Sense Data
D–10
0819 RTR Not Required. Receiver of Ready to Receive has nothing to send.
081A Request Sequence Error. Invalid sequence of requests.
081B Receiver in Transmit Mode. A race condition exists: a normal-flow request was
received while the half-duplex contention state was not-receive, (*S, ¬R), or
while resources (such as buffers) necessary for handling normal-flow data
were unavailable. (Contrast this sense code with X'2004', which signals a
protocol violation.)
081C Request Not Executable. The requested function cannot be executed because
of a permanent error condition in the receiver.
081D Invalid Station/SSCP ID. The station ID or SSCP ID in the request was found to
be invalid.
081E Session Reference Error. The request contained reference to a half-session
that either could not be found or was not in the expected state (generally
applies to network services requests).
081F Reserved.
0820 Control Vector Error. Invalid data for the control vector specified by the target
network address and key.
0821 Invalid Session Parameters. Session parameters were not valid or not
supported by the half-session whose activation was requested.
0822 Link Procedure Failure. A link-level procedure has failed due to link equipment
failure, loss of contact with a link station, or an invalid response to a LINK
command. (This is not a path error because the request being rejected was
delivered to its destination.)
0823 Unknown Control Vector. The control vector specified by a network address
and key is not known to the receiver.
0824 Logical Unit of Work Aborted. The current unit of work has been aborted;
when sync point protocols are in use, both sync point managers are to revert to
the previously committed sync point.
0825 Component Not Available. The LU component (a device indicated by an FM
header) is not available.
0826 FM function not supported. A function requested in an FMD RU is not
supported by the receiver.
0827 Intermittent Error — Retry Requested. An error at the receiver caused an RU
to be lost. The error is not permanent. Retry or the RU (or chain) is requested.
0828 Reply Not Allowed. A request requires a normal-flow reply, but the outbound
data flow for this half-session is quiesced or shut down. There is no delayed
reply capability.
