4 Configuring Business Copy
This chapter provides instructions for configuring BC.
Workflow for setting up Business Copy
Set up BC before you create the copy pair.
Use the following workflow to set up BC:
1. Prepare the volumes for BC (see “Preparing volumes for BC” (page 30)).
2. (Optional) Enable the system options (see “Enabling system options” (page 31)).
Preparing volumes for BC
You must set up and prepare the P-VOLs and S-VOLs for BC pairing before creating BC pairs. The
volumes you plan to use must meet the requirements for pair volumes.
The following table provides example volumes to guide you in preparing for BC volumes.

System options that affect performance
The following system options affect performance, which you can enable and disable:
• Swap & Freeze. Enable this system option to suppress copy operations (the S-VOLs to remain
unchanged) during pair restoration using Quick Restore. Differential data is not copied to the
new S-VOL.
• HOST I/O Performance. Enable this system option to suppress copy operations regardless of
the workload and to maximize server I/O performance.
NOTE: This system option increases the copy time, which slows copy operations.
