In the 3DC multi-target configuration using delta resync, one journal uses two mirrors. Operation results differ depending on whether or not the specified mirror is for the delta resync.Deleting the pairs in a mirror
When you delete the pairs in a mirror, data copying between master and restore journals ends.
Prerequisite information
This operation can be performed from the primary or secondary system.
When you delete the pairs in a mirror between the intermediate site and the secondary site in a 3DC cascade configuration using 3 UR sites, the mirror status between the primary site and the intermediate site must be Stopped, or the mirror status between the intermediate site and the secondary site must be Stopped.
In the 3DC multi-target configuration using delta resync, one journal uses two mirrors. Operation results differ depending on whether or not the specified mirror is for the delta resync.
When the specified mirror's status is Hold, Holding, or Hold (Failure) (when delta resync mirrors are specified), only the specified mirror's UR pairs are deleted.
When the specified mirror's status is other than Hold, Holding, or Hold(Failure) (when mirrors not for delta resync are specified), delta resync mirror's UR pairs that are not specified are also deleted.
Procedure
Open the Remote Replication window.
In Command Suite: On the Resources tab, expand the Storage Systems tree, right-click the target storage system, and click Remote Replication.
In Device Manager - Storage Navigator: In the Storage Systems tree, click Replication > Remote Replication.
Select the Mirrors tab, and then select the mirrors to be deleted.
From the Actions menu, click Remote Replication > Delete Mirrors.
In the Delete Mirrors dialog box, review the mirrors in the Selected Mirrors table.
For Delete Mode, specify one of the following:
Normal: Mirrors are deleted only if the primary system can change the mirror status to Initial.
Force: Mirrors are forcibly deleted even when the primary system cannot communicate with the secondary system.
Click Finish.
In the Confirm window, review the settings and enter a task name in the Task Name box.
Click Apply to save your settings to the system.
If the journal (mirror) status is not Initial—even though you deleted pairs forcibly and five minutes have passed—perform the operation again to delete all pairs registered to the mirror.
Do not create pairs with the same journal for at least five minutes, even if the journal status was Initial; otherwise pair creation could fail and the pair would be suspended.
