starts initializing.
4.2.2 Array Exception
Purpose:
If HDD failure occurs, array degrades. When more HDDs fail, array fails. Degraded array can keep working.
However, failed array cannot work. Notification area will notify you once array degraded or failed. Refer to
following table for array degraded and failed condition.
Table 4. 4 Array Degraded Condition

RAID 50
If array in storage pool degrades, physical volume degrades.
If array in storage pool fails, physical volume fails.
4.2.3 Rebuilding Array
Purpose:
Rebuilding refers to the process of using a normal HDD or array to virtually place a failed HDD in degraded re a
array. The normal HDD can be hot spare HDD, newly inserted HDD, and so forth.
During rebuilding process, if the rebuilding HDD fails, the array stays degraded.
During rebuilding process, if a normal HDD in array fails, the array becomes failed.
During rebuilding process, if I/O error occurs to the rebuilding HDD, you need to change rebuilding HDD.
