IXCH0240E

Explanation
 CHECK(IBMXCF,XCF_CDS_SEPARATION)
found an exception. 
 The check found that the primary couple
data sets for types that should be separated reside on the same volume:
 CDS Type Volser Data Set Name 
-------- ------ -------------------------------------------- 
typename1 vol1   dsn1
typename2 vol2   dsn2 
typename3 vol3   dsn3

 Message IXCH0907I describes the complete couple data
set  configuration.  
 In the message explanation:
     typename1
The type of data contained in the couple data set
vol1
The volume on which the couple data set resides
dsn1
The couple data set name
typename2
The type of data contained in the couple data set
vol2
The volume on which the couple data set resides
dsn2
The couple data set name
typename3
The type of data contained in the couple data set
vol3
The volume on which the couple data set resides
dsn3
The couple data set name

System action
The system continues processing.

Operator response
Report this problem to the system programmer.

System programmer response
For maximum performance
and availability, the primary sysplex couple data set and the primary
CFRM couple data set should be placed on different volumes, and the
installation monitor I/O should rate to other couple data sets such
as LOGR to evaluate whether they also warrant placement on separate
volumes. By default, this check does not consider the LOGR couple
data set in evaluating couple data set placement. If the installation
requires to maintain the LOGR primary on a separate volume, update
the check with the parameter 'LOGR(YES)' to require the check to consider
the placement of the LOGR couple data set.
