Rebuilding an Array
By checking array status you can determine whether maintenance is necessary. An array is in one of
four statuses: normal, degraded, damaged, rebuild. The status is normal if no physical disk is lost.
When the number of physical disks lost reaches the specified value, the array is considered damaged.
The status between normal and damaged is degraded. A degraded array can be recovered to normal
status if you rebuild it.
NOTE!
Take RAID 5 that consists of 4 disks as an example. The array is degraded when one disk is lost. And
when two disks are lost, the array is damaged.
After an array becomes degraded, it can be rebuilt automatically within ten minutes if a hot spare
disk is available, and if the capacity of the hot spare disk is not less than that of any disk in the array.
A degraded array without a hot spare disk can only be rebuilt manually under
