DUPLEXING REBUILD OF STRUCTURE
strname WAS
NOT
{INITIATED|STOPPED}
BY MVS. REASON:
reasonExplanation
An event occurred that triggers the
system to take action to start or stop a duplexing rebuild for the
structure. Action was not taken due to the provided reason. This may
mean that the environmental conditions required for a duplexing rebuild
have not all been met, and may not necessarily require urgent action.
In
the message text:
- strname
- The name of the structure
- action
- The word INITIATED or STOPPED
- reason
- One of the following:
- STRUCTURE NOT DEFINED IN THE CFRM ACTIVE POLICY
- The structure is not defined in the CFRM active policy and therefore
is not allocated in any coupling facility.
- STRUCTURE NOT ALLOCATED
- The structure is not allocated in any coupling facility.
- AT LEAST ONE ACTIVE CONNECTION INDICATED THAT REBUILD IS NOT ALLOWED
- Rebuild not permitted because IXLCONN with ALLOWREBLD=NO was specified
by at least one active connection.
- DEFERRED UNTIL PROCESS COMPLETION
- A duplexing rebuild could have been initiated or stopped, but
the action is instead deferred. The action is deferred to prevent
duplexing rebuild processing from interfering with other potentially
more important processing. If necessary, the system will attempt to
take action once none of the following processing is in progress:
REBUILD (other than the duplex established), REALLOCATE, POPULATECF,
and LOSSCONN RECOVERY. The DISPLAY,SCF,STRUCTURE,STATUS=(RBPROC,RPEND,LOSSCONN)
can be used to display structures associated with processing that
is causing the deferral.
- COUPLE DATA SET FOR CFRM NOT AVAILABLE
- The couple data set for CFRM is not available to this system.
- NO ACTIVE CONNECTIONS TO THE STRUCTURE
- The structure has no connectors to participate in rebuild.
- REBUILD STOP IS IN PROGRESS FOR THE STRUCTURE
- Rebuild stop is in progress for the structure.
- XES FUNCTION NOT AVAILABLE
- XES functions are not available. This can be because the hardware
necessary to provide XES functions is not present.
- AN UNEXPECTED ERROR OCCURRED
- An unexpected error occurred during rebuild processing.
- NO ELIGIBLE STRUCTURES FOUND IN COUPLING FACILITY
- On a rebuild start request, no structures eligible for rebuild
were found in the coupling facility specified. On a rebuild stop
request, no structures eligible for rebuild stop were found in the
coupling facility specified.
- COUPLING FACILITY NOT DEFINED IN THE CFRM ACTIVE POLICY
- The coupling facility is not defined in the CFRM active policy.
- 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. The system evaluated the set of active connections that
lost connectivity to the current structure as compared with the set
of active connections that would not be able to connect to the rebuild
new structure. The system terminates structure rebuild processing
because the result of the rebuild would cause additional active connections
to lose connectivity.
- NO COUPLING FACILITY PROVIDED BETTER OR EQUIVALENT CONNECTIVITY
- No other coupling facility has better connectivity than the current
one. The rebuild would cause a degradation in connectivity as determined
by SFM system weights, if accepted.
- DUPLEXING REBUILD NOT ALLOWED FOR THE STRUCTURE
- The structure does not support duplexing rebuild
for one of the following reasons:
- DUPLEX(DISABLED) was specified or defaulted to in the CFRM active
policy for the structure.
- There are failed persistent connections that are unavailable until
a larger CFRM couple data set is made available.
- A user-managed duplexing rebuild could not be started
because:
- User-managed duplexing rebuilds are not supported for the structure
type.
- At least one active or failed-persistent connection specified
or defaulted to IXLCONN ALLOWDUPREBLD=NO.
- A system-managed duplexing rebuild could not be started
because:
- The structure has at least one active connector, and none of the
connectors (active or failed-persistent) specified IXLCONN ALLOWAUTO=YES
when connecting.
- A system-managed duplexing rebuild is not supported when a CFRM
policy change is pending for the structure.
- STRUCTURE HAS FAILED
- The request was to start a duplexing rebuild and
the structure has failed. Duplexing rebuild is not allowed when the
structure is in the failed state.
- NO OTHER COUPLING FACILITY FOUND IN PREFERENCE LIST
- SETXCF START,REBUILD was requested and LOCATION=OTHER was either
specified on the rebuild request or defaulted to for STARTREASON=LOSSCONN
or for a request to start a duplexing rebuild. In addition to avoiding
the coupling facility in which the structure is currently allocated,
when a duplexing rebuild is stopped by the operator and DUPLEX(ENABLED)
is specified in the active policy, the subsequent duplexing request
initiated due to DUPLEX(ENABLED) will avoid the coupling facility
in which the previous instance of the structure was allocated when
the duplexing rebuild was stopped.
- STRUCTURE DOES NOT SUPPORT SYSTEM-MANAGED PROCESSES
- The structure does not support system-managed processes (for example,
rebuild) for one of the following reasons:
- The structure was not allocated in a coupling facility at or above
the minimum CFLEVEL required for the current process by a system
supporting system-managed processing.
- The structure has connections that have not been reconciled into
the CFRM active policy.
- Structure cleanup is in progress for the structure.
- CONNECTORS DO NOT SUPPORT SYSTEM-MANAGED PROCESSES
- The requested system-managed process cannot be initiated for one
of the following reasons:
- The structure has at least one active connector and at least one
of the connectors (active or failed-persistent) did not specify IXLCONN
ALLOWAUTO=YES when connecting.
- A duplexing rebuild cannot be initiated for a structure that has
only failed-persistent connectors, and at least one of the failed-persistent
connectors did not specify IXLCONN ALLOWAUTO=YES when connecting.
- NO SUITABLE COUPLING FACILITY IN PREFERENCE LIST
- The requested system-managed process cannot be initiated
for one or more of the following reasons:
- The preference list is empty.
- The preference list contains no other coupling facility at or
above the minimum CFLEVEL required for the current process.
- A potentially suitable coupling facility does not
permit structure allocation.
- AT LEAST ONE CONNECTOR HAS LOST CONNECTIVITY TO THE STRUCTURE
- The requested system-managed process (for example, rebuild) cannot
be initiated because one or more of the connectors to the target
structure has lost connectivity.
- CFRM COUPLE DATA SET DOES NOT SUPPORT SYSTEM-MANAGED PROCESS
- The CFRM couple data set does not support the requested system-managed
process (for example, rebuild), because the CFRM couple data set
was not formatted at or above the minimum version for the system-managed
process requested. Use the DISPLAY XCF,COUPLE,TYPE=CFRM command
to determine the format of the CFRM couple data set. To support system-managed
rebuild the CFRM couple data set should be formatted specifying “ITEM
NAME(SMREBLD) NUMBER(1)”. For system-managed duplexing rebuild,
“ITEM NAME(SMDUPLEX) NUMBER(1)” should also be specified when formatting
a CFRM couple data set. Specifying “ITEM NAME(SMDUPLEX) NUMBER(1)”
implicitly formats a CFRM couple data set that supports both system-managed
rebuild and system-managed duplexing rebuild.
- STRUCTURE WITH NO CONNECTORS HAS NEVER BEEN SYSTEM-MANAGED DUPLEXED
- A system-managed duplexing rebuild cannot be initiated because
there are no connections to the structure and the structure has not
previously been duplexed using system-managed processing.
- ALLOCATION OF REBUILD NEW STRUCTURE FOR DUPLEXING REBUILD NOT
FEASIBLE
- Allocation of the rebuild new structure instance in support of
a duplexing rebuild is not feasible. Message IXC574I will contain
additional diagnostic information.
- STRUCTURE OBJECTS IN STORAGE-CLASS MEMORY
- The duplexing rebuild could not be started because storage-class
memory is in use.
