4UsingtheAutoLUNGUI

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.

other than Auto LUN. Volumes being operated by these other programs cannot be operated by

Auto LUN.

details on the limitations when using Auto LUN logged in as a storage partition administrator,

see “Storage Partition Administrators Limitations” on page 25.
