Reserving Migration Destinations For Volumes
To migrate volumes, you must reserve disk spaces (actually, volumes) that can be used for migration
destinations. You must reserve volumes regardless of migration methods (manual migration or automatic
migration). Migration will not take place when no volume is reserved.
Throughout the storage system documentation set, the term reserved volume is used to refer to a volume
that is reserved for use as a migration destination. Volumes reserved by Auto LUN are indicated by blue
icons. Also, the term normal volume is sometimes used to refer to a volume that is not reserved as a
migration destination.
To reserve a volume as a migration destinations:
1. Start Auto LUN (see “ Starting Auto LUN ” on page 41) and select the Attribute tab in the Auto
LUN window ( Figure 18 on page 34).
2. In the tree, locate a volume that you want to use as a migration destination.
To locate a volume, first double-click an HDD class (or the External Group folder) in the tree
to display a list of parity groups (or external volume groups). Next, click a parity group (or
an external volume group).
The list on the right displays a list of volumes in that group.
3. In the list on the right of the tree, locate volumes preceded by the icon. From those volumes,
select the desired volume and right-click it.
Note: To reserve two or more volumes, you can select the desired volumes and right-click the
selection.
4. Select Reserved LDEV from the pop-up menu.
The icon changes to a blue
icon.
