Hitachi Universal Replicator for IBM /OS User’s Guide
Deleting Data Volumes from a Mirror (Ending a copy
operation)
A mirror is a combination of a master journal group and a restore journal
group. If you delete data volumes (i.e., the primary data volume and the
secondary data volume) from a mirror, the copying of data from the master
journal group to the restore journal group will end.
To delete data volumes from a mirror, follow the procedure below. Not only
the primary storage system administrator but also the secondary storage
system administrator can 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. Do either of the following:
– In the tree, select a master journal group ( ) or a restore journal group
(
) from below Registered.
– In the tree, select Journal Groups or Registered and then select a
master journal group (
) or a restore journal group ( ) from the list to
the right.
The list displays a list of mirrors. One row in the list represents one mirror.
4. Locate mirrors that are not in Initial status.
5. From the mirrors, select and right-click the mirror(s) from which you want
to delete data volumes.
6. From the pop-up menu, select JNL Groups and Delete Pair.
7. See the Preview list to check the settings that you have made.
– If you want to cancel a setting, select and right-click the setting and
then select Cancel.
– If necessary, you can repeat steps 3 to 7 to specify other mirrors.
8. Select Apply to delete data volumes from the mirror(s).
Note: If an error occurs, the rightmost column of the Preview list displays
the error code. To view detailed information about the error, right-click the
error code and then select Error Detail. An error message appears and gives
you detailed information about the error.
