收到硬盘备件后，去客户现场更换硬盘。
查看P630系统信息，损坏硬盘hdisk1上没有paging信息，直接更换即可。
1、将hdisk1从P630系统镜像中拆除
#unmirrorvg rootvg hdisk1
2、将hdisk1从rootvg中剔除，并删除hdisk1在系统中的定义
#reducevg rootvg hdisk1
#rmdev -dl hdisk1
3、热插拔更换硬盘，重新识别新硬盘
#cfgmgr -v
4、给新硬盘分配PVID，将新硬盘加入rootvg，做镜像
#chdev -l hdisk1 -a pv=yes
#extendvg rootvg hdisk1
用smitty mirrorvg给hdisk0和hdisk1做镜像
5、在hdisk0和hdisk1上写入启动信息，并设置启动顺序
#bosboot -ad /dev/hdisk0
#r 0=1
#bootlist -m normal hdisk0 hdisk1
#bootlist -m normal -o查看正常。
6、保存errpt，并清除。
#errpt -a > /tmp/errpt091020.log
#errclear 0
更换硬盘完毕。
