8 Maintaining the system
Some maintenance tasks are a response to behavior discovered during system monitoring. However,
you can also change certain settings to keep the system in tune with your changing requirements.
This chapter provides information and instructions for maintaining a Continuous Access Journal
system.
Pair maintenance—changing the pair-split option
You can change the option that specifies whether a pair-split operation that is triggered by pair
failure is applied to all the pairs in the mirror, or only to the affected pair. This option was first set
during the pair create operation.
