Create a Replication Partner

Before you begin

If you are using HPE Cloud Volumes (HPE CV), you must first create a replication store on HPE CV before you can create a replication partner on the on-premises array.

Use the management subnet for replication when any of the following conditions apply:

Your data IPs are not routable across the network.
You want to separate replication traffic from iSCSI traffic.
Your replication HPE Nimble Storage arrays are running NimbleOS 1.4, 2.0 or later.

Note:

For NimbleOS 2.x and later, replication over a data subnet is available; however, it requires that the replication control traffic to be transferred over a management subnet. If you choose to replicate over a data subnet, you must be able to do the following:

Route the management subnet between replication partners by the default gateway for replication control traffic.
Route the data subnet between replication partners by a static route for replication data transfer traffic.

Note: For Fibre Channel (FC) arrays, you do not need to separate the replication traffic; replication traffic never runs over FC.

Procedure

Select Manage > Data Protection , then click Replication Partners in the left pane.
Click Add to add a new replication partner.
Select a replication type. If you select Cloud Replication, enter the credentials for your volume.
Type the group name of the replication partner for on-premises replication or select a replication store for HPE CV replication.
Note: The Group name must be identical to the Group name of the Replication Partner. This name is case sensitive.
(Optional) Type a description of the partner group.
Perform the following steps for on-premises replication only.
1. Type the hostname or IP address of the partner group.
2. Type a shared secret. Type it again to confirm.
  Note: The shared secret must be eight or more printable alphanumeric characters with no spaces or special characters. Special characters include: ' " ` ~ ! @ # $ ^ & ( )+ [ ] {} * ; : ' " . , | < > ? / \ = % .
3. Choose which subnet to use for the replication network. Select one of the following options:
  - Use management or controller IP addresses for replication traffic
  - Use data IP addresses for replication traffic
  Note: For NimbleOS 2.x or later, replication over a data subnet is available; however, it requires that the replication control traffic transverse a management subnet.
Select a location for the inbound replication pool from the Inbound Location list.
(Optional for on-premises replication) Check Use the same pool and folder as the source location.
Click Next.
(Optional) To create a Quality of Service (QoS) policy, which is a bandwidth limit for replication traffic, click Add Policy and complete the fields in the dialog box.
Note: A QoS policy defines how the network resources are allocated for the replication partner. Without a QoS policy, the replication partner can use unlimited network bandwidth.
1. (Optional) Type a description of the policy.
2. Type a number value and choose a bandwidth in Kbps or Mbps.
3. Indicate the time interval when the policy is in effect. The time should be the time in the array time zone, not the client time zone.
4. Check the boxes for the days of the week when the policy is in effect.
5. Click Create.
Click Create. It can take up to ten minutes for the partners to establish contact.

What to do next

Log in to the replication partner and perform the same configuration steps on the downstream array and group. For HPE CV replication, configuration of the downstream array is not necessary.
