4. Expansion
The expansion adds one or more HDDs to an existing logical drive to increase the capacity of the logical drive.
Note the following for the expansion:
Before expansion, data backup and synchronization should always be done.
Notice 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
