Workflow for resynchronizing ShadowImage pairs

Complete the following steps to resynchronize SI pairs:

1. Place the S-VOL offline.

2. Split or suspend the pair.

 The pair can also be in the process of being Quick Split (PSUS(SP)/PSUS status).

3. (Optional) If you are concerned about host server I/O performance, check to make sure the I/O load is light.

For more information about checking I/O performance, see the Command Suite User Guide.

4. Resynchronize the pair (see Resynchronizing or restoring ShadowImage pairs).
