HP Smart Storage Administrator –扩容阵列的方法By Ju,zhen-wen05/15/2014实验环境：机型:DL380p Gen8IP版本:1.5以上进入SSA:服务器自检时，通过F10进入IP，并按下图选择：Perform Maintenance进入Hp smart storage administrator。（SSA）如下图：进入SSA后第一个界面如下图：选择：configure在当前界面看到一块硬盘做的raid0。Unassigneddrives有2个.确认缓存cache和电容capacitor，点击右下角viewmoredetails。看到了cache大小1024MB,电容的数量为1Close之前界面，在主界面点击manage data drives.可以看到如下3个选项：Expand Array扩容阵列Increase the capacity of an existing array by adding currently existing unassigned drives to it.Note: 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 an array with four 300 GB drives since the 750 GB drive is seen as a 300 GB drive.Expand array has the following options:ExpansionTypeFor 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 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 required 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 listed.扩容：通过向现有阵列添加当前现有的未分配驱动器来增加阵列的容量。注意: 只应将相同大小（在 10% 以内）的物理驱动器添加到同一阵列，因为阵列中的所有驱动器都减少为最小物理驱动器的大小。 例如，具有三个 300 GB 驱动器和一个 750 GB 驱动器的阵列会被视为与具有四个 300 GB 驱动器的阵列大小相同，因为 750 GB 驱动器会被视为 300 GB 驱动器。扩展阵列有下列选项: 扩展类型 对于包含 RAID 50 或 RAID 60 逻辑驱动器的阵列，阵列扩展受到阵列中的驱动器数和现有逻辑驱动器中的奇偶校验组数的约束。 转换类型是指适用这些逻辑驱动器的不同方法：增加奇偶校验组数： 添加所需数量的物理驱动器，为阵列形成新的奇偶校
