If a log dataset becomes full, delete and re-define the log stream by following the procedure below.
The log dataset is deleted when the log stream is deleted. Note that even when the log dataset
becomes full, CLI command processing continues, but no data will be output to the logs.
1.
Temporarily stop the CLI command execution.
#
2.
Use the YKLOGCP command to output all the log data to an external dataset.
3.
By the IXCMIAPU utility, specify the DELETE LOGSTREAM NAME(log-stream-name) parameter
to delete the Business Continuity Manager log stream.
4.
Re-define the log stream.
5.
You can now log back on to TSO/E again and execute CLI commands.
#
You cannot delete the log stream while CLI commands are executing. As a result, be sure to
temporarily stop a CLI command execution to delete the log stream. If you cannot stop a CLI
command execution, execute the FORCE IXGLOGR,ARM command to stop the system logger
service, execute the S IXGLOGRS command to restart the system logger service, and then delete
the log stream.

Performing Operations When a Failure Occurs for a Volume in a Copy Group
When a volume in a copy group suffers a hardware failure, you must remove the cause of the
failure and perform a recovery as soon as possible. Use the methods shown in
if you still need to perform the operations after a failure occurs, but before a recovery can be
performed.
