4. Expansion

The expansion adds one or more HDDs to an existing logical drive to increase the capacity

of the logical drive.

Notice
Note the following for the expansion:
Before expansion, data backup and synchronization should always be
done.
During expansion, the processing rate is decreased due to much load.
Expansion is unavailable for a logical drive in the critical state. Before
the expansion, rebuild should be done to recover logical drive.
During expansion, do not shut down or reboot the server. If the server is
shut down by an unforeseen accident such as power interruption, turn on
the power again as soon as possible. After rebooting the system, the
expansion is automatically started.
For the expansion, WebPAM must be installed.
For the detailed operation, refer to the online manual "Web-based
Promise Array Manager User’s Guide" saved in the "S-ATA Array
Management Software" CD-ROM coming with the card.
