AIX下更换rootvg磁盘与DIAG工具定位故障磁盘

 

AIX下rootvg镜像硬盘更换步骤，以下以rootvg中hdisk0故障为例： 

1、 卸载系统磁盘镜像

# unmirrorvg rootvg hdisk0 

2、 确认unmirror是否成功 

# lsvg -l rootvg

3、 从卷中删除物理卷hdisk0，可能会报0516-016，0516-884错误，原因是lg_dumolv（dump device）建在hdisk0上，lslv -l lg_dumolv可以查看

# reducevg rootvg hdisk0

4、修改dump

# sysdumpdev -P -p /dev/sysdumpnull 

5、重新执行删除物理卷hdisk0，可能会报0516-914错误，可以用smitty reducevg强制删除

# reducevg rootvg hdisk0

6、,删除坏硬盘，用diag工具中Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device  选项移除hdisk0  

# rmdev -dl hdisk0

7、插入新硬盘，cfgmgr，lspv识别的新磁盘如果无PVID，执行

# chdev -l hdisk0 -a pv=yes 

8、将更换后的硬盘添加如卷组当中

# extendvg rootvg hdisk0

9、用smit工具做mirrorvg镜像，选择 rootvg和hdisk0，同步模式选择background后台同步 

# smit mirrorvg  

10、添加启动镜像到新硬盘 

# bosboot -ad /dev/hdisk0

11、设置启动顺序

# bootlist -m normal hdisk0 hdisk1# bootlist -m normal -o  

12、重建dumplv,其中16为dump lv的PP数量，可以根据具体环境更改 

# mklv -t sysdump -y lg_dumplv rootvg 16 hdisk0

13、修改主设用dump device     

# sysdumpdev -Pp /dev/lg_dumplv 

14、查看rootvg

# lsvg -l rootvg

DIAG定位磁盘  

1．登陆AIX，执行#diag 

2．回车   
3．选择“Task Selection”  
4．按PgDn，选择“Hot Plug Task”  
5．选择“SCSI and SCSI RAID Hot Plug Manager”  
6．选择“Identify a Device Attached to a SCSI Hot Swap Enclosure Device” 
7．选择想判定位置的目标DISK，比如：hdisk0  
8．回车，这个时候去观察硬盘，你会发现硬盘的指示灯会显示“红色”，这个硬盘就是你需要判定的目标盘。  
9．如果想把这个有故障的硬盘从SCSI剔除，返回上一级菜单选择“Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device” 
10．然后选择想剔除的硬盘即可。

下面是本次实验的所有步骤：
