ETERNUS SF AdvancedCopy Manager 14.2 Operator's Guide

4.2.2 Selecting a backup source

The backup/restoration unit of the HP-UX AdvancedCopy Manager is a physical disk (LU: Logical Unit). However, in the case of a physical disk which constitutes the LVM (Logical Volume Manager), it is managed and operated as a volume group. This disk is called a transaction volume (source).

A transaction volume to be backed up must reside on the ETERNUS disk storage systems.

For information on setting up a transaction volume, see "4.4.7 Setting the operation type for a device".
