1、HP Smart Storage Administrator 擴容陣列的方法By Ju,zhen-wen05/15/2014目錄實驗環境：1進入SSA:1Add drive 增加驅動器Expand Array擴容陣列10Move drive移動陣列11Mirrir array鏡像陣列11Shrink Array收縮陣列12Replace Array更換陣列13實驗環境：機型:DL380p Gen8IP版本:1.5以上進入SSA:服務器自檢時，通過F10進入IP，并按下圖選擇：Perform Maintenance進入Hp smart storage administrator。（SSA）如下圖

2、：進入SSA后第一個界面如下圖：選擇：configure在當前界面看到一塊硬盤做的raid 0。Unassigned drives 有2個.確認緩存cache和電容capacitor，點擊右下角view more details。看到了cache 大小1024MB,電容的數量為1Close之前界面，在主界面點擊manage data drives.可以看到如下3個選項：Expand Array擴容陣列Increase the capacity of an existing array by adding currently existing unassigned drives to it.No

3、te: Only physical drives of the same size (within 10 percent) should be added to the same array because all the drives within an array are reduced to the size of the smallest physical drive. For example, an array with three 300 GB drives and a 750 GB drive would be viewed as being the same size as a

4、n array with four 300 GB drives since the 750 GB drive is seen as a 300 GB drive.Expand array has the following options:Expansion TypeFor arrays that contain RAID 50 or RAID 60 logical drives, array expansion is constrained by the number of drives in the array and the number of parity groups in the

5、existing logical drives. The transformation type refers to the different methods that apply to these logical drives:Increase Number of Parity Groups: the required number of physical drives will be added to form new parity group(s) for the array.Increase Number of Drives in Each Parity Groups: the re

6、quired number of physical drives will be added evenly to each existing parity group.The notes on the top of the page will tell you how many drives are needed for each transformation type.Physical Drive SelectionSelect the physical drives that you want to use in the array from the unused drives liste

7、d.擴容：通過向現有陣列添加當前現有的未分配驅動器來增加陣列的容量。注意: 只應將相同大?。ㄔ?10% 以內）的物理驅動器添加到同一陣列，因為陣列中的所有驅動器都減少為最小物理驅動器的大小。 例如，具有三個 300 GB 驅動器和一個 750 GB 驅動器的陣列會被視為與具有四個 300 GB 驅動器的陣列大小相同，因為 750 GB 驅動器會被視為 300 GB 驅動器。擴展陣列有下列選項: 擴展類型 對于包含 RAID 50 或 RAID 60 邏輯驅動器的陣列，陣列擴展受到陣列中的驅動器數和現有邏輯驅動器中的奇偶校驗組數的約束。 轉換類型是指適用這些邏輯驅動器的不同方法：增加奇偶校驗組數

8、： 添加所需數量的物理驅動器，為陣列形成新的奇偶校驗組。增加各奇偶校驗組中的驅動器數： 向每個現有奇偶校驗組均勻地添加所需數量的物理驅動器。頁面頂部的說明將告知您每種轉換類型需要多少個驅動器。物理驅動器選擇:從未使用驅動器列表中選擇要在陣列中使用的物理驅動器。 Move drive移動陣列The Move Array operation allows you to transfer the contents of a disk array from one set of physical drives to a second set of physical drives. Please not

9、e the following conditions and restrictions for the Move Array operation:The destination physical drive set must have the same number of elements as the source physical drives set.The array type (SAS or SATA) must remain the same.The destination drive(s) must have enough capacity to hold all the log

10、ical drives present in the source array.Note: As is the case with array creation and expansion, the usable space in all drives will be reduced to the size of the smallest physical drive in the destination disk set.使用“移動陣列”操作可以將磁盤陣列的內容從一組物理驅動器轉移到另一組物理驅動器。 請注意，“移動陣列”操作有以下條件和限制：目標物理驅動器集與源物理驅動器集的元素數必須相同

11、。陣列類型（SAS 或 SATA）必須保持不變。目標驅動器必須有足夠的容量來容納源陣列中的所有邏輯驅動器。注意: 像創建和擴展陣列時一樣，所有驅動器中的可用空間將縮減至目標磁盤集中最小物理驅動器的大小。 Mirrir array鏡像陣列The Mirror Array operation allows you to double the number of data drives in the array and convert all logical drives in the array to RAID 1, or RAID 1+0.This option is only availabl

12、e if the array contains only RAID 0 drives.When the total number of data drives in the resulting array is 2, the resulting RAID level is RAID 1. When the total number of data drives is 4 or more, the resulting RAID level is RAID 1+0.Note: Some controllers may not support this option or may require a

13、 license key to enable this feature.鏡像陣列使用“鏡像陣列”操作可以讓陣列中的數據驅動器數量倍增，并將陣列中的所有邏輯驅動器轉換為 RAID 1 或 RAID 1+0。僅當陣列僅含 RAID 0 驅動器時，此選項才可以使用。最終產生的陣列中的數據驅動器總數為 2 時，最終的 RAID 級別為 RAID 1。數據驅動器總數為 4 個或更多時，最終的 RAID 級別為 RAID 1+0。注意: 有些控制器可能不支持此選項，或者需要許可密鑰來啟用此功能。Shrink Array收縮陣列The Shrink Array operation allows you to

14、 remove drives from an existing array. The following conditions apply:The array must have enough free space to accommodate all existing logical drives.You may not remove drives from the array if the resulting number of drives will not support the fault tolerance (RAID level) of any existing logical

15、drive. For example, if you have an array with 4 physical drives and a RAID 5 logical drive, you may remove at most 1 drive since RAID 5 requires at least 3 physical drives.If the array contains a RAID 1+0 logical drive, you may only remove an even number of drives.If the array contains a compound RA

16、ID (RAID 50 or RAID 60) logical drive, drives may only be removed in multiples of the number of parity groups. For example, an array with 10 physical drives and a RAID 50 logical drive may be shrunk by removing 2 or 4 disks only.Note: Some controllers may not support this option or may require a lic

17、ense key to enable this feature.使用“收縮陣列”操作可以從現有陣列中刪除驅動器。 以下條件適用：陣列必須具有足夠的可用空間來容納所有現有邏輯驅動器。如果生成的驅動器數不支持任何現有邏輯驅動器容錯（RAID 級別），則您可能不能從陣列中刪除驅動器。 例如，如果陣列具有 4 個物理驅動器 和一個 RAID 5 邏輯驅動器，您最多可以刪除 1 個驅動器，因為 RAID 5 需要至少 3 個物理驅動器。如果陣列包含一個 RAID 1+0 邏輯驅動器，則只能刪除偶數個驅動器。如果陣列包含復合 RAID（RAID 50 或 RAID 60）邏輯驅動器，則只能按奇偶校驗組數的

18、倍數刪除驅動器。 例如，含 10 個物理驅動器和一個 RAID 50 邏輯驅動器的陣列收縮時只能刪除 2 個或 4 個磁盤。注意: 有些控制器可能不支持此選項，或者需要許可密鑰來啟用此功能。Replace Array更換陣列 The Replace Array operation allows you to transfer the contents of an array to an existing empty array or a new array. All logical drives from the source array will be transferred. The or

19、iginal array will be deleted and its data drives will be freed as unassigned drives. The drive types at source and destination arrays can be different. Please note the following conditions and restrictions for the Replace Array operation:The destination array must have the same number of physical dr

20、ives as the source array to be replaced.Both the source and the destination arrays must be in OK state. All the existing logical drives in the source arrays must be in OK state.The destination array must have enough capacity to hold all the logical drives present in the source array.Note: Replacing an array is a time-consuming operation for the following reasons: The data in every logical drives of the source array has to be copied to the destination array; the co
