IFI004
Explanation: HCPIFIIN was attempting to do one of
the following:
v Transfer control to the interrupt response address
specified in the IORBK field IORIRA, but it contained
zeros.
v Call the emergency error recovery procedure, but
was unable to resolve its address.
User Response:
v For the first case, check R10 to see that it is pointing
to a valid IORBK. If R10 contains the address of an
IORBK, the interrupt response address was probably
destroyed or never set when the request was
initiated. Also examine the status in IORBK.
v For the second case, verify that the emergency error
recovery procedure (HCPIEERP) was included in the
system.
IFI005
Explanation: (soft abend) The test subchannel
(TSCH) test function control bits (IRBFCTL) and activity
control bits (IRBACTL) are zeros, indicating no valid
status.
User Response: The XA architecture expects a
status. This is probably a hardware malfunction. Call
your IBM hardware representative to diagnose the
malfunction.
IFI006
Explanation: HCPIFI attempted to process an IORBK
with the IORXFLG.IROCPSUS bit on, but field
IORSUSND was zero.
User Response: Examine the IORBK, the RDEV, and
the CP trace table to determine what routine obtained
the IORBK. Verify that the routine that built the IORBK
correctly set both the IORSUSND field and the
IORCPSUS bit. If the routine did not, correct that
routine. If it did, attempt to determine how IORSUSND
was set to zero (or how IORCPSUS was set to one).
IFI007
Explanation: (Soft abend) Return code 4 has been
received from the error recover routine. This return code
is incorrect and should not occur.
User Response: This is probably a programming
error. Examine the CP trace table to analyze the events
relating to that subchannel which led to this incorrect
return code being issued.
IFI020
Explanation: Start subchannel (SSCH) simulation for
a Sense operation for a logical device resulted in one of
the following:
v A return code that was greater than 12 or not a
multiple of 4.
v A return code 8, which correlates to a SSCH
condition code 2. An I/O operation was attempted
while another one was in progress for the same
logical device.
User Response: Examine the CP trace table to
analyze other events relating to the logical device or
subchannel.
Look at the RDEV (pointed to by R8), which is used by
HCPIFI to manage the logical device. The RDEV field,
RDEVLSOP, points to the corresponding logical
subchannel.
Verify that the SSCH simulation module for logical
devices (HCPLCISS) is adhering to the interface defined
in the prologue.
IFI021
Explanation: Test subchannel (TSCH) simulation for a
logical device indicated one of the following:
v A return code that was greater than 12 or not a
multiple of 4.
v A return code 8, which correlates to a TSCH
condition code 2 which is undefined by the XA
architecture.
User Response: Look at the RDEV (pointed to by
R8), which is used by HCPIFI to manage the logical
device. The RDEV field RDEVLSOP points to the
corresponding logical subchannel.
Verify that the TSCH simulation module for logical
devices (HCPLCITS) is adhering to the interface defined
in the prologue.
IIO001
Explanation: The subchannel for the IPL device does
not exist or cannot be modified.
User Response: Verify that R8 contains the address
of the RDEV for the IPL device. Try moving the IPL
device to an address the system knows.
IIO002
IFI004 IIO002
Explanation: The IPL device cannot be brought
online.
User Response: R15 contains the address of the
error message describing the condition that prevented
the IPL device from being brought online. Refer to the
message description for the appropriate action.
