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 diskname??????? 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: -1 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. #bootlist -m normal –o hdisk0 hdisk1 blv=hd5 #lsvg -p rootvg rootvg:PV_NAME?????????? PV STATE????????? TOTAL PPs?? FREE PPs???

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smitty swapoff #smitty rmps #lspv –l hdisk0 删除hdisk0, 更换新硬盘,–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–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??????????
