SnapDrive for UNIX storage commands provision LVM entities by creating LVM objects.
If you request a SnapDrive for UNIX storage operation that provisions an LVM entity—for example, a disk group that includes host volumes or file systems—the snapdrive storage command works with the LVM to create the LVM objects and file systems that use the storage.
The storage is then divided into logical volumes, which are used as if they were raw disk devices to hold file systems or raw data.
Because the data from any specified host volume can be distributed across all disks in the disk group, Snapshot copies can be made and restored only for whole disk groups.
