It groups one or more physical volumes (disks) into a 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。
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.
可用接管目标必须确保一个独占、所有权型的资源(例如磁盘组，卷或文件系统)联线。
The potential takeover target must actually bring resources online that are typically an exclusive, ownership-type item, such as disk groups, volume, or file systems.
如前所述，在本例的设置中，每个DS4500只有一个组，包含两个存储节点，两节点间的所有在DS4500上的磁盘都将被twin tailed。
As already described, in this setup there is only one group per DS4500, containing the two storage nodes between which all disks on that DS4500 will be twin tailed.
这个磁盘已经被分配给了现有的一个卷组(rootvg)。
This disk has been allocated to an existing volume group (rootvg).
注意：之所以在mkpprcpath命令内使用了一致性组选项是为了确保跨所有被镜像的磁盘有一个一致的单时间点副本。
Note that the consistency group option is used in the mkpprcpath command to ensure a consistent point-in-time copy across all disks that are being mirrored.
逻辑卷管理是一个磁盘抽象层，它可以将多个物理磁盘分组成称为卷组(volumegroup)的单一实体。
Logical volume management is a disk abstraction layer that allows you to group physical disks into a single entity called a volume group.
存储在磁盘上的每个文件都有一个所有者和一个组，尽管用户和组的实际名称不存储在磁盘上。
Each file stored on disk has an owner and a group, however the actual names of the user and group are not stored on disk.
如果一个卷组满了，那么可以在其中添加另一个物理磁盘，从而创建一个新的逻辑卷或者扩大现有的逻辑卷。
If a volume group becomes full, another physical disk can be added to it to create a new logical volume or enlarge a preexisting logical volume.
选择客户端主机(将要更新的服务器)，输入将要应用tl的磁盘—因为它将会成为一个备用磁盘，要保证这个磁盘没有被任何其他卷组(VG)使用。
Select the client machine (server to be updated), type the disk which the TL will be applied-since this is going to be a alternate disk, make sure the disk is not used by any other volume group (VG).
这些磁盘收集在一个组中，称作卷组。
These disks are collected in a group, called the volume group.
假设出现了以下情况：一个卷组包含两个80gb的磁盘，希望将它们替换为160gb的磁盘。
Imagine the following situation: you have a volume group with two 80gb disks, and you want to upgrade those to 160gb disks.
在LVM配置中，一个或多个分区，或者甚至是整个磁盘，被分配为卷组中的物理卷，卷组转而分成逻辑卷。
In an LVM configuration, one or more partitions, or occasionally entire disks, are assigned as physical volumes in a volume group, which in turn is broken down into logical volumes.
每个AIX系统都有一个rootvg，它是一个卷组，即在安装AIX时所创建的逻辑磁盘组，它包含了AIX操作系统及其标准文件系统。
It's a volume group-a logical group of disks-that is created at the time you install AIX. It contains the AIX operating system with its standard file systems.
用于第一个实例的磁盘物理名称是pdisk10，它在服务器HADB1和HADB2上将分配卷组vga以及逻辑名hdisk16。
The disk has the physical name pdisk10 for the first instance, which will be assigned the volume groups vgA, and a logical name hdisk16 on servers HADB1 and HADB2.
由stripe宽度确定的一组磁盘，将被看作一个stripedcolumn。
One set of disks, as determined by the stripe width, is considered as one striped column.
理论上说，日志文件组的成员的存放位置应该放在磁盘上的不同位置，这样即使一个磁盘损坏也不会导致整个在线重做日志文件丢失。
Ideally, the locations of the members should be on separate disks so that the failure of one disk does not cause the loss of the entire online redo log.
