To create the XP Continuous Access Journal pair for delta resync operations, specify the XP
Continuous Access Synchronous S-VOL in the XP Continuous Access Synchronous secondary
site as the primary XP Continuous Access Journal delta resync data volume, and specify the
XP Continuous Access Journal delta resync secondary data volume in the XP Continuous Access
Journal secondary site as the secondary data volume. For instance, execute the "Paircreate
–f async … -nocsus" raid managed command from the DC2 and DC3 sites in order to create
the suspended journal pair.
Select any mirror ID from 1 to 3, except the one used in step 4.
NOTE:
If you delete the XP Continuous Access Synchronous pair created in step 2, the XP
Continuous Access Journal delta resync contingency pair created in step 6 is deleted as well.
In addition, if you delete the XP Continuous Access Journal pair created in step 6, the secondary
data volume of the XP Continuous Access Journal pair created in step 6 is deleted. In this
case, you can only perform the delete operation on the remaining primary data volume.
For more information about installing and using XP Continuous Access Synchronous, see the
HP StorageWorks XP Continuous Access user guide for the XP12000/XP10000/SVS200.

Requirements for creating XP Continuous Access Journal pairs for delta resync operations
To create an XP Continuous Access Journal pair for delta resync operations, the following are
required:
•
Create the pair in a 3DC multi-target configuration.
•
Use the XP Continuous Access Synchronous S-VOL in PAIR status as the delta resync contingency
primary data volume.
•
Use the XP Continuous Access Journal data volume in PAIR status as the delta resync
contingency secondary data volume.
•
Use the mirror ID from 1 to 3 that is not used by the secondary data volume.
•
Fulfill the conditions to combine XP Continuous Access Journal with other functions in
.
•
The system option mode 506 must be set to ON at all sites
In addition to these requirements, all XP Continuous Access Journal pairs in the journal group must
satisfy the following requirements when creating more than one XP Continuous Access Journal pair
for delta resync operation.
•
Use the same mirror ID for all pairs.
•
Use the same restore journal group for all pairs.
Requirements for performing delta resync operations
To perform delta resync operations properly, you must specify an XP Continuous Access Journal
pair that belongs to the journal group whose XP Continuous Access Journal pairs meet the following
requirements. If any XP Continuous Access Journal pair in the journal group does not meet the
requirements, an error occurs even if the specified XP Continuous Access Journal pair meets the
requirements.
•
Primary data volume's status is HOLD.
•
Use the XP Continuous Access Synchronous pair's secondary volume as the delta resync
contingency primary data volume.
If you use the XP Continuous Access Synchronous P-VOL, the pair status should be PAIR.
