IXCH0222E

Explanation
 CHECK(IBMXCF,XCF_CF_STR_NONVOLATILE) found an
exception. 
An allocated coupling facility structure was connected
to with IXLCONN NONVOLREQ=YES, requesting non-volatility and failure-isolation
from connectors. The structure is not in a coupling facility with
non-volatile storage, or a connector to the structure is not failure-isolated
from the structure instances.
See accompanying message IXCH0910I
for more information. 
 For applications that request it, structures
should be allocated in a coupling facility that provides non-volatility
and failure-isolation from connectors.

System action
The system continues processing.

Operator response
Report this problem to the system programmer.

System programmer response
If all coupling facilities containing
the structure are volatile, move a structure instance to a non-volatile
coupling facility that provides failure-isolation from connectors,
 or accomplish the same result by changing a coupling facility to
be non-volatile. Only one structure instance of a duplex structure
needs to be in a non-volatile coupling facility for the structure
to be considered non-volatile. The following system commands might
provide additional information:        

  DISPLAY XCF,CF,CFNAME=cfname  

  DISPLAY XCF,STRUCTURE,STRNAME=strname     

If a connector
is not failure-isolated from the structure instances, determine the
action needed to  provide failure-isolation. Note that a connector
only has to be failure-isolated from one structure instance of a duplexed
pair of structure instances to be considered failure-isolated. The
following system command might provide additional information:   
  DISPLAY XCF,STRUCTURE,STRNAME=strname,CONNAME=conname 

Problem determination
See IXCH0910I in the message buffer that
identifies the coupling facility structure and connectors that caused
the exception.
