Replication Setup And Verification; Diagnostic Steps For Replication Setup - HP MSA 2050 User Manual

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 manuals for more information about replication setup:
• See HPE Remote Snap technical white paper for replication best practices
• See HPE MSA 2050 SMU Reference Guide for procedures to setup and manage replications
• See HPE MSA 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 2050 SAN 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 in the primary system or secondary system, 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.
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.
