HP StorageWorks
P9000 Continuous Access Synchronous User
Guide
Abstract
This guide explains how to use HP StorageWorks XP P9000 Continuous Access Synchronous Software to protect information
stored on HP StorageWorks P9000 disk arrays from local disaster by continuously copying local data across Fibre Channel
connections to remote HP StorageWorks P9000 disk arrays. Topics include configuring and managing remote copies using
Remote Web Console, recovering from a disaster, troubleshooting, and using Continuous Access for data migration and
point-in-time replication. The intended audience is a storage system administrator or authorized service provider with independent
knowledge of HP StorageWorks P9000 disk arrays and Remote Web Console.
