IXCH0265E

Explanation
      CHECK(IBMXCF,XCF_CF_STR_SCM_MINCOUNTS) found an exception.

      A check exception is raised when the check finds a coupling facility structure capable of 
      being assigned SCM (storage-class memory) but has a number of structure objects less than 
      the minimum required to allocate with SCM.

      A minimum number of structure objects is required to allocate a structure with a non-zero 
      SCMMAXSIZE. But once allocated, the coupling facility may initiate reapportionment in order to 
      perform migration from SCM. Such reapportionment may cause a structure object count to go below 
      the minimum.

      A check exception for a structure indicates that it should be duplexed and the number of structure 
      objects is less than the minimum required to allocate with SCM. When allocating a new structure 
      instance to establish duplexing for a structure that does not currently meet the minimum for a 
      non-zero SCMMAXSIZE, the new structure instance will be allocated with a zero SCMMAXSIZE - a 
      value that is inconsistent with the CFRM policy SCMMAXSIZE value.

      Message IXCH0930I in the message buffer lists structures allocated with the capability to use SCM, 
      their structure object minimums, and their count of structure objects allocated in real storage.

System action
The system continues processing.
Operator response
Report the problem to the system programmer.
System programmer response
      Perform the appropriate rebuild and/or stop duplexing processing to eliminate the minimum count 
      violation.

      For duplexed structures in which only one structure instance has a minimum count violation, stop 
      duplexing to keep the structure instance that does not have a minimum count violation. Then 
      re-duplex the structure. For example:

SETXCF STOP,RB,DUPLEX,STRNAME=strname,KEEP=OLD
SETXCF START,RB,DUPLEX,STRNAME=strname

      For duplexed structures in which both structure instances have a minimum count violation, stop 
      duplexing to keep the new structure instance. Then rebuild the structure to eliminate the minimum 
      count violation. Then re-duplex the structure. For example:

SETXCF STOP,RB,DUPLEX,STRNAME=strname,KEEP=NEW
SETXCF START,RB,STRNAME=strname
SETXCF START,RB,DUPLEX,STRNAME=strname

      For simplex structures, rebuild coupling facility structures with a minimum count violation to 
      eliminate the minimum count violation. Then duplex the structure. For example:

SETXCF START,RB,STRNAME=strname
SETXCF START,RB,DUPLEX,STRNAME=strname
