Chapter 6 Configuring Journal Groups 6-3
Hitachi Universal Replicator for IBM /OS User’s Guide
Registering Journal Volumes in a Journal Group
To be able to perform remote copy operations with URz, the primary site
administrator must register journal volumes in journal groups in the primary
storage system. Also, the secondary site administrator must register journal
volume in journal groups in the secondary storage system. One journal group
can contain up to 16 journal volumes.
To register journal volumes, follow the procedure below. Both the primary
storage system administrator and the secondary storage system administrator
must perform this 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 Journal Operation window is displayed.
3. In the tree of the Journal Operation window, do either of the following:
– If you want to register new volumes to a journal group in which journal
groups are already registered, select the journal group from below
Registered.
Caution: You can register volumes only when the attribute of the
journal group is Initial or when the status of the journal group is
Active, or Stop, Hold, or Hold(Failure).
– If you want to register volumes to a journal group in which journal
groups have not been registered, select the journal group from below
Free.
Note: You cannot select more than one journal group.
4. Do either of the following:
– In the tree, right-click the selected journal group and then select Edit
JNL Volumes from the pop-up menu.
– In the upper-right list, right-click the desired journal group and then
select Edit JNL Volumes from the pop-up menu.
5. In the Free Volumes list of the Edit JNL Volumes window (
Figure 6-1),
select the volumes that you want to register.
In the Free Volumes list, one row represents one volume. If you cannot
find the volumes that you want to register, do any of the following:
– Select the PG radio button, enter a parity group number in the text
boxes to the right, and then select Show. The list displays volumes in
the specified parity group. Finally, select the volumes that you want to
register.
