With these changes finished, you should be able to extend the logical volumes in your volume group, as described shortly.
完成这些修改之后，您就可以在您的卷组中扩展逻辑卷了，正如之前描述的。

如果将逻辑卷复制到空的卷组，就会出现这种情况。
This command mirrors all the logical volumes that exist on a given volume group (see Listing 12).
该命令镜像给定卷组中存在的所有逻辑卷(请参见清单12)。
And a volume group can be logically partitioned into logical volumes.
卷组可以在逻辑上划分成多个逻辑卷。
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.
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。
Logical volume will be defined per volume group on one log; however, multiples might be defined.
为一个日志中的每个卷组定义逻辑卷；然而，可以定义多个逻辑卷。
So after the assignment of PVs to the volume group, you can create a logical volume of any size (to the maximum of the VG size).
在将PV分配给卷组之后，就可以创建任意大小的逻辑卷(只要不超过VG的大小)。
This also makes the volume group active and updates the new LPAR with details of file systems associated with the logical volumes.
这样还可以激活卷组，并用逻辑卷组相关联的文件系统的细节信息来更新新的LPAR。
Using the resource group name to define a logical volume name, determine which volume group and resource group this logical volume belongs to.
使用资源组名定义一个逻辑卷名，确定这个逻辑卷属于哪个卷组和资源组。
Each logical volume is associated with a volume group, and each volume group typically contains several logical volumes.
每个逻辑卷都关联于一个卷组，并且每个卷组通常包含几个逻辑卷。
Figure 14 shows the logical volume, physical volume, file system, and volume group.
图14显示逻辑卷、它的物理卷、文件系统和卷组。
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.
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。
You can add a volume group or add logical volumes.
可以添加卷组或添加逻辑卷。
In our case we created the logical volumes per volume group.
本例中，每个卷组都创建了逻辑卷。
The logical volume name should also be based upon the previously defined resource group name.
逻辑卷名也应该基于前面定义的资源组名。
To do that, the logical volumes belonging to that volume group must be closed.
在此之前，必须关闭属于此卷组的逻辑卷。
Let's look first at a volume group and find the logical volumes that are a part of it.
让我们首先看一下卷组并查找其中的逻辑卷。
When the logical volumes are closed, you should be able to deactivate the volume group.
关闭逻辑卷后，就能够停用卷组。
This method requires assigning a disk to a VIO server and using the padmin user ID to create a volume group and logical volumes (LVs) on that disk.
这种方法需要把磁盘分配给VIO服务器，然后使用padmin用户ID在这个磁盘上创建卷组和逻辑卷(LV)。
Next, we create logical volumes in the volume group "HBVG".
接下来，在卷组“hbvg ”中创建逻辑卷。
How do I display all logical volumes that are part of a volume group (for example, rootvg)?
如何显示属于某个卷组(例如，rootvg)的所有逻辑卷？
Finally, you actually tuned your logical volumes by determining and increasing the amount of pbufs used in a specific volume group.
最后，通过确定和增加特定卷组所使用的pbuf数量，对逻辑卷进行了优化。
Copying a logical volume to a different volume group.
将逻辑卷复制到另一个卷组。
Login with Admin1 user and able to create logical volumes under VG1 volume group.
以admin1用户登录，可在VG 1卷组下创建逻辑卷。
Let's look at how to copy a logical volume to a different volume group. The steps involved are.
我们来看看如何将逻辑卷复制到另一个卷组。
Logical volume management is a disk abstraction layer that allows you to group physical disks into a single entity called a volume group.
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(volume group)的单一实体。
As an example, a resource group named db2apmx0 might have a volume group named db2apmx00vg. This volume group has multiple JFS log logical volumes associated with it.
作为一个示例，名为db2apmx0的资源组可能拥有一个名为db2apmx00 vg的卷组。
However, we can't mount or create filesystems on a volume group directly. Instead, we can tell LVM to create one or more "logical volumes" using our volume group storage pool.
不过，我们不能直接在卷组上安装或创建文件系统。
These need to be changed as the logical volume now resides in the volume group apps_vg with different log and dev values. To reflect where the log and logical volume now resides, change the following
因为这个逻辑卷现在位于卷组 apps_vg 中，所以需要修改log和dev值。
