Figure 4-3: Expand RAID Set 

4.4.4  Activate Raid Set 

If a hard drive is removed from the disk array while it is powered down, the RAID set that the 
drive belongs to will have a status of “Incomplete” when the disk array is powered on. RAID sets 
in “Incomplete” mode are inactive and cannot be accessed. To activate a RAID set in 
“Incomplete” mode, select the RAID set in the “Activate Raid Set” page (Figure 4-4) and click 
“Submit” to change it to “Degraded” mode.
