HCC
Event 4 PORT PROCESSOR (PP) SPECIFICATION EXCEPTION
Description: HCC has received a state-item from a host channel port. If the stateitem
was due to an NMS DOWN command, the port is freed and the facility is marked
as down. If the state-item was due to a software or hardware error, an attempt is
made to restart the port.
R8: Current instruction offset in HCC
R9: TSID
R10: Port output chain address
R11: Port input chain address
R12: Op-code of instruction that errored: bits 15-8
Type of error: bits 7-5
R13:
Subtype of error: bits 4-0
Supplementary status
R14: PPID
R15: Input flags from AGSYSRTN
Telcon generates this CENLOG.
NTRLPH
Description: This event occurs whenever the PP hardware or the PP program
detects a fatal hardware or software error. The line is brought down after occurrence
of this event. If the error type and subtype (logged registers R9 & R10) do not indicate
a hardware error, this information should be the basis for submission of a UCF. Other
information logged:
R9: Error type code
R10: Error sub-type code
R12: Output chain execution address
R13: Input chain execution address
R14: PP-D. Values in other registers may be useful for debug. The PP state-item
buffer is logged in the first 64 (X'40') words. The LCB and SCT (site control
table) are logged in the remaining words of the log entry.
Telcon generates this CENLOG.
RMLPH
Description: Port hung; Unable to force state-item by clearing the ‘C’ bit; but, the
state-item was never received. This is a hardware or microcode problem.
R15: Port number
