another program. XX is an ID which is given by this program.
A migration plan executed by a program other than Auto LUN is indicated by the (green) icon
displayed in the LDEV column and by Other[XX] displayed in the Owner column. You cannot
delete such a migration plan by the Delete button.

If you select a migration plan in blue (that is a migration plan that is not applied to the storage
system yet) and click the Delete button, the migration plan is deleted immediately.
If you select a migration plan in black (that is a migration plan that is waiting for execution or is
being executed) and click the Delete button, the DEL column displays the character D and the
selected migration plan will not be deleted until you click the Apply button.
The Delete button does not take effect when both blue and black migration plans are selected.
Confirm that only blue or black migration plans are selected before you select Delete.
Note: You cannot use the Delete button to delete a migration plan executed by a program other
than Auto LUN (such as RAID Manager).
Caution: If you delete a migration plan which is being executed, the data in the target volume is
not guaranteed.
• The Apply button applies manual migration plans in the list to the storage system to start volume
migrations.
• The Close button closes the Manual Plan window.
• The Refresh button updates information in the Manual Plan window. The button updates the
displaying of the tree after the execution of manual migration plan.
