One of the trickier problems facing storage administrators is managing asynchronous replication such as IBM Global Mirror. With asynchronous replication, the disaster recovery site is by nature somewhat behind the primary. This is acceptable but if things fall too far behind, the mirror could be suspended which may be considered an outage.

This video will show you how you can assess the status of Global Mirror replication in a Globally Disbursed Parallel Sysplex environment. Data about the Global Mirror sessions is recorded in SMF type 105 records. By observing patterns and using drill downs, the root cause (Global Mirror RPO Issues) was identified and could be resolved.
