Restoring a Mirror (Resuming a Copy Operation)
A mirror is a combination of a master journal group and a restore journal group. If you split a
mirror, the copying of data from the master journal group to the restore journal group will be
suspended. To restart the copying of data, you need to restore the mirror. As for a mirror in Hold
or Holding status, you need to restore the mirror in order to restart the copying of data.
To restore a mirror, follow the procedure below. Only the primary storage system administrator
can perform this operation; the secondary storage system administrator cannot perform this
operation.
1. Ensure that the Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the HP XP24000/XP20000 Remote Web
Console User's Guide.
2. Ensure that the Journal Operation window is displayed (see “Journal Operation Window”
(page 108) ).
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
from the list to the right.
The list displays a list of mirrors. One row in the list represents one mirror.
4. Locate the mirrors that are in Stop, Hold, Holding, or Hold(Failure) status.
5. From the mirrors, select and right-click the mirror(s) that you want to restore.
The result of this operation differs according to the status of the selected mirror.
•
When you select the mirror in Stop status, the copying of data is restarted after the
recovery.
•
When you select the mirror in Hold or Holding status, the delta resync operation is
performed after the recovery.
•
When you select the mirror in Hold(Failure) status, the status changes to Hold after the
recovery.
6. From the pop-up menu, select JNL Groups and Resume Pair.
7. See the Preview list to check the mirrors that you want to restore.
•
To cancel restoring a mirror, select and right-click the mirror and then select Cancel.
•
If necessary, you can repeat steps 3 to 7 to specify other mirrors.
8. Click Apply to restore the mirror(s).
NOTE: If an error occurs, the right-most 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

When one journal group uses two mirror IDs, the result of the operation differs as follows according
to the status of the specified mirror.
