Importing from External Device without Replication License
Figure 105. Select External Disk
2 From the shortcut menu, select Import from External Device. The system warns you
that you must have sufficient space on the Storage Center system to import from an
external device.
Note Importing data from an external device requires the Storage Center to read all blocks
to the entire size of the volume. Depending on RAID selection this may consume up
to two times the storage of the volume on your system.
Thin import works by not writing data if no previous page exists for the data in question, and
the data being written is all zeros. This saves significant space for many sparse data sets.
If you have sufficient space, click Continue. Select an existing volume or create a new
volume to be the destination volume for the remote volume. To create a volume, refer to
Creating a Volume on page 67 .
