更换磁盘步骤：
一、确认磁盘是否损坏
#lspv
发现hdisk2 为非PV，应为没有PV ID。
#chdev -l hdisk2 -a pv=yes //改命令执行失败，应该磁盘数据写不进去
如果磁盘上面没有数据，也可以通过 dd 命令测试磁盘是否可写。不可写，可以确定磁盘已经损坏了。
#rmdev -dl hdisk2
二、开始更换磁盘
1、 List Hot Swap Enclosure Devices
查看可以热插拔的磁盘槽位。
2、 Identify a Device Attached to a SCSI Hot Swap Enclosure Device
标志损坏磁盘的位置
3、 Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device
执行该命令，准备更换磁盘
4、插入磁盘
5、 Configure Added/Replaced Devices
相当于 cfgmgr 命令，从新查找硬件
