Recommended Applications According To Hdd Type - HP StorageWorks XP24000 User Manual

Do not map a volume from an external storage system if it has already been mapped as
internal storage in another storage system.
When an external storage system that has an ownership is connected to a storage system,
configure the cross-subsystem path to the primary controller in the external storage system as
primary path.
Ownership is an exclusive right to control volumes. A controller that has an ownership is called
a primary controller. If a cross-subsystem path to a controller without ownership is configured
as primary path, the ownership will be transferred and it may affect the performance.
