Upgrading the load source disk unit with local mirroring using non-configured disk units

This checklist shows the sequence of tasks to upgrade your load source disk unit (unit 1) and the mirrored load source with disk units that have equal capacity, are at least 70-GB, and are mirror protected. The disk units that are replaced in this procedure are discarded.

Print a copy of this checklist. Check off the configuration tasks as you perform them. This checklist provides an important record of your actions. It may help you diagnose any problems that occur.

Before you begin

Evaluate your disk configuration and record your answers. The information entered in the Before you begin table is needed to answer the questions in the Load source planning section.
