4 Using the Auto LUN GUI
Using the Auto LUN Windows
Auto LUN can be used to balance workloads among hard disk drives and thus remove bottlenecks from
the system. Auto LUN can migrate volumes from the current parity group to another parity group. Volume
migrations can be performed manually (by the system administrator) or automatically by Auto LUN.
In addition, Auto LUN can also migrate external volumes in external volume groups. However,
external volumes can be migrated manually by the system administrator, but they cannot be migrated
automatically by Auto LUN. For details on external volume groups and external volumes, see the HP
StorageWorks XP24000 Performance Monitor User's Guide.
Note:
• From an open-system host, users can also use RAID Manager to perform manual volume
migration by using commands. To perform volume migration by RAID Manager, Auto LUN
should be installed on the storage system. For details on manual volume migration by using RAID
Manager, see “ Sample Volume Migration ” on page 45. For details on RAID Manager, see HP
StorageWorks XP RAID Manager User’s Guide.
• The Auto LUN windows also display the statuses of volume migration performed by programs
other than Auto LUN. Volumes being operated by these other programs cannot be operated by
Auto LUN.
• If the user type of your user ID is storage partition administrator, you cannot use Auto LUN. For
details on the limitations when using Auto LUN logged in as a storage partition administrator,
see “ Storage Partition Administrators Limitations ” on page 25.
This section describes options, buttons and other components in Auto LUN windows.
Manual Plan Window of the Auto LUN
When you click the Auto LUN button in the Performance Management window, Auto LUN starts and
the Manual Plan window of the Auto LUN is displayed. The Manual Plan window lets you create and
execute manual migration plans.
For details on operations in this window, see “
Migrating Volumes Manually ” on page 42.
