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 mirror in Hold 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 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 (see section Journal
Operation Window).
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 mirrors that are in Stop, Hold, or Hold(Failure) status.
5. From the mirrors, select and right-click the mirror(s) that you want to
restore.
When you select the mirror in Stop status, the copying of data will be
restarted after the recovery.
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 will be
restarted after the recovery.
– When you select the mirror in Hold status, delta resync operation will
be performed after the recovery.
– When you select the mirror in Hold(Failure) status, the status will
change 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.
– If you want 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. Select Apply to restore the mirror(s).
