-O 对目标 altinst_rootvg 执行设备重置。这将导致备用磁盘安装不会保留任何用户定义的设备配置。如果目标磁盘变为另一个系统的 rootvg(如逻辑分区或系统磁盘交换的情况),那么这个标记就会派上用场。
原文是:
-O
Performs a device reset on the target altinst_rootvg. This causes the alternate disk install to not retain any user-defined device configurations. This flag is useful if the target
disk or disks become the rootvg of a different system (such as in the case of logical partitioning or system disk swap).
