List Channel Attention issued when no Command
List is active.
*14H General Firmware
Timeout
The adapter times each of its transfers; it will report this error if a
VMEbus transfer takes too long to complete. On the VMEbus, this
error can occur for tran sfers of parameters as well as transfers of data .
*15H VMEbus Error
Occurred A VMEbus error was detected while the adapter was transferring
either parameters or data.
1DH SCSI General TimeoutFor Pass-through operations, this error will be reported if a SCSI
operation takes too long to complete.
1EH SCSI Select Timeout
For Pass-through operations, this code is reported when no SCSI
device responds to the select ion s equenc e wit hin the timeou t per iod.
The timeout period is specified in the Uni t Options command or
Extended Unit Options comm a n d.
1FH SCSI Disconnect
Timeout
For Pass-through commands, this code is reported when a
disconnected SCSI device does not reselect the adapter within the
timeout period. The time out period is specified in t he Unit Options
command or Extended Unit Options command.
20H SCSI Parity Error For Pass-through operations, this code is reported for any SCSI
information transfer (m essage, command, data or status) that results
in a parity error
