Creating a persistent FlashCopy relationship

Complete this task to create a persistent FlashCopy^® relationship that remains even after the FlashCopy operation completes.

Creating a persistent FlashCopy relationship prevents another FlashCopy task from writing to your target volume before you have deleted the FlashCopy relationship.

You can perform this task using either the DS CLI or the DS Storage Manager.

Perform the following steps to create a persistent FlashCopy relationship between a source volume and target volume.

In the navigation, select Real-time Manager > Copy Services > FlashCopy.
Select Create... from the Select Action drop-down menu, and click Go. All storage complexes that are listed in the drop-down list are based on the storage complexes that you added during the configuration process. You can change which storage complex or resource type from which to select volumes. All relationships that are displayed can be source or target volumes from the selected domains.
Select the type of relationship to create (single source volume with a single target or single source volume with multiple target volumes), and click Next.
On the Select source volumes page, select the source volumes for the FlashCopy relationships, and click Next.
On the Select target volumes page, select your target volumes and click Next.
After you have selected your target volumes, click Next.
On the Select common options page, select the Make relationships persistent option, and click Next. Optionally, you can click the following options:
- Initiate background copy copies all tracks from the source to the target volume as a background task.
- Enable change recording and Make relationship persistent allow a relationship to be refreshed later. If you click Enable change recording, Make relationship persistent is automatically selected.
- The Permit FlashCopy to occur if target volume is online for host access allows the target volume to be online for host system access. This parameter applies only to count key data volumes.
- Establish target on existing Metro Mirror source allows the FlashCopy target volume to be a remote mirror and copy source volume.
- Sequence number for these relationships is used for Global Mirror functions.
On the Verification page, review the attributes and values that you selected to verify that they are correct.
If the attributes and values are not correct, click Back to return through the selections, and specify the correct values. Otherwise, click Finish to complete the FlashCopy relationship task.
