1 Rootvg做镜像
1.1 Rootvg做镜像要求
在安装完操作系统，配完应用后，我们一般要给rootvg做镜像，做rootvg镜像的硬盘必须和rootvg的硬盘空间大小相同，转速相同的同一型号内置SCSI硬盘。可通过下面这些命令来确认：
lsdev -Cc disk 确定主机中有几块硬盘，有几块内置硬盘
# lsdev -Cc disk [IBMP740-1:root:/]#lsdev -Cc disk hdisk0 Available 00-00-00 SAS Disk Drive hdisk1 Available 00-00-00 SAS Disk Drive hdisk2 Defined 07-00-02 EMC CLARiiON FCP LUNZ Disk hdisk3 Defined 07-00-02 EMC CLARiiON FCP LUNZ Disk hdisk4 Defined 05-00-02 EMC CLARiiON FCP LUNZ Disk hdisk5 Defined 05-00-02 EMC CLARiiON FCP LUNZ Disk hdisk6 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk7 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk8 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk9 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk10 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk11 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk12 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk13 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk14 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk15 Defined 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk16 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk17 Available 05-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk18 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk19 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk20 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk21 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk22 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdisk23 Available 07-00-02 EMC CLARiiON FCP RAID 5 Disk hdiskpower0 Available 05-00-02 PowerPath Device hdiskpower1 Available 07-00-02 PowerPath Device hdiskpower2 Available 05-00-02 PowerPath Device
lspv 确定主机中那块内置硬盘没有被VG使用
# lspv hdisk0 0057908c7251c07a rootvg hdisk1 0057908cea9403a2 None hdisk2 005d03fc9859db6c datavg [IBMP740-1:root:/]# lspv hdisk0 00f7ac3dfb20ed5a None hdisk1 00f7ac3d60694e5e rootvg active hdisk10 none None hdisk11 none None hdisk12 none None hdisk13 none None hdisk16 none None hdisk17 none None hdisk18 none None hdisk19 none None hdisk20 none None hdisk21 none None hdisk22 none None hdisk23 none None
lsattr -El 确定hdisk0与hdisk1硬盘的大小一致

lscfg -vpl 确认硬盘的Part number或FRU Number号是否一样，如一样说明硬盘型号一样。

Device Type: block由上可知，hdisk0与hdisk1型号、大小一致，可以做rootvg镜像。
#一般基本上除了haview ，netwiew ( Tivoli)的包以外，所有的hacmp的包都要安装。
1.2 配制rootvg镜像
首先将hdisk1硬盘加入到rootvg中
# extendvg rootvg hdisk1
0516-014 linstallpv: The physical volume appears to belong to another
volume group.
005d027c00004c00
0516-631 extendvg: Warning, all data belonging to physical
volume hdisk1 will be destroyed.
extendvg: Do you wish to continue? y(es) n(o)? y
# lspv
hdisk0 0057908c7251c07a rootvg
hdisk1 0057908cea9403a2 rootvg
hdisk2 005d03fc9859db6c datavg
给rootvg做镜像
# mirrorvg rootvg hdisk1
0516-1124 mirrorvg: Quorum requirement turned off, reboot system for this
to take effect for rootvg.
0516-1126 mirrorvg: rootvg successfully mirrored, user should perform
bosboot of system to initialize boot records. Then, user must modify
bootlist to include: hdisk0 hdisk1.
给hdisk0、hdisk1分别做引导分区
# bosboot -ad hdisk0 bosboot: Boot image is 15092 512 byte blocks. # bosboot -ad hdisk1 bosboot: Boot image is 15092 512 byte blocks.
设定系统的引导顺序为hdisk0、hdisk1
# bootlist -m normal hdisk0 hdisk1 # bootlist -m normal -o hdisk0 blv=hd5 pathid=0 hdisk1 blv=hd5 pathid=0
设定Quorum为Disable.，这样保证了一旦硬盘坏了一块，rootvg还是能正常启来。
# chvg -Qn rootvg 0516-1804 chvg: The quorum change takes effect immediately.
执行lsvg命令确认rootvg已做镜像，可看到除了lg_dumplv之外所有其它LPs和PPs的对应关系为1对2的关系。

2 更换rootvg中的故障盘
这里假设hdisk0硬盘故障，需要更换。
2.1 确定hdisk0硬盘故障
首先执行errpt命令查看错误日志,如果hdisk0损坏的话，会有很多hdisk0的报错。

执行lsvg 确认镜像丢失，可看到LPs和PPs的对应关系变为11对应。

执行lspv -l hdisk0命令会报错，确认hdisk0硬盘故障。
2.2 更换hdisk0硬盘
首先将hdisk0硬盘从rootvg中unmirror
# unmirrorvg rootvg hdisk0 0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run 'chpv -c' as root user to clear the boot record and avoid a potential boot off an old boot image that may reside on the disk from which this logical volume is moved/removed. 0516-1132 unmirrorvg: Quorum requirement turned on, reboot system for this to take effect for rootvg. 0516-1144 unmirrorvg: rootvg successfully unmirrored, user should perform bosboot of system to reinitialize boot records. Then, user must modify bootlist to just include: hdisk1.
执行chpv -c hdisk0命令清除掉boot记录
# chpv -c hdisk0
0301-108 mkboot: Unable to read file blocks. Return code: -1
0516-1248 chpv: mkboot failure
# reducevg rootvg hdisk0
0516-016 ldeletepv: Cannot delete physical volume with allocated
partitions. Use either migratepv to move the partitions or
reducevg with the -d option to delete the partitions.
0516-884 reducevg: Unable to remove physical volume hdisk0.
这是因为 lg_dumplv在rootvg缺省情况下没有做镜像的原因，只创建在hdisk0上,现在要修改主dump目录为null（空目录)
# lslv -l lg_dumplv lg_dumplv:N/A PV COPIES IN BAND DISTRIBUTION hdisk0 008:000:000 100% 000:008:000:000:000 # sysdumpdev -P -p /dev/sysdumpnull primary /dev/sysdumpnull secondary /dev/sysdumpnull copy directory /var/adm/ras forced copy flag TRUE always allow dump FALSE dump compression ON type of dump traditional
从rootvg中删除hdisk0硬盘
# reducevg -d rootvg hdisk0
0516-914 rmlv: Warning, all data belonging to logical volume
lg_dumplv on physical volume hdisk0 will be destroyed.
rmlv: Do you wish to continue? y(es) n(o)? yes
rmlv: Logical volume lg_dumplv is removed.

2.3添加新硬盘到rootvg中,并做镜像
拔出hdisk0故障硬盘，插入新硬盘。执行以下操作将新硬盘加入到rootvg中
# cfgmgr -v
查看磁盘是否有pvid如果没有执行chdev -l hdisk0 -a pv＝yes
# lspv hdisk0 none None hdisk1 00f45bd06cef0cfa rootvg active hdisk2 none None hdisk3 none None hdisk4 none None hdisk5 none None hdisk6 none None hdisk7 none None hdisk8 none None hdisk9 none None hdisk10 none None hdisk11 none None hdiskpower0 none None hdiskpower1 none None hdiskpower2 none None hdiskpower3 none None hdiskpower4 none None hdisk12 none None hdisk13 none None hdisk14 none None hdisk15 none None hdisk16 none None hdisk17 none None hdiskpower5 none None hdiskpower6 none None hdiskpower7 none None hdisk18 none None hdisk19 none None hdisk20 none None hdisk21 none None hdisk22 none None hdisk23 none None hdiskpower8 none None hdiskpower9 none None hdiskpower10 none None # chdev -l hdisk0 -a pv=yes hdisk0 changed # lspv hdisk0 00f45bd0101716a0 None hdisk1 00f45bd06cef0cfa rootvg active hdisk2 none None hdisk3 none None hdisk4 none None hdisk5 none None hdisk6 none None hdisk7 none None hdisk8 none None hdisk9 none None hdisk10 none None hdisk11 none None hdiskpower0 none None hdiskpower1 none None hdiskpower2 none None hdiskpower3 none None hdiskpower4 none None hdisk12 none None hdisk13 none None hdisk14 none None hdisk15 none None hdisk16 none None hdisk17 none None hdiskpower5 none None hdiskpower6 none None hdiskpower7 none None hdisk18 none None hdisk19 none None hdisk20 none None hdisk21 none None hdisk22 none None hdisk23 none None hdiskpower8 none None hdiskpower9 none None hdiskpower10 none None
把hdisk0加入到rootvg

做rootvg镜像
# mirrorvg rootvg hdisk0

创建引导映像
# bosboot -ad hdisk0 bosboot: Boot image is 53276 512 byte blocks. # bosboot -ad hdisk1 bosboot: Boot image is 53276 512 byte blocks.
改变引导区引导顺序
# bootlist -m normal hdisk0 hdisk1
查看引导顺序
