问题若超出了文件系统的范畴时，通常会转向卷组级别。
When the problem exceeds the file system realm, it often goes to the volume group level.
您可以以一种常见的方式从UNIX文件系统目录安装卷。
You can mount a volume in a manner familiar from a UNIX file system directory.
如果必须使用这样的文件系统，可能有必要使用多个卷。

从aix早期开始，LVM就已经让磁盘、逻辑卷和文件系统的管理变得很轻松。
From the earliest days of AIX, the LVM has made management of disks, logical volumes, and file systems easy.
在目标LPAR上配置磁盘、卷组和文件系统。
Configure the disks, volume group, and file systems on the target LPAR.
这确保数据卷组和文件系统是一致的。
This ensures that the data volume groups and the file systems are consistent.
向目标LPAR分配磁盘之后，需要在操作系统层识别它们并让卷组和文件系统能够使用。
After you assign the disks to the target LPAR, you need to identify them at the operating system level and then make the volume group and file systems available.
这需要卸载属于将要导出卷组的文件系统。
That requires you to unmount the file systems that belong to the volume group you are going to export.
因为他们将数据库数据映射到底层物理存储(原始磁盘、文件系统、卷)，在一个新的平台中理解它们对于dba来说很重要。
Because they map database data to underlying physical storage (raw disks, file systems, volumes), understanding them in a new platform is critical for DBAs.
创建分区、逻辑卷和文件系统。
确保此文件系统和卷组(例如，rootvg)有足够的空间可用。
Ensure that this file system and the volume group (for example, rootvg) has adequate space available.
列出卷组中的文件系统。
有几种系统问题可能影响文件系统，使用多个卷有助于缓解它们的影响
