•
Maximum Initial Copy Activities: Number volumes that can be copied concurrently during an initial
copy operation. A value within the range of 1 to 128 can be specified. The default is 64 volumes.
Maximum Initial Copy Activities can impact the performance of the primary disk array, depending on
amount of I/O activity and number of pairs being registered at the same time. If Maximum Initial Copy
Activities is 64 volumes, you can limit the impact of initial copy activities on disk array performance.
For example, if you set the maximum initial copy activities to 64 volumes and add 65 pairs at the same
time, the primary disk array starts the first 64 pairs and does not start the 65th pair until one of the
pairs is synchronized. When you change the maximum initial copy activities setting, the new setting
applies to pairs created after the setting was changed, not to existing pairs.

Preparing for disaster recovery
The type of disaster and the status of the Continuous Access XP Journal volume pairs determines the best
approach for disaster recovery. Unfortunately, some disasters are not so “orderly” and involve intermittent
or gradual failures occurring over a longer period of time. You should anticipate and plan for all types of
failures and disasters.
The major steps in preparing for disaster recovery are:
