Continuous Access XP Journal user guide 69
Hardware configurations
A 3DC multi-target configuration requires the following sites:
• Primary site for Continuous Access XP Synchronous and Continuous Access XP Journal
• Secondary site for Continuous Access XP Synchronous
• Secondary site for Continuous Access XP Journal
Each site requires one local array. For Command View XP, a management station is also required.
HP recommends installing RAID Manager XP in the host computers at each site.
The following hardware configuration is required for the local array at these sites:
• Local array at the primary site
• Continuous Access XP Synchronous installed
• Continuous Access XP Journal installed
• Volume used as a Continuous Access XP Synchronous primary volume and as a Continuous Access
XP Journal primary data volume
• Continuous Access XP Journal master journal volume
• Local array at the Continuous Access XP Synchronous secondary site
• Continuous Access XP Synchronous installed
• Continuous Access XP Journal installed
• Continuous Access XP Synchronous secondary volume
NOTE: This volume might be used as a Continuous Access XP Journal primary data volume when
performing disaster recovery at the primary site. For more information, see ”Recovering from
primary site failures” on page 70.
• Continuous Access XP Journal master journal volume
NOTE: This volume might be required to create a Continuous Access XP Journal pair when
performing disaster recovery at the primary site. For more information, see ”Recovering from
primary site failures” on page 70.
• Local array at the Continuous Access XP Journal secondary site
• Continuous Access XP Journal installed
• Continuous Access XP Journal secondary data volume
• Continuous Access XP Journal restore journal volume
Setup procedure
This section explains the procedure for setting up a 3DC multi-target configuration using Continuous
Access XP Synchronous and Continuous Access XP Journal.
1. Install Continuous Access XP Synchronous and Continuous Access XP Journal. Configure ports and
journal groups. Journal groups must be configured for arrays at the three sites.
2. At the primary site, create a Continuous Access XP Synchronous pair.
3. Wait until the status of the Continuous Access XP Synchronous pair becomes PAIR.
4. At the primary site, create a Continuous Access XP Journal pair.
When creating a Continuous Access XP Journal pair, select a value from 1 to 3 as the mirror ID.
5. Wait until the status of the Continuous Access XP Journal pair becomes PAIR.
For more information about installing and using Continuous Access XP Synchronous, see the
HP StorageWorks Continuous Access XP user guide for the XP12000/XP10000/SVS200.
