HP StorageWorks
P9000 Continuous Access Journal User
Guide
Abstract
This guide explains how to use HP StorageWorks P9000 Continuous Access Journal Software to replicate data between local
and remote HP StorageWorks P9000 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 HP StorageWorks P9000 disk arrays and the HP StorageWorks Remote Web Console.
