HP StorageWorks XP Remote Web Console Software - Manual (Page 37)

Figure 18 Graph Window
◦ Source LDEV lets you specify the source volume (that is, the volume that you want to
migrate). To the right of the text box is the following:
– The current usage rate for the parity group that the source volume belongs to.
– An estimated usage rate for the parity group after a proposed volume migration.
If you specify an external volume as a source volume, XP Auto LUN cannot calculate the
estimated usage rate after migration. In this case, a hyphen (-) appears instead of a value.
◦ Target (Reserved) LDEV lets you specify the target volume (that is, the location to which
you want to migrate the source volume). To the right of the text box is the following:
– The current usage rate for the parity group that the target volume belongs to.
– An estimated usage rate for the parity group after a proposed volume migration.
If you specify an external volume as a target volume, XP Auto LUN cannot calculate the
estimated usage rate after migration. In this case, a hyphen (-) appears instead of a value.
◦ The line graph illustrates the past usage rates of the source volume and the target volume.
◦ The Close button closes the Graph window.
•
The Set button adds a new manual migration plan to the list. The new manual migration plan
consists of the volumes selected in Source LDEV and Target (Reserved) LDEV.
•
List: Each row in the list indicates a manual migration plan, which is a pair consisting of a
source volume and the corresponding target volume, created in the Manual Plan window.
Before a migration plan is applied to the storage system, it is displayed in blue; and after a
migration plan is applied (or during execution) to the storage system, it is displayed in black.
