IXCH0220E

Explanation
CHECK(IBMXCF,XCF_CF_SYSPLEX_CONNECTIVITY) found
an exception. 
The number of coupling facilities in the CFRM
active policy that have connectivity to all active systems in the
sysplex is ctdcfs - the parameter requires
at least mincfs. IXCH0908I and IXCH0909I have been
placed in the message buffer to indicate the coupling facilities in
the CFRM active policy and the systems that do not have connectivity
to those coupling facilities. 
 See accompanying messages IXCH0908I
and IXCH0909I for more information.
 When running in a parallel
sysplex environment, hardware redundancy should be provided for coupling
facilities. 
 In the message explanation:ctdcfs
Resolves to the number of coupling facilities in the CFRM active
policy that are connected to all active systems in the sysplex. 
parameter
Resolves to 'owner' or 'installation' to indicate whether the
default PARMS from  the HZSADDCHECK exit routine are in effect, or
user overrides are in effect. 
mincfs
 Resolves to the MINCFS value from the check PARMS.

System action
The system continues processing.

Operator response
Report this problem to the system programmer.

System programmer response
Determine why the required number
of coupling facilities are not available to all active systems in
the sysplex, and take appropriate action. There might be a problem
with a coupling facility definition in the active CFRM policy, a coupling
facility, or a system's connectivity to a coupling facility. 

Problem determination
 See IXCH0908I and IXCH0909I in the message
buffer that identify the active systems in the sysplex and the coupling
facilities in the sysplex (with information about their connectivity
to the active systems). 
On systems that are not connected to
a coupling facility, CHECK(IBMXCF,XCF_CF_CONNECTIVITY) provides additional
information through message IXCH0448E.
