Overview of AIX® logical volume manager
The logical volume manager (LVM) software provides complete control over all disks and file systems. LVM also migrates data at a single logical volume level, a physical volume (DDM) level, or entire contents of a volume group.
The primary tasks for migrating data with the LVM use commands
that affect the following functions:
- Copying
- Mirroring
- Migrating
You can also use the direct copy method to migrate data. While this method uses the LVM, its main focus is on the use of the UNIX find and cpio commands.
