Use the following steps to collect and analyze messages
and logrec records about the problem.
Procedure
Use time stamps to select messages and software, symptom,
and hardware logrec records related to the problem. Look in the following:
OPERLOG or SYSLOG
VERBEXIT MTRACE dump output, which shows the buffer for system
messages
VERBEXIT LOGDATA dump output, which formats the logrec buffer
Logrec data set, formatted by EREP
Use the COPYCAPD command to check for
any SVC dumps captured in dataspaces that did not have a chance to
get written out to a dataset prior to the system hang. For example:
Number Time stamp Title

These
SVC dumps can be extracted into dump data sets using the COPYCAPD command
and then diagnosed individually. Go to Diagnosing an abend.
