A request was made to start structure rebuild processing or to stop in progress structure rebuild processing for all structures in one or more coupling facilities, but the request was not successful for one or more of the structures in that coupling facility. Structure rebuild processing type can be either rebuild or duplexing rebuild. The request was either due to a SETXCF command or invocation of an IXLREBLD macro.

In the message text:

strname

The name of the structure.

cfname

The name of the coupling facility.

STARTED

The request was to start structure rebuild processing.

STOPPED

The request was to stop structure rebuild processing.

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.

REBUILD HAS ALREADY BEEN INITIATED FOR THE STRUCTURE

The structure rebuild process is already in progress for the structure. Use the DISPLAY XCF,STR command to determine the type (rebuild or duplexing rebuild0 and method (user-managed or system-managed) of the structure rebuild process.

REBUILD STOP HAS ALREADY BEEN INITIATED FOR THE STRUCTURE

Stop has already been initiated for the structure rebuild process.

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.

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 rebuild request would have resulted in a user-managed rebuild, but the structure has no active connectors to participate in rebuild.

REBUILD STOP IS IN PROGRESS FOR THE STRUCTURE

Rebuild stop is in progress for the structure.

STRUCTURE NOT IN REBUILD PROCESS

The structure is not in the rebuild process.

CLEANUP HAS BEGUN, REBUILD CANNOT BE STOPPED NOW

Rebuild has entered the cleanup phase. Rebuild cannot be stopped now.

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 facility has better connectivity than the current one. The rebuild, which was initiated because of 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 facility has better connectivity than the current one. The rebuild would cause a degradation in connectivity as determined by SFM system weights, if accepted.

Note: When this reason is received for an operator initiated rebuild by STRNAME or CFNAME and the installation needs to rebuild the structures, a SETXCF START,REBUILD command specifying LESSCONN=CONTINUE can be used to force the rebuild to continue despite this condition. Because this might cause active connections to the structure to lose connectivity to the structure, do not use LESSCONN=CONTINUE unless you understand the impact to the application or subsystem. Consult the application or subsystem documentation for recommendations.

XCF SIGNALLING STRUCTURES CANNOT BE REBUILT USING CFNAME KEYWORD

Due to the availability constraints of XCF Signalling Structures, these structures cannot be rebuilt using the CFNAME option. They must be rebuilt individually using the STRNAME option.

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.

TYPE OF STOP REQUEST DOES NOT MATCH TYPE OF REBUILD IN PROGRESS

SETXCF STOP,REBUILD or IXLREBLD REQUEST=STOP was issued to stop a duplexing rebuild OR SETXCF STOP,REBUILD,DUPLEX or IXLREBLD REQUEST=STOPDUPLEX was requested to stop a non-duplexing rebuild.

DUPLEXING NOT ESTABLISHED, CANNOT STOP TO KEEP NEW STRUCTURE

SETXCF STOP,REBUILD,DUPLEX,KEEP=NEW or IXLREBLD REQUEST=STOPDUPLEX KEEP=NEW was requested and the rebuild has not yet entered the duplex established phase. Stop requests to switch to the new structure are not accepted until the rebuild enters the duplex established phase.

ALREADY STOPPING IN THE OTHER DIRECTION

The request to stop a duplexing rebuild was not processed because duplex rebuild stop has already been initiated for this structure name in the other direction. Either KEEP=OLD was requested and KEEP=NEW type of duplex rebuild stop is in progress or KEEP=NEW was requested and KEEP=OLD type of duplex rebuild stop is in progress.

STRUCTURE HAS FAILED

The rebuild start request was rejected for one of the following reasons:

• 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.
• The rebuild start request would result in a system-managed rebuild. System-managed rebuild is not allowed when the structure is in the failed state.

NO OTHER COUPLING FACILITY FOUND IN PREFERENCE LIST

On a rebuild start request, either LOCATION=OTHER was specified or defaulted to for a request to start a duplexing rebuild. In addition to avoiding the 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.
• The structure already exists in the only suitable coupling facility. The same coupling facility can only be selected as the target for the system-managed process if a CFRM policy change is pending for the structure and one of the following is true:
  • The policy change does not affect the SIZE or the INITSIZE parameters.
  • The policy change affects the SIZE or the INITSIZE parameter and all of the structure connectors specified IXLCONN ALLOWALTER=YES.
• A potentially suitable coupling facility does not permit structure allocation.

START REASON INAPPROPRIATE FOR SYSTEM-MANAGED PROCESS

An IXLREBLD REQUEST=START invocation would have resulted in system-managed processing (for example, rebuild). The request specified a STARTREASON of LOSSCONN or STRFAILURE, which are not valid reasons for the requested process.

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 to the coupling facility containing the target structure.

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.
