Journal Software User Guide
Abstract
This guide explains how to use HP StorageWorks XP Continuous Access Journal Software to replicate data between local and
remote HP StorageWorks XP disk arrays and to achieve disaster tolerance with maximum application performance. Topics
include setting up remote copy connections, configuring the storage system, creating and monitoring remote copies, recovering
from a disaster, and troubleshooting. The intended audience is a storage system administrator or authorized service provider
with independent knowledge of XP storage systems and Remote Web Console.
