Figure 2-8 illustrates an unplanned outage to a coupling facility LPAR. In a high
availability configuration, the loss of a CF LPAR will not cause a DB2 or
application outage. There may be brief spikes in response time or elapsed time
during the CF recovery process, but the DB2 members, and the applications
accessing DB2 data, will continue to execute.

The DB2 and IRLM members cooperate to rebuild the structures to the other CF.
See 6.2, “Component failure” on page 109 for more information on DB2
operations in failure situations
