Peer-to-peer remote copy (PPRC) is a hardware
feature of cached storage controls. TSO software operations enable
you to control PPRC operations. ERP messages indicate when PPRC has
suspended a volume pair, as well as the time and the reported hardware
indicator for the suspension. The publication z/OS MVS System Messages, Vol 1 (ABA-AOM) describes
the PPRC TSO and ERP messages.
If the messages are insufficient to diagnose your problem, issue
the CQUERY TSO command to determine the status of the copy path and
volume pair. 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 PPRC operations and messages.
- Merged SYS1.LOGREC data sets from all attached systems.
- For I/O related errors, a GTF trace of the failing operation sequence
for pairs involved with the error.
