Isolating Remote Snap replication faults 49
Replication setup and verification
After storage systems and hosts are cabled for replication, you can use the SMU to prepare to use the Remote Snap
feature. Optionally, you can use SSH to access the IP address of the controller module and access the Remote Snap
feature using the CLI.
NOTE: Refer to the following references for more information about replication setup:
• See HPE Remote Snap technical white paper for replication best practices: MSA Remote Snap Software
• See HPE MSA 1050/2050 SMU Reference Guide for procedures to setup and manage replications
• See HPE MSA 1050/2050 CLI Reference Guide for replication commands and syntax
• See HPE MSA Event Descriptions Reference Guide for replication event reporting
Basic information for enabling the MSA 1050 FC or iSCSI controller enclosures for replication supplements the
troubleshooting procedures that follow.
• Familiarize yourself with replication content provided in the SMU Reference Guide.
• For best practices concerning replication-related tasks, see the technical white paper.
• In order to replicate an existing volume to a pool on the peer—ensure both the primary and secondary systems have
the Remote Snap license installed—and follow these steps:
 Find the port address on the secondary system:
Using the CLI, run the
show ports command on the secondary system.
 Verify that ports on the secondary system can be reached from the primary system using either method below:
–Run the
query peer-connection CLI command on the primary system, using a port address obtained from
the output of the
show ports command above.
–In the SMU Replications topic, select Action > Query Peer Connection.
Ensure a pool exists on the secondary system.
 Create a peer connection.
To create a peer connection, use the
create peer-connection CLI command or in the SMU Replications topic,
select Action > Create Peer Connection.
 Create a replication set.
To create a replication set, use the
create replication-set CLI command or in the SMU Replications topic,
select Action > Create Replication Set.
 Replicate.
To initiate replication, use the
replicate CLI command or in the SMU Replications topic, select Action >
Replicate.
• 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, and the controller module
firmware must be compatible on all systems licensed for replication.
