HP XP Continuous Access Software - Manual (Page 72)

The following hardware configuration is required for the local array at these sites:
•
Local array at the primary site
XP Continuous Access Synchronous installed ◦
◦ XP Continuous Access Journal installed
◦ Volume used as an XP Continuous Access Synchronous primary volume and as an XP
Continuous Access Journal primary data volume
◦ XP Continuous Access Journal master journal volume
•
Local array at the XP Continuous Access Synchronous secondary site
XP Continuous Access Synchronous installed ◦
◦ XP Continuous Access Journal installed
◦ XP Continuous Access Synchronous secondary volume
NOTE: This volume might be used as an XP Continuous Access Journal primary data
volume when performing disaster recovery at the primary site. For more information, see
Recovering from primary site failures .
◦ XP Continuous Access Journal master journal volume
NOTE: This volume might be required to create an XP Continuous Access Journal pair
when performing disaster recovery at the primary site or when creating an XP Continuous
Access Journal pair for delta resync operations. For more information, see
Recovering
from primary site failures .
•
Local array at the XP Continuous Access Journal secondary site
XP Continuous Access Journal installed ◦
◦ XP Continuous Access Journal secondary data volume
◦ XP Continuous Access Journal restore journal volume
Setup procedure
This section explains the procedure for setting up a 3DC multi-target configuration using XP
Continuous Access Synchronous and XP Continuous Access Journal.
1. Install XP Continuous Access Synchronous and XP Continuous Access Journal. Configure ports
and journal groups. Journal groups must be configured for arrays at the three sites.
2. At the primary site, create an XP Continuous Access Synchronous pair.
3. Wait until the status of the XP Continuous Access Synchronous pair becomes PAIR.
4. At the primary site, create an XP Continuous Access Journal pair.
When creating an XP Continuous Access Journal pair, select a value from 1 to 3 as the mirror
ID.
5. Wait until the status of the XP Continuous Access Journal pair becomes PAIR. To create an XP
Continuous Access Journal pair for delta resync operations, continue with step 6.
