Creating a Pair of Data Volumes
Using the Add Pair window, the administrator of the primary storage system
must create pairs of a primary data volume and a secondary data volume.
When creating a pair, the administrator can specify options for initial copy
activities.
Before creating one or more pairs, the administrator must make sure that:
•
The volumes to be used as secondary data volumes are offline to all hosts.
•
Ports have already been configured (see section Configuring Port
Attributes)
•
The primary storage system is associated with the secondary storage
system (see section Establishing the Relationship between Primary and
Secondary Storage Systems (Add DKC))
After all these points are confirmed, the administrator of the primary storage
system can follow the procedure below to create a pair of a primary data
volume and a secondary data volume. Note that the administrator of the
secondary storage system cannot perform the following operation.
1. Ensure that the Storage Navigator main window is in Modify mode.
For detailed information about how to do this, please refer to Storage
Navigator User’s Guide.
2. Ensure that the Pair Operation window is displayed.
3. In the tree, select a CU image number.
4. In the list, select and right-click the volume that you want to use as a
primary data volume.
Notes:
–
Volumes with the icon are already used as primary data volumes.
–
You can select and right-click more than one volume if you want to
create more than one pair at one time. Note that you will need to
choose all the secondary data volumes from the same secondary
storage system.
5. From the pop-up menu, select Add Pair.
The Add Pair window appears (Figure 8-2).
6. In DKC, specify the secondary storage system.
7. In S-VOL, specify the secondary data volume.
