Users registered in an external authentication group have the permissions of the user group to which
users are assigned. By specifying roles, resources that belong to a resource group for which a user
has permission to reference or perform operations on are displayed. The user can operate, or reference
information for, the displayed resources.

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.
The values below ensure the operation of Tiered Storage Manager in Legacy mode. Performance
might slow down or memory might become insufficient if a value exceeds the maximum value.
