rootvg移除坏盘的方法

1、rootvg里的hdiskO坏掉，首先解除镜相 test_db#unmirrorvg rootvg hdiskO0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run chpv -c as root user to clear the boot record and avoid a potential bootoff an old boot image that may reside on the disk from which thislogical volume is moved/removed.0301-108

2、mkboot: Unable to read file blocks. Return code: -10516-1132 unmirrorvg: Quorum requirement turned on, reboot system for thisto take effect for rootvg.0516-1144 unmirrorvg: rootvg successfully unmirrored, user should performbosboot of system to reinitialize boot records. Then, user must modify bootl

3、ist to just include:hdisk1.test_db#test_db#test_db#test_db#lsvg -p rootvgrootvg:PV_NAMEPV STATETOTAL PPshdisk0missing546482hdisk1active546254FREE PPs FREE DISTRIBUTION70.85.109.109.10960.00.00.85.109尝试把hdisk0从rootvg里面删除test_db#reducevg rootvg hdisk00516-016 ldeletepv: Cannot delete physical volume w

4、ith allocatedpartitions. Use either migratepv to move the partitions orreducevg with the -d option to delete the partitions.0516-884 reducevg: Unable to remove physical volume hdisk0.报这个错的原因是因为lv_dumplv只存在于hdisk0,而且这个在rootvg里面是不会镜相的，只有一份。后来想到一个办法:第一步：将 dump 设备指向 /dev/sysdumpnull ； 第二步：删除在disk0上lg_du

5、mplv;第三步：在hdiskl上创建新的lg_dumplv;第四步：将 dump设备指向/dev/lg_dumplv最后成功执行reducevg rootvg hdiskO 命令，删除hdiskO,更换新硬盘，让操作系统重认hdiskO 将hdiskO添加到rootvg里面test_db#extendvg rootvg hdiskO0516-1254 extendvg: Changing the PVID in the ODM.test_db#lsvg -p rootvg rootvg:PV_NAMEPV STATETOTAL PPs FREE PPs FREE DISTRIBUTIONhd

6、isk0active546546110.109.109.109.109hdisk1active54619060.00.00.21.109重镜相rootvg,因为只有两块盘，不用指定镜相到哪块盘上test_db#mirrorvg rootvg0516-1124 mirrorvg: Quorum requirement turned off, reboot system for thisto take effect for rootvg.0516-1126 mirrorvg: rootvg successfully mirrored, user should performbosboot of s

7、ystem to initialize boot records. Then, user must modify bootlist to include: hdisk0 hdisk1.查看当前的引导列表信息：test_db#bootlist -m normal -ohdisk0hdisk1在hdisk0制作引导信息test_db#bosboot -ad hdisk0bosboot: Boot image is 21175 512 byte blocks.重新在hdisk1上制作引导信息test_db#bosboot -ad hdisk1 bosboot: Boot image is 21175 512 byte b
