linux系统下更换磁盘，但是对于惠普的阵列卡，使用常见的MegaCli 、storcli、percli都无法获取到磁盘信息，这时需要使用专用的工具ssacli。

查看raid卡信息(包括控制器状态、Cache状态、电池状态)
# ssacli ctrl all show status查看raid详细信息
# ssacli ctrl slot=0 show config detail查看raid状态
# ssacli ctrl slot=0 ld all show查看slot 0 阵列A 所有逻辑驱动器信息
# ssacli ctrl slot=0 array A ld all show查看slot 0 阵列A 所有物理驱动器信息
# ssacli ctrl slot=0 array A pd all show查看硬盘
# ssacli ctrl slot=0 pd all show status //查看物理硬盘状态
# ssacli ctrl slot=0 pd all show //查看物理硬盘创建raid10
# ssacli ctrl slot=0 create type=ld drives=1I:1:3,1I:1:4,2I:1:5,2I:1:6 raid=1+0用3，4，5号盘创建一个raid5阵列
# ssacli ctrl slot=0 create type=ld drives=1I:1:3,1I:1:4,2I:1:5 raid=5创建raid1
# ssacli ctrl slot=1 create type=ld drives=1I:1:1-1I:1:2 raid=1删除raid
# ssacli ctrl slot=1 array B delete forced缓存：
查看cache信息：
# ssacli ctrl all show config detail | grep -i cache关闭物理磁盘cache
# ssacli ctrl slot=0 modify drivewritecache=disable打开逻辑磁盘缓存
# ssacli ctrl slot=0 logicaldrive 2 modify caching=enable在没有电池的情况下开启raid写缓存
# ssacli ctrl slot=0 modify nobatterywritecache=enable设置读写百分比
# ssacli ctrl slot=0 modify cacheratio=10/90指示灯：
打开array B磁盘的led灯
# ssacli ctrl slot=0 array B modify led=on打开3号磁盘的led灯
# ssacli ctrl slot=0 pd 1I:1:3 modify led=on实战演习：
