Diagnosing system data mover functions with the MVS MODIFY command

Use the MVS MODIFY command options that are described in this topic to diagnose and repair XRC. The following command sections give descriptions for valid operations and operands:

LISTSESS Operation
PATHS operation
REDISCOVER operation (XRC)
RESTART operation (XRC)

TERMSESS operation (XRC, CC)
XENDDUMP operation (XRC)
XRCTRAP/SUPRDUMP operation (XRC)

Note: The publication z/OS MVS System Messages, Vol 1 (ABA-AOM) describes the system data mover messages (which begin with ANT) and error codes. Diagnostic procedures outlined in this topic generate messages that begin with ANTX89.

If the messages are insufficient to diagnose your problem, issue the XQUERY TSO command to determine the status of the copy operation and volume pairs. If you need to report your problem to IBM® for further diagnosis, please include the following information with your report:

Merged console log from all attached systems. The SYSLOG contains a record of all XRC commands and messages, except for TSO commands.
Merged SYS1.LOGREC data sets from all attached systems.
For I/O related errors, a GTF trace of the failing command sequence on both the primary and secondary volumes.
For functional errors, generate an SVC dump of the SDM address spaces ANTMAIN, ANTAS000, and ANTASnnn. The value for the address space indicated by the ANTASnnn variable can be ANTAS000 or any of the address spaces numbered ANTAS001–ANTAS020.
Note: To determine which ANTASnnn address space is associated with the session, look at message ANTQ8200I that appears in the header of XQUERY reports for the session.

Attention: The MODIFY command is abbreviated as F. The format of the MODIFY command is as follows:
