AIX在正常开机换roovg一块损害硬盘.doc

更换rootvg里一块坏掉的硬盘rootvg里的hdisk0坏掉，首先解除镜相#unmirrorvg rootvg hdisk0#chpv -c hdisk0 (清除引导区)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.0301-108 mkboot: Unable to read file blocks. Return code: -10516-1132 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.#bootlist -m normal ohdisk0 hdisk1 blv=hd5#lsvg -p rootvgrootvg:PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTIONhdisk0 missing546 482 70.85.109.109.109hdisk1 active 546 254 60.00.00.85.109尝试把hdisk0从rootvg里面删除先查询hdisk0还挂有那些逻辑卷#lspv l hdisk0显示没有挂接逻辑卷#reducevg rootvg hdisk00516-016 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.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_dumplv;第三步：在hdisk1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 hdisk0命令BYD实际情况是：hdisk0有fwdump文件系统 没有做镜像，且里面没有内容，#umount fwdump#smitty rmlv把fwdump文件系统删除hdisk0还有个换页空间paging01 也同样没有做镜像先删除换页空间#smitty swapoff#smitty rmps#lspv l hdisk0删除hdisk0, 更换新硬盘,rmdev dl hdisk0#diag按enter选择Hot Plug Task按下enter键，可以热拔硬盘，把准备好的硬盘换上让操作系统重认hdisk0#cfgmgr v将hdisk0添加到rootvg里面#extendvg rootvg hdisk00516-1254 extendvg: Changing the PVID in the ODM. test_db#lsvg -p rootvgrootvg:PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTIONhdisk0 active546 546 110.109.109.109.109hdisk1 active 546 190 60.00.00.21.109重镜相rootvg,因为只有两块盘，不用指定镜相到哪块盘上#mirrorvg -S rootvg （后台同步）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. 查看当前的引导列表信息：#bootlist -m normal -ohdisk0hdisk1在hdisk0制作引导信息#bosboot -ad hdisk0bosboot: Boot image is 21175 512 byte blocks.重新在hdisk1上制作引导信息#bosboot -ad hdisk1bosboot: Bo
