IXC546I
REALLOCATE PROCESSING FOR STRUCTURE strname COULD NOT COMPLETE. THE REQUIRED strrbldtype WAS NOT STARTED BECAUSE reason

Explanation

A SETXCF START,REALLOCATE operator command was issued to start the REALLOCATE process. The named structure was the target of the REALLOCATE process but a relocation step could not be started for the specified reason. The relocation step was to start either a rebuild or a duplexing rebuild. The rebuild is used to activate a pending policy change and/or to adjust the location.

In the message text:

strname
Name of the structure for which information is recorded.
strrbldtype
One of the following:
REBUILD
The required type of structure rebuild processing was rebuild.
DUPLEXING REBUILD
The required type of structure rebuild processing was duplexing rebuild.
WAS NOT STARTED BECAUSE
The required structure rebuild process could not be started for the specified reason. The type of processing (strrbldtype) for structure rebuild can be either rebuild or duplexing rebuild.
reason
One of the following:
AN UNEXPECTED ERROR OCCURRED
The REALLOCATE process cannot be performed because an unexpected error occurred.
A STRUCTURE REBUILD PROCESS IS IN PROGRESS
The structure rebuild process is already in progress for the structure. Use the DISPLAY XCF,STR command to determine the type (rebuild or duplexing rebuild) and method (user-managed or system-managed) of the structure rebuild process.
THE 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.
THE STRUCTURE HAS NO ACTIVE CONNECTORS
The request would have resulted in a user-managed process, but the structure has no active connectors to participate in structure rebuild processing.
A REBUILD STOP IS IN PROGRESS FOR THE STRUCTURE
Rebuild stop is in progress for the structure.
AT LEAST ONE CONNECTOR DOES NOT SUPPORT REBUILD
At least one of the active connectors to the structure does not support rebuild.
NO SUITABLE COUPLING FACILITY FOR REBUILD WITH LOCATION=OTHER
The rebuild start request was rejected because LOCATION=OTHER was necessary and no other eligible coupling facility was found in the preference list.
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.
A DUPLEXING REBUILD IS 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.
THE 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.
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 rebuild if a CFRM policy change is pending, and either:
    • The policy changes does not involve updates to the SIZE or INITSIZE values, or
    • the policy change does involve updates to SIZE or INITSIZE and all the structure connectors specified IXLCONN ALLOWALTER=YES.
  • A potentially suitable coupling facility does not permit structure allocation.
CONNECTORS DO NOT SUPPORT SYSTEM-MANAGED PROCESSES
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.
AT LEAST ONE CONNECTOR HAS LOST CONNECTIVITY
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.
THE CFRM CDS 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)" implicitly formats a CFRM couple data set that supports both system-managed rebuild and system-managed duplexing rebuild.
A 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.
A CFRM ACTIVE POLICY DATA AREA COULD NOT BE OBTAINED
The requested system-managed process (for example, rebuild) cannot be initiated because the necessary CFRM active policy data area could not be obtained.
ALLOCATION OF Start of changeREBUILD NEW STRUCTURE FOR DUPLEXING REBUILD NOT FEASIBLEEnd of change
Allocation of the rebuild new structure instance in support of a duplexing rebuild is not feasible. Message IXC574I contains additional diagnostic information.

System action

The system continues the REALLOCATE process.

Operator response

Notify the system programmer.

System programmer response

Message IXC546I was issued by the REALLOCATE process to indicate that processing could not complete for a structure. The REALLOCATE process predetermines the necessary steps and if one or more of these steps cannot start structure rebuild processing then IXC546I is issued to provide the reason and type of structure rebuild process. Structure rebuild process type can be either rebuild or duplexing rebuild.

Use the DISPLAY XCF,STR,STRNAME=strname operator command to show the current state of the structure. Based on the current state of the structure use SETXCF and/or subsystem commands as required to activate a pending policy change or adjust the structure location.
