Table C-2. MSR Result Code Definitions
Code
Hex Meaning
0 00h Success - Result codes are included in responses to MSI
*
commands
upon completion, and with the Cartridge Load Complete Interrupt. If the
result code is other than Success, the command failed to complete its
execution properly (see also EOR
*
Encountered and Completed,
below). Certain responses to information requests may return Success
even if transport information is not available - see the appropriate
message description.
1 01h Command Aborted -Command completion was via its abortion by an
MSI Abort command.
2 02h Nothing to Abort - An Abort command was received from the MSI, but
there are no outstanding commands to abort. This may occur, for
instance, if the response to a command is being sent when the Abort
command arrives, or if the MSR entered the suspended state with no
remaining queued commands.
3 03h MSI Handshaking Fault - An error was detected in handshaking
signals/timing on the MSI/MSR Physical Block interface during a Write,
Read or Loop Physical Block command.
4 04h MSI Command Out Of Logical Sequence - A command was received
from the MSI which cannot be executed at this time.
5 05h Operation Time-out - An MSR operation has taken longer than the
established maximum time to complete, indicating an MSR internal
problem.
6 06h Data Path Fault - An error has been detected in the read or write data
path hardware which prevents successfully processing a Physical
Block; e.g., a parity error.
7 07h Unsupported Cartridge - The transport has detected a cartridge tab
configuration which is not supported by the MSR, therefore no tape
motion operations are executable.
8 08h Uncorrectable Data Error - A Read/Loop Physical Block command has
failed due to an incorrect Physical Block checksum.
9 09h Write Protected - An attempt was made to write or format tape in a
cartridge which the transport has determined is write protected.
10 0Ah No Cartridge - An attempt was made to perform a tape motion or
cartridge operation, but the transport detects that no cartridge is
loaded.
11 0Bh Read After Write Fault - Write mode maximum error criteria have been
exceeded and the maximum number of rewrites allowed, if any, has
been exhausted.
