Background initialization is a check for media errors on the drives when you create a virtual drive. It is an automatic operation that starts five minutes after you create the virtual drive. This check ensures that striped data segments are the same on all of the drives in the drive group.

在你建立一個虛擬磁碟時，後臺初始化用來檢查驅動器上的介質錯誤。當你建立完成虛擬驅動器後5分鐘自動開始這個操作。這個檢查確認驅動器組的所有驅動器的條帶資料段是相同的。

Background initialization is similar to a consistency check. The difference between the two is that a background initialization is forced on new virtual drives and a consistency check is not.

後臺初始化與一致性檢查類似。兩者的不同點是，後臺檢查對於新的虛擬驅動器是強制的，而一致性檢查不是。

New RAID 5 virtual drives and new RAID 6 virtual drives require a minimum number of drives for a background initialization to start. If fewer drives exist, the background initialization does not start. The background initialization needs to be started manually. The following number of drives are required:

新的RAID 5和RAID6虛擬驅動器達到最小的磁碟數量，才會開始後臺初始化。如果缺少，則後臺初始化不會（自動）啟動，需要手工啟動。下面是需要的驅動器數量：

 New RAID 5 virtual drives must have at least five drives for background initialization to start.

新的RAID5虛擬驅動器最少需要5塊驅動器才能開始後臺初始化。

 New RAID 6 virtual drives must have at least seven drives for background initialization to start.

新的RAID6虛擬驅動器最少需要7塊驅動器才能開始後臺初始化。

The default and recommended background initialization rate is 30 percent. Before you change the rebuild rate, you must stop the background initialization or the rate change will not affect the background initialization rate. After you stop background initialization and change the rebuild rate, the rate change takes effect when you restart background

initialization.

預設並且推薦的後臺初始化率是30%。在你修改重建率前，你必須停掉後臺初始化，或者修改比例不會影響到後臺初始化率。當你停掉後臺初始化並且更改了重建率後，當你重啟開始後臺初始化時更改的比例生效。
