rmdev -dl hdisk 会删除盘上的数据吗？
我做过实验了, testvg里包含两块盘, hdisk1,hdisk2.用exportvg 正确的,用其他办法删除hdisk1,都必须执行reducevg 命令,而只要执行这个命令就会得到数据将被删掉的提示,正确的做法如下(testvg 只有hdisk1,也一样):
1.varyoffvg testvg
2.exportvg testvg
3.rmdev -l hdisk1
4.cfgmgr
5.importvg -y testvg hdisk1
6.lspv -l hdisk1
发现原盘里的东西都在.
能用lspv -l hdisk1看看里面有没有LV吗？
现在的解决办法从ODM数据库中直接删除与datavg2有关的信息：
#odmdelete -o CuDv -q name=datavg2
#odmdelete -o CuAt -q name=datavg2
