Administrator Guide

• Manual — Select Manual and click Next to define the properties for the replication repository. Then click Finish.
NOTE: The replication repository is normally created automatically during virtual disk pair creation. Manual
repository creation is recommended only for advanced storage administrators who understand physical disk
consistency and optimal physical disk configurations. The Automatic method is recommended.
6. Click OK when you see a message that the pair is successfully created.
Creating replicated pairs on the remote storage array
1. In the AMW of the local storage array, select the Storage & Copy Services tab.
2. Select Copy Services > Remote Replication > Remote Replication > Replication Group > Complete Replication Pair.
The Complete Remote Replicated Pair window is displayed.
3. Do one of the following:
• Select Automatic and select an existing disk pool or disk group from the table, then click Finish to automatically complete the
replicated pair creation process with the default secondary virtual disk selection and repository settings.
• Select Manual, then click Next to choose an existing virtual disk as the secondary virtual disk and define the repository
parameters for the remote side of the remote replicated pair.
The Remote Replicated pair is created.
The following occurs:
• Initial synchronization between the local storage array and the remote storage array automatically begins.
• The replicated pair and its properties are displayed under the individual virtual disk node for the secondary virtual disk.
• The Associated Replicated Pairs table is updated to show the replication information for the Remote Replication group.
Removing replicated pair from Remote Replication group
Removing a replicated pair from a Remote Replication group breaks the replication relationship between the primary virtual disk on the
local storage array and the secondary virtual disk on the remote storage array. Data on the virtual disks is not affected. As a result of this
operation, the primary virtual disk and the secondary virtual disk become standard, host-accessible, nonreplicated virtual disks.
When you remove a replicated pair from a Remote Replication group, the replication relationship is first removed on the local storage
array, then from the remote storage array.
NOTE:
Occasionally, when the removal process fails to complete on both storage arrays, the next data synchronization
initiated by the primary virtual disk to the secondary virtual disk is paused. The Logical view in the AMW may also show
an unresponsive secondary virtual disk. Removing the replication relationship on the local storage array must correct
the problem.
1. In the AMW of the local storage array, select the Storage & Copy Services tab.
2. Select the Remote Replication group containing the replicated pair you want to remove and select one of the following:
• Copy Services > Remote Replication > Remote Replication > Replication Group > Remove.
• From the Associated Replicated Pairs table in the right pane, select the replicated pair you want to remove and select Copy
Services > Remote Replication > Remote Replication > Replication Pair > Remove.
The Confirm Remove Replicated Pair window is displayed.
3. Type yes and click Remove.
NOTE:
When you remove a replicated pair, the system deletes the associated replication repositories. To preserve
them, de-select Delete replicated pair repositories.
