Connecting External Storage Systems
XP External Storage enables you to use HP XP storage systems and other vendors' storage systems
(such as IBM or EMC) as connectable external storage systems. Hosts will recognize these volumes
as internal volumes of the original XP storage system. From this section onward, the original storage
system is called local storage system and a connected storage system is called the external storage
system.
External volume mapping is required for manipulating external volumes from a local storage system.
Mapping means assigning management numbers to the external volumes. These management
numbers are required for manipulating external volumes from a local storage system. By assigning
management numbers to the external volumes, the system administrator will be able to manipulate
not only internal volumes of a local storage system but also external volumes using Remote Web
Console. The management numbers consist of external volume group number - sequential number
(for example, E2- 1 , E50-3).

that are connected by XP External Storage. In the figure, the external storage system is connected
to the external port of the local storage system via a switch using the Fibre Channel interface. The
external port is a kind of port attribute that is used for XP External Storage. The external volumes
are mapped as internal volumes.
