Figure 8 – 8: Completion of Add Drive Function
The added capacity will be automatically included, meaning that
you do not have to "expand logical drive" later. Map the added
capacity to another host ID/LUN to make use of it.
As diagrammed above, in "View and Edit Host LUN," the original
capacity is 9999MB, its host LUN mapping remains unchanged, and
the added capacity appears as the second partition.
IMPORTANT!
• Expansion by adding drives can not be canceled once started. If
power failure occurs, the expansion will be paused and the
controller will NOT restart the expansion when power comes
back on. Resumption of the RAID expansion must be performed
manually.
• If a member drive of the logical drive fails during RAID
expansion, the expansion will be paused. The expansion will
resume after the logical drive rebuild is completed.
8.4 Mode 2 Expansion:
Copy and Replace Drives with Drives of
Larger Capacity
You may also expand your logical drives by copying and replacing
all member drives with drives of higher capacity. Please refer to the
diagram below for a better understanding. The existing data in the
array is copied onto the new drives, and then the original members
can be removed.
