The scenario requires modifying an existing storage group to add three new volumes and change its Service Level. The provided image displays the final "Summary" screen of the "Modify Storage Group" wizard within Unisphere for PowerMax. This screen appears after the administrator has configured all the required changes: increasing the volume count from two to five (adding three new 100 GB volumes) and changing the Service Level from Gold to Platinum. To commit these changes and have the system execute the provisioning task, the final step is to click the "Run Now" button. This action submits the job to the PowerMax array.
