5. After the task completes, the wizard return s to the Volumes window. You can list volumes 
mapped to the host by navigating to Hosts → Mappings, as shown in Figure 7-39

6. List of volumes mapped to all hosts is displayed, as shown in Figure 7-40. 
Figure 7-40   List of volumes mapped to hosts
To see volumes mapped to clusters instead of hosts, change the value that is shown in the 
upper left corner (see Figure 7-41 on page 282) from Private Mappings to Shared 
Mappings.
The host can now access the mapped volume. For more information about discovering the 
volumes on the host, see Chapter 8, “Hosts” on page 317.
7.7  Migrating a volume to another storage pool
IBM Spectrum Virtualize enables online volume migration with no applications downtime. 
Volumes can be moved between storage pools without affecting business workloads that are 
running on these volumes.
There are two ways to perform volume migration: by using the volume migration feature and 
by creating a volume copy. These approaches are described next.
7.7.1  Volume migration using migration feature
The migration process is a low priority process that does not affect the performance of the 
IBM Spectrum Virtualize system. However, as subsequent volume extents are moved to the 
new storage pool, the performance of the volume is determined more by the characteristics of 
the new storage pool.
Note: You can use the filter to display only the wanted hosts or volumes.
