Basic information for enabling the controller enclosures for replication supplements the troubleshooting procedures that
follow.
l
Familiarize yourself with the replication feature overview provided in the Storage Management Guide.
l
For best practices concerning replication-related tasks, see the
HPE MSA Remote Snap Software Technical white
paper
.
l
In order to replicate an existing volume to a pool on the peer, ensure both the primary and secondary systems have
the MSA Advanced Data Services license installed and follow these steps:
l
Find the port address on the secondary system:
In the CLI, run the
show ports
command on the secondary system.
l
Verify that ports on the secondary system can be reached from the primary system using either method below:
l
In the CLI, run the
query peer-connection
command on the primary system, using a port address
obtained from the output of the
show ports
command above.
l
In the SMU, select Settings > Peer Connections and view Available Ports. View Current Peer Connections. You
can enter an IP address into the Peer System IP Address field and select the Query Peer Connection button to
view the result.
l
Ensure a pool exists on both the primary and the secondary systems.
l
Create a peer connection and replication set, using either method below:
l
In the CLI, run the
create peer-connection
command and then run the
create replication-set
command.
l
In the SMU, select Provisioning > Volumes > Data Protection > Add Data Protection > Remote Replication and
follow the on-screen directions to create the peer connection while creating the replication set.
l
Initiate replication.
l
In the CLI, run the
replicate
command.
l
In the SMU, select Provisioning > Volumes and select the slide-over to access the Replications panel. Click Start
Replication.
l
For descriptions of replication-related events, see the Event Descriptions Reference Guide.
Diagnostic steps for replication setup
The tables in this subsection show menu navigation for replication using the SMU.
IMPORTANT Remote Snap must be licensed on all systems configured for replication via the HPE MSA Advanced
Data Services license, and the controller module firmware must be compatible on all systems licensed for replication.
Can you successfully use the Remote Snap feature?
Answer
Possible reasons
Actions
Yes
System functioning properly.
No action required.
No
Remote Snap is not licensed on each
controller enclosure used for replication.
Verify licensing on each enclosure used for replication:
l
In the SMU, select Maintenance > Support > Licensing.
l
If the replication feature is not enabled, obtain and install the
MSA Advanced Data Services license.
l
For more information on licensing, see the topic about installing
a license in the Storage Management Guide.
