Configuring Logical Volume Storage

With Logical Volume Storage you can mirror volume groups, define a logical volume, and remove a disk with the system running.

Mirroring a volume group
These scenarios explain how to mirror a normal volume group.
Mirroring the root volume group
The following scenario explains how to mirror the root volume group (rootvg).
Defining a raw logical volume for an application
A raw logical volume is an area of physical and logical disk space that is under the direct control of an application, such as a database or a partition, rather than under the direct control of the operating system or a file system.
Unmirroring the root volume group
You can unmirror the root volume group.
Removing a disk while the system remains available
The following procedure describes how to remove a disk using the hot-removability feature, which lets you remove the disk without turning the system off. This feature is only available on certain systems.
