Before you begin Consider the following:
l Adding a Data Domain volume to a consistency group automatically sets its volume access mode to Read-Only. Data Domain volumes in a consistency group become writable when:
n Image access is enabled.
n The copy or consistency group containing the Data Domain volume is disabled.
l Backup copy LUNs can be on up to two Data Domain systems, per RPA cluster.
l A single Data Domain device may exist in more than one consistency group.
l Configure the Data Domains and XtremIOs.
l Create XtremIO initiator groups.
l Register the Data Domains, XtremIOs, and the block services for ProtectPoint pools.
l If one volume at a copy is on an XtremIO array, all other XtremIO volumes at that copy must be on the same array.
l For applications running on a host cluster:
The RecoverPoint system supports both local and remote high-availability host clusters.
n Place all volumes that are resources of the host cluster in a single consistency group. Simplify management by assigning the name of the host cluster as the name of the consistency group.
Note
The Journal volumes must not be resources of the host cluster.
n Assign each replication set the same name as its disk resource in the cluster. If all cluster nodes (hosts) at the side are down, you may not be able to create replication volumes. To correct this problem, either bring up the nodes, or run a rescan_san command from the CLI, with volumes=FULL.
n Before enabling a consistency group, the system Dashboard may show an Error on the source-side storage and display the message Volume cannot be accessed by any RPA. The errors are removed when the consistency group is enabled.
Procedure
1. Select Protection > Protect Volumes.
2. In the Select Production Volumes screen:
a. Define the consistency group name, the production name, and the RPA cluster that is to manage the production.

b. Select the production volumes in the volume list.
Note
If one volume at a copy is on an XtremIO array, all other XtremIO volumes at that copy must be on the same array. To help you identify the volumes, use the toolbar at the top-right corner of the screen.
Table 9 Toolbar options
Icon Description
To filter the volumes in the list by Size, Product, Vendor, Name, UID, LUN, or VPLEX Group.
To select the table columns that you want to display.
Note
To make the columns wider or thinner, drag the column dividers. In most cases, RecoverPoint remembers the column width that you define, and then displays the defined columns widths in each subsequent launch of this wizard.
To export the data in the volume list to a *.csv file.
To display context-sensitive help for this wizard screen.
c. (Optional) To define the group policies and copy policies now, click Modify Policies.
If you skip this step, you can define the policies later.
The policy settings are optional. The default values provide a practical configuration. It is recommended that you accept the default settings unless there is a specific business reason to set other policies.
d. Click Next Define the Production Journal.
3. In the Define Production Journal screen, perform the following steps in the volume list for Select Provisioned Journal Volumes:
a. Select the volumes to add to the journal.
For XtremIO arrays, the journal need not be more than 10 GB for non-distributed consistency groups and 40 GB for non-distributed consistency groups, since the XtremIO journal contains only pointers to snapshots and metadata.
For best performance, select volumes that are identical in size. If identically sized volumes are not available, select volumes that are similar in size.
To help you identify the required volumes in the volume list, use the toolbar icons at the top-right corner of the screen.
b. Click Next Add a Copy.
4. In the Add a Copy screen:
a. Define the Copy Name.
b. Select the same RPA Cluster as the one managing the XtremIO production volumes.
Note
Ensure one or more Data Domains have been masked to this RPA cluster.
c. Select the Add Data Domain Copy checkbox.
d. (Optional) To define the way in which RecoverPoint replicates the
production data to the selected copy, set the snap replication mode and the RPO.
e. (Optional) To enable RecoverPoint to automatically delete the device group, its block services for ProtectPoint pools, and static images on the Data Domain if this copy is deleted, click Modify Policies, and then in the Copy Policy tab select Delete journal upon removal.
To change the protection settings using policy templates, in the Link tab, use the Select Template list box to select one of the templates. To load the settings in the template, click Load, and then to apply the settings, click OK.
f. Select the Data Domain system to use as the copy, and the block services for the ProtectPoint pool in which to store the Data Domain static-images.
Note
The Data Domain copy journal is automatically provisioned in the same resource pool as the copy. RecoverPoint automatically creates the backup block services for ProtectPoint device groups and the devices to populate the specified pool.
g. To continue configuring the group, click Next Display Group Summary.
5. In the Group Summary screen:
a. Use the following options until the consistency group diagram reflects the requirements:

Action Description
Edit Opens the Add a Copy screen of the copy whose Edit link you clicked, allowing you to edit the copy settings, and modify the copy volume configuration, replication mode, or protection plan.
Delete Removes the copy whose Delete link you clicked, from the consistency group.
Note
You cannot delete the production copy.
Replication Sets
Displays detailed volume information on all replication set volumes that have been defined for the consistency group. To display the associated volume information in the bottom section, select a row in the replication sets table in the top section.
