If you're trying to determine why a server won't boot after a disk failure, the first thing I often do is to un-map or disconnect all disks from the server except for the root volume group.

如果想要判断一个服务器为何在磁盘故障后不能引导，我通常会做的第一件事情是从服务器(根卷组除外)，断开所有磁盘的映射和连接。

As a pre-cautionary measure, we verify that rootvg is now mirrored, include the new disk in the boot list and create a new boot image for the mirrored volume group.

作为一种预先的防范措施，我们验证了 rootvg 现已被镜像、在引导列表中包含了新磁盘并为所镜像的卷组创建了新的引导映像。
