rootvg移除壞盤的方法

1、rootvg里的hdiskO壞掉，首先解除鏡相 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嘗試把hdisk0從rootvg里面刪除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.報(bào)這個(gè)錯(cuò)的原因是因?yàn)閘v_dumplv只存在于hdisk0,而且這個(gè)在rootvg里面是不會(huì)鏡相的，只有一份。后來想到一個(gè)辦法:第一步：將 dump 設(shè)備指向 /dev/sysdumpnull ； 第二步：刪除在disk0上lg_du

5、mplv;第三步：在hdiskl上創(chuàng)建新的lg_dumplv;第四步：將 dump設(shè)備指向/dev/lg_dumplv最后成功執(zhí)行reducevg rootvg hdiskO 命令，刪除hdiskO,更換新硬盤，讓操作系統(tǒng)重認(rèn)hdiskO 將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

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