Explanation
Rebuild processing for a XES List Structure used
by the XCF signalling service has completed. As indicated by result,
the structure may have been rebuilt or rebuild processing may have
been stopped.
In the message text:
- strname
- The name of the XES structure defined to XCF for signalling.
- result
- Indicates how rebuild processing completed. The result can
be:
- SUCCESSFUL
- The structure was rebuilt.
- STOPPED
- Rebuild processing was stopped. The structure was not rebuilt.
- rebuildrsn
- Indicates why processing of a structure rebuild request was initiated
on this system:
- OPERATOR REQUEST
- The operator entered a SETXCF START,REBUILD command for this structure.
- LOST CONNECTIVITY TO FACILITY
- This system lost connectivity to the coupling facility containing
the structure.
- STRUCTURE FAILURE
- This system detected a structure failure.
- MORE LISTS NEEDED
- This system determined that the structure was not allocated with
enough lists for all the signalling list paths that are needed.
- MORE SPACE NEEDED
- This system determined that more space was needed in the structure.
- UNABLE TO START LIST MONITORING
- This system was unable to establish list monitoring for lists
used by XCF to manage the structure. The system initiated rebuild
processing in an attempt to connect to a new instance of the structure
in hopes that the necessary list monitoring could be established.
- IXLVECTR TOKEN NOT VALID
- The vector token used by this system when invoking the Local Vector
Service (macro IXLVECTR) is no longer valid. A structure failure may
cause a vector token to become invalidated. The system initiated rebuild
processing in an attempt to connect to a new instance of the structure.
A new vector token is assigned for the new structure.
- MORE SYSTEMS EXPECTED
- The system initiated rebuild processing to allocate the list structure
with more lists for signalling paths that new systems entering the
sysplex are expected to need in order to establish full signalling
connectivity. New systems are expected to enter the sysplex when the
primary sysplex couple data set is replaced by a couple data set formatted
with a larger MAXSYSTEM specification.
- PARTICIPANT, RSN=STRUCTURE FAILURE
- This system is participating in a rebuild of the structure initiated
by some other connector due to a structure failure.
- PARTICIPANT, RSN=OPERATOR REQUEST
- This system is participating in a rebuild of the structure initiated
by the operator.
- PARTICIPANT, RSN=MORE LISTS NEEDED
- This system is participating in a rebuild of the structure initiated
by some other connector due to a need for more lists.
- PARTICIPANT, RSN=MORE SPACE NEEDED
- This system is participating in a rebuild of the structure initiated
by some other connector due to a need for more space in the structure.
- PARTICIPANT, RSN=UNABLE TO START LIST MONITORING
- This system is participating in a rebuild of the structure initiated
by some other connector that was unable to start list monitoring.
- PARTICIPANT, RSN=IXLVECTR TOKEN NOT VALID
- This system is participating in a rebuild of the structure initiated
by some other connector since the vector token that the connector
used when invoking the Local Vector Service (macro IXLVECTR) is no
longer valid.
- PARTICIPANT, RSN=MORE SYSTEMS EXPECTED
- This system is participating in a rebuild of the structure initiated
by some other connector to allocate the list structure with more lists
for signalling paths that new systems entering the sysplex are expected
to need in order to establish full signalling connectivity. New systems
are expected to enter the sysplex when the primary sysplex couple
data set is replaced by a couple data set formatted with a larger
MAXSYSTEM specification.
- PARTICIPANT, RSN=DIAG080: n n
- This system is participating in a rebuild of the structure initiated
by some other connector for a reason that this system could not interpret.
- WHY STOPPED:
- Indicates that the structure rebuild was stopped. Applicable only
when result is STOPPED.
- stoppedrsn
- Indicates why processing of a structure rebuild request was stopped
on this system. Applicable only when result is
STOPPED.
- OPERATOR REQUEST
- The operator entered a SETXCF STOP,REBUILD command.
- LOST CONNECTIVITY TO NEW STRUCTURE
- This system lost connectivity to the coupling facility that contains
the rebuilt structure.
- LOST CONNECTIVITY TO OLD STRUCTURE
- This system lost connectivity to the coupling facility that contains
the original structure. The rebuild could not continue without access
to the original structure.
- FAILURE OF NEW STRUCTURE
- The rebuilt structure failed.
- FAILURE OF OLD STRUCTURE
- The original structure failed. The rebuild could not continue
without access to the original structure.
- NO COUPLING FACILITY PROVIDED BETTER CONNECTIVITY
- No other coupling facility has better connectivity than the current
one. The rebuild, which was initiated due to a loss of connectivity,
would cause a further degradation in connectivity if accepted.
- NO COUPLING FACILITY PROVIDED EQUIVALENT OR BETTER CONNECTIVITY
- No other coupling facility has equivalent or better connectivity
than the current one. The rebuild would cause a degradation in connectivity
as determined by SFM system weights, if accepted.
- WOULD LOSE SIGNAL CONNECTIVITY
- This system would lose signalling connectivity if it were to use
the rebuilt structure. The rebuild is stopped so the system can revert
to using the original structure for signalling.
- WOULD LOSE LISTS
- The rebuilt structure would not provide more lists than the original
structure, but the purpose of the rebuild was to increase the number
of lists in the structure.
- WOULD LOSE SPACE
- The rebuilt structure would not provide more space than the original
structure, but the purpose of the rebuild was to increase the amount
of space available within the structure.
- NO SUCCESSFUL CONNECTIONS TO NEW STRUCTURE
- None of the connectors were able to successfully connect to a
new instance of the structure.
- UNUSABLE, NEED ORIGINAL FOR CONNECTIVITY
- Other systems can use the rebuilt structure, but this system cannot.
The rebuild is stopped since this system would lose signalling connectivity
to some other system in the sysplex without the original structure.
- PARTICIPANT, RSN=LOST CONNECTIVITY TO NEW STRUCTURE
- This system is participating in a stop rebuild request that it
did not initiate. Some connector lost connectivity to the coupling
facility containing the rebuilt structure.
- PARTICIPANT, RSN=LOST CONNECTIVITY TO OLD STRUCTURE
- This system is participating in a stop rebuild request that it
did not initiate. Some connector lost connectivity to the coupling
facility containing the original structure and was unable to continue
rebuild processing.
- PARTICIPANT, RSN=FAILURE OF NEW STRUCTURE
- This system is participating in a stop rebuild request that it
did not initiate. Some connector detected that the new structure failed.
- PARTICIPANT, RSN=FAILURE OF OLD STRUCTURE
- This system is participating in a stop rebuild request that it
did not initiate. Some connector detected that the original structure
failed and was unable to continue rebuild processing.
- PARTICIPANT, RSN=WOULD LOSE SIGNAL CONNECTIVITY
- This system is participating in a stop rebuild request that it
did not initiate. Some connector determined that it would lose signalling
connectivity by using the rebuilt structure. The rebuild was stopped
to revert to signalling through the original structure.
- PARTICIPANT, RSN=WOULD LOSE LISTS
- This system is participating in a stop rebuild request that it
did not initiate. Some connector determined that the rebuilt structure
would not provide more lists than the original structure. The rebuild
was stopped since this was not acceptable.
- PARTICIPANT, RSN=WOULD LOSE SPACE
- This system is participating in a stop rebuild request that it
did not initiate. Some connector determined that the rebuilt structure
would not provide more space than the original structure. The rebuild
was stopped since this was not acceptable.
- PARTICIPANT, RSN=NO SUCCESSFUL CONNECTIONS TO NEW STRUCTURE
- This system is participating in a stop rebuild request that it
did not initiate. Some connector determined that no connector was
able to successfully connect to the rebuilt structure. The rebuild
is stopped since the structure could not be used for signalling.
- PARTICIPANT, RSN=UNUSABLE, NEED ORIGINAL FOR CONNECTIVITY
- This system is participating in a stop rebuild request that it
did not initiate. Some connector determined that it cannot use the
rebuilt structure, and that it would lose signalling connectivity
without the original structure.
- PARTICIPANT, RSN=DIAG081: n n
- This system is participating in a stop rebuild request that it
did not initiate. Some connector determined that it cannot use the
rebuilt structure. This system could not interpret the reason for
stopping the rebuild.
- PARTICIPANT, RSN=THE SPECIFIED POPULATECF IS LESS SUITABLE
- This system is participating in a stop rebuild request that it
did not initiate. POPULATECF rebuild processing determined that the
current coupling facility is a more suitable location for the structure
than the specified POPULATECF.
System action
If the structure is not usable by this system,
stop path processing is initiated. Otherwise the system continues
to use the structure for signalling.
Operator response
No response needed if the structure was rebuilt
as desired. If the structure was not rebuilt, resolve the problems
that caused rebuild processing to be stopped.
If the rebuild
was stopped because signalling connectivity would be lost, enter SETXCF
START path command(s) to start the additional signalling paths needed
to maintain signalling connectivity.
If the rebuild was stopped
because of a lack of connectivity to the coupling facility containing
an instance of the structure, restore physical connectivity to the
facility. Enter a CONFIG CHP command to configure channel paths to
the coupling facility, if needed. Enter a VARY PATH command to vary
the channel paths online to the system, if needed.
System programmer response
Ensure that coupling facilities are
correctly defined, configured, and operational. Ensure that the structure
is correctly defined in the CFRM active policy. Ensure that there
is sufficient space available in at least one coupling facility so
that a new instance of the structure can be allocated during rebuild
processing. Provide redundant signalling paths so that signalling
connectivity will be maintained even without this structure.
