Notes on performing data migration in Legacy mode

The number of volumes that are candidates for migration target volumes are narrowed down and
displayed when selecting a migration-target volume. If you want to display all the volumes, in the

server.properties

file of Tiered Storage Manager server, set a value for the

server.migration.plan.candidateVolumeCountLimit

property.

For details on the properties file, refer to the HP P9000 Command View Advanced Edition Suite
Software Administrator Guide
. To avoid insufficient memory, we recommend that you use the default.
