After you stop the partnership, your partnership is listed as Fully Configured: Stopped, as
shown in Figure 10-93.
Figure 10-93 Fully configured partnership in Stopped state
You can restart a stopped partnership by clicking Start Partnership from the Actions
The partnership returns to the fully configured status when it is restarted.
Deleting a partnership
You can delete a partnership by selecting Delete Partnership from the Actions drop-down
menu, as shown in Figure 10-92 on page 521.
10.4.2 Managing stand-alone Remote Copy relationships
A Remote Copy relationship can be defined between two volumes where one is the master
(source) and the other one is the auxiliary (target) volume. Use of Remote Copy auxiliary
volumes as Remote Copy master volumes is not allowed. Open the Remote Copy window to
manage Remote Copy by clicking the Copy Services icon and then clicking Remote Copy,
as shown in Figure 10-94 on page 523.

The Remote Copy window displays a list of Remote Copy consistency groups. You can also
take actions on the Remote Copy relationships and Remote Copy consistency groups. Click
Not in a Group and all the Remote Copy relationships that are not in any Remote Copy
consistency groups are displayed. To customize the blue column heading bar and select
different attributes of Remote copy relationships, right-click anywhere in the blue bar.
Creating stand-alone Remote Copy relationships
To create a Remote Copy relationship, click New Relationship at the top of the Remote Copy
window, as shown in Figure 10-95 on page 523. A wizard opens and guides you through the
Remote Copy relationship creation process.
As shown in Figure 10-96, you must set the Remote Copy relationship type first. Based on
your requirements, you can select Metro Mirror (synchronous replication) or Global Mirror
(asynchronous replication). Select the appropriate replication type and click Next.
Figure 10-96 Select the appropriate Remote Copy type
Important: Before a remote copy relationship is created, target volumes that are the same
size as the source volumes that you want to mirror must be created. For more information
about creating volumes, see Chapter 5, “I/O Group basic volume configuration” on
Chapter 10. Copy services 525
You must select where your auxiliary (target) volumes are: the local system or the already
defined second storage system. In our example (as shown in Figure 10-97), choose another
system to build an inter-cluster relationship. Click Next to continue.
Figure 10-97 Select Remote Copy partner
The Remote Copy master and auxiliary volume must be specified. Both volumes must have
the same size. As shown in Figure 10-98, the system offers only appropriate auxiliary
candidates with the same volume size as the selected master volume. After you select the
volumes that are based on your requirement, click Add.

You can define multiple and independent relationships by clicking Add. You can remove a
relationship by clicking the red cross. In our example, we create two independent Remote
Copy relationships, as shown in Figure 10-99.
Figure 10-99 Define multiple independent relationships
A window opens and prompts you to select if the volumes in the relationship are already
synchronized. In most situations, the data on the master volume and on the auxiliary volume
are not identical, so click No and then click Next to enable an initial copy, as shown in
