AIX rootvg镜像换盘问题

-m exact map Allows mirroring of logical volumes in the exact physical partition order that the

original copy is ordered. This option requires you to specify a PhysicalVolume(s)

where the exact map copy should be placed. If the space is insufficient for an

exact mapping, then the command will fail. You should add new drives or pick a

different set of drives that will satisfy an exact logical volume mapping of the

entire volume group. The designated disks must be equal to or exceed the size of

the drives which are to be exactly mirrored, regardless of if the entire disk is used.

Also, if any logical volume to be mirrored is already mirrored, this command will

fail

mirrorvg -m rootvg  hdisk1（146G的） hdisk3（300G）的可以么？

或者smit mirrorvg 之后esc+7 选择pv，先选146G，后选300G的试试可以么？

mirrorvg的时候有个参数，-m这个参数，man mirrorvg 看看就明白了！

smitty菜单这么好用，为什么还要去记命令。

哪两个盘同步在smitty mirrorvg里面有选项把需要同步的两个盘选上。

楼上的可行

移除镜像的时候，选下盘就好了。。。。
