BPXF215E UNIX SYSTEM SERVICES IS UNABLE TO ACCESS ITS COUPLE SET. AN ATTEMPT TO READ FROM THE DATA SET ENDED WITH A RETURN CODE OF `retcode` AND A REASON CODE OF `reason`.

Explanation
An error occurred when attempting to access the z/OS UNIX System Services couple data set. Access to the type BPXMCDS couple
data set is required in order for z/OS UNIX System Services sysplex
operations to continue.

In the message text: 

retcode

The return code received from the IXCXCDSI macro.

reason

The reason code obtained from the invocation of the macro. The following table explains the
possible return and reason codes:

Explanation

C

Environmental error

4

DSPSERV failed to create the XCF data space necessary to handle
this request.

8

ALESERV failed to add to the PASN the XCF data space necessary to
handle this request.

C

STORAGE failed to obtain the storage necessary to handle this
request.

10

The couple data set for this data type is not currently in
use.

14

TCBTOKEN failed to create a token for the current task.

18

A duplicate request was received. This could be a ReadSerialized
for a particular record/subrecord from a task that already owns it.

10

Failure in XCF processing.

System action
All services requiring access to the data set will be delayed until the data set is made
available. For example, one or more of the following file system functions may be delayed: file
system initialization, mount processing, unmount processing or partition recovery. Access to the
couple data set will be attempted every 10 seconds until successful. Once access to the couple data
set is restored, the delayed operation will resume. 

Operator response
Contact your system programmer.

System programmer response
Review the return code and reason code, correct the error and make a couple data set available.
z/OS UNIX System Services uses a type BPXMCDS couple data set. Refer
to z/OS UNIX System Services Planning for the procedure to create an OMVS
couple data set. Use the D XCF,COUPLE,TYPE=BPXMCDS system command to display the status of the
z/OS UNIX System Services couple data set. Once the couple data set
is defined and online, use the SETXCF COUPLE system command to enable the couple data set.
