	ES222:chapter22-Top-Down volume creation(overview)
	<p>创建top-down卷可以用来帮助使用metassist命令自动创建solaris卷管理器的配置，这样就不用手动的进行磁盘分区、创建RAID-0卷、创建热插拔组件、创建镜像等操作.相反的，可以只用metassist命令创建一个卷，剩下的工作则由solaris卷管理器来完成 </p><p>The metassist command enables you to create solaris volume manager volume configurations with a single command. You can specify volume characteristics in terms of quality-of-service. Quality-of-service characteristics means that without specifying the hardware com……
