From the host, you can access the external storage system volumes that have not been mapped as

internal volumes. There is no restriction. Figure 13 (page 29) illustrates using existing data in a

mapped external volume.

Interoperability with other Products and Functions

You can use XP disk array program products to use and manage the external volumes you have

set using XP External Storage. For the operations and notes on each program product, see the

respective user's guides.

LUN Manager and Configuration File Loader

If you set the emulation type for the open system as you map an external volume, you need to set

the LU path for the mapped volume using LUN Manager.

Consider the following for the Configuration File Loader function:

• You can set the LU path definition for the external volume (add, delete, or change LU paths).

• You can set the command device for the external volume (add or delete the setting).

• The setting of the channel adapter (CHA) mode, host group, and WWN for the external port

is not supported. When an external volume is mapped through that external port, the setting

operation of the topology is not available, either.

LUN Expansion (LUSE)

Consider the following for LUN Expansion (LUSE):

• The internal volume in the local storage system and the external volume cannot be combined

to form a LUSE volume.

• Do not combine LDEVs of multiple external volumes to create a LUSE volume. Only the LDEVs

in the same external volume can be used to configure the LUSE volumes.

• All external volumes in a LUSE volume must be in the same Cache Mode.
