When replacing the target volume, you must either break the mirror or delete the mirror in order to ensure a full resync of the data from the source volume to the target volume when the target volume is back in place. Though similar to the Pause and Unlock, breaking the mirror marks all bits in the DataKeeper Intent Log as dirty which forces a full resync to occur. Deleting the mirror discontinues replication altogether removing the mirror from the job so that when your mirror is recreated with the new target, a full resync will be performed.

Using the BREAK Command

1. Select the mirror that contains the target you want to replace.

2. Right-click on the mirror and choose Break Mirror or select Break Mirror from the Actions task pane.

3. Select Yes to break the mirror.

4. Once new target is in place, right-click on the job that contains the replaced volume and choose Resync All Mirrors.
5. The target volume will be locked, a full resync will be performed and the mirroring process is resumed.

Using the DELETE Command

1. Select the mirror that contains the target you want to replace.

2. Right-click on the mirror and choose Delete Mirror or select Delete Mirror from the Actions task pane.

3. Select Yes to delete the mirror.

4. Once new target is in place, recreate the mirror.
