The Manual Plan window displays the following:
• Monitoring Term: Displays the monitoring period specified in the Performance Management
window.
Auto LUN analyzes disk usage information collected by Performance Monitor, Performance
Control, or Auto LUN during the monitoring period, and then calculates estimated usage rates
of the source and target parity groups after a proposed volume migration. The program does
not calculate estimated usage rates of external volume groups.

Group folder contains icons of parity groups, and the External Group folder contains icons
of external volume groups.
