Figure 12 Storing the New Data in the Mapped External Volume
Using Existing Data in the Mapped External Volume
To use the existing data in the mapped external volume from the host that is connected to the local
storage system:
1. Store the data from the host that is connected to the external storage system to the volume in
the external storage system.
2. Map the volume containing data in the external storage system as an internal volume of the
local storage system using External Storage.
When you map the external volume, set the attributes of the mapped volume as follows:
• Emulation
type: OPEN-V
For information on mapping operations, see
“ Mapping an External Volume Automatically ” on page 69.
Note: You have to set the emulation type to OPEN-V to read the existing data in the mapped
external volume from the local storage system side.
3. Set the LU path from the Target port to the mapped volume to perform the host I/O operation.
After the LU path is set, the host I/O operation to the mapped volume can be initiated.
Note: Make sure that you do not access the external volume, which has been mapped as a internal
volume, from the host that is connected to the external storage system. Also make sure that you do not
access the mapped external volume using the function (for example, copy function) of the external storage
system. Once you have mapped an external volume as an internal volume, you can access the mapped
external volume only from the local storage system side.
Note: From the host, you can access the external storage system volumes that have not been mapped
as the internal volumes. There is no restriction.
